Transportation of biodiesel
02 November 2011
Biofuel supporters say the industry helps the environment, creates jobs, and boosts economic growth. Nonetheless,
biodiesel fuel remains a polemic issue. Despite the supposed economic and environmental benefits of increased
biodiesel production, the industry has its critics, largely due to its potential impact on food supply.
Carlos St James, businessman and president of the Argentine Renewable Energy Chamber, believes the government is
starting to pay more attention to cleaner forms of energy with the development of wind and solar panels and of course, 5 the biofuel industry. In the country, the biodiesel industry has grown by 2,250% since 2006 and has become the
world’s fourth largest producer. Figures show the country can produce 2, 5 million tons by the end of this year, which
will bring US$3bn to the economy. Growth is expected to be propelled further by a law approved last year stating that
all petroleum derived fuel in Argentina should include 7% of biodiesel. Investors, drawn to Argentina’s large
agricultural sector, relatively cheap land and inexpensive labor, are plowing millions into biodiesel production. 10 According to Roberto Urquía, a former senator and one of the biggest producers of biodiesel in the country, by 2015
biodiesel production in Argentina will reach 7million tons, almost triple the current output.
Conversely, detractors claim that biofuel production poses a major threat to global food systems and the natural
environment. 99% of the biodiesel produced in Argentina is the first generation type, which means it is made out of
food-producing plants like soybeans, canola and palm trees. The national production focuses mainly on the oil derived 15 from soybeans. The use of first generation biodiesel divides opinion since the biodiesel and food industries will be
competing with each other to get the material for their final products. If more crops are processed as biodiesel, fewer
are harvested for food, causing prices of basic foods to rise.
“In a world with hunger it is unjust to use food to produce fuel”, states St James. On the other hand, he says that “the
food vs. fuel debate doesn’t apply to the soybean biofuel,” which is the one mainly produced in Argentina. The reason 20 is that the sectors require different parts of the soybean plant: 85% is protein and used to produce food, whereas soy
oil used for the production of biodiesel is the rest. “Argentina is producing more and more soy, which complements
food production. This means the more soy you have, the more food you get.”
Even so, there are two potential soy crops per year and the ideal to have a healthy soil is to alternate crops, since the
soybean plantation takes a lot of nutrients out of the soil. In spite of this, the farmers in Argentina are planting soybean 25 crops over and over again, which might lead to infertile lands and scarcity of agricultural products for both food and
biodiesel in the future. Furthermore, Argentina only consumes a small fraction of its national soy crop (most is
exported to China), so increased soy production at the expense of other crops such as wheat and corn can affect
national food supply.

Greener Hybrid Power Plants Proposed
Circle the correct option to complete each exercise in sections 1 - 5
1. Predicting (5)
What do you think the text will be about?
a. Fuel-based power stations will be banned
b. There is a proposal to paint all power plants in green
c. Many environmentally friendly power plants run on solar energy
d. Power plants could be powered by a mixture of fuel and solar energy
04 Nov 2011
First, there were hybrid cars; now green hybrid power plants are on the way, say university researchers. Hybrid cars,
powered by a mixture of gasoline and electricity, have become a practical way to "go green" on the roads. Now
researchers at Tel Aviv University are applying the term "hybrid" to power plants as well. Hybrid power plant is a
potentially cost-effective and realistic way to integrate solar technology into existing power plants.
Many power plants use traditional fuel to make energy, says Tel Aviv University professor Avi Kribus, from the 5 School of Mechanical Engineering. Others that are more environmentally friendly run on solar thermal power. In a
solar thermal power plant, sunlight is harvested to create hot high-pressure steam, approximately 400 to 500 degrees
centigrade. This solar-produced steam is then used to rotate the turbines that generate electricity. However, solar
thermal power plants can be costly to construct and operate. The cost of the equipment that harnesses the energy is
expensive, as it is made from valuable metals. 10
As a hybrid alternative, Professor Kribus and his graduate student Maya Livshits, have developed a new technology
that combines the use of conventional fuel with the lower pressures and temperatures of steam produced by solar
thermal power allowing plants to be hybrid, replacing 25 to 50 percent of their fuel use with green energy. They have
devised a new steam-injection gas turbine method that employs both fuel and steam from solar power, so plants can
use green energy for up to half of their power needs. 15
Prof Kribus, says, "We combine a gas turbine, which works on hot air and not steam, and inject the solar-produced
steam into the process. We still need to burn fuel to heat the air, but we add steam from low-temperature solar energy,
approximately 200 degrees centigrade. This hybrid method is not only highly efficient in terms of energy production,
but the lowered pressure and heat requirements allow the solar part of the technology to use more cost-effective
materials, such as common metals and low-cost solar collectors”. 20
The hybrid fuel and solar power system may not be entirely green, but it does offer a more realistic option for the
short and medium term. Electricity from solar thermal power plants currently costs twice as much as electricity from
traditional power plants. If this does not change, the technology may never be widely adopted. The researchers hope
that a hybrid plant will have a comparable cost to a fuel-based power plant, making the option of replacing a large
fraction of fuel with solar energy competitive and viable. 25
The researchers have approached an Indian university to further develop the project and are interested in contacting
corporate partners who are willing to put hybrid technology into use. They think that it is a stepping-stone that will
help introduce solar energy into the industry in an accessible and affordable way.

b. The Second Earth Summit will modify Climate Change
c. The Second Earth Summit will contribute to Climate Change
d. The Second Earth Summit will address a topic other than Climate Change
Tue, Jan 24 2012
Representatives from around the world will gather in Rio de Janeiro next June to try to hammer out goals for
sustainable development at a U.N. conference, Rio+20. In an attempt to avoid too much confrontation, Rio+20 will
focus not on climate change but on sustainable development - making sure economies can grow now without
endangering resources and the environment for future generations. The conference’s objective is to secure renewed
commitment to sustainable development and to meet new and emerging challenges by focusing on the following 5 themes: the green economy in the context of sustainable development and poverty eradication; and the institutional
framework for sustainable development.
U.N. conferences over the two past decades have begun with high hopes for agreements to compel nations to cut
climate-warming emissions and help adapt to a hotter world, but they often ended with disappointingly modest results.
That first Earth Summit in 1992 ultimately led to the carbon-capping Kyoto Protocol and a treaty on biodiversity. As a 10 result, the focus of subsequent global meetings has been on the reduction of greenhouse gas emissions, especially
carbon dioxide. However, the world's biggest emitters, including China and the United States, have balked, arguing it
would cripple economic development. Sustainable development is an easier sell globally than climate change, even
though sustainable development is a way of tackling global warming and other environmental issues. Therefore, this
summit offers a chance to renew political will to make the world's economies greener. 15
Climate change is an issue that has very strong resistance from sectors that are going to be substantially altered, like
the oil industry. Sustainable development is something that is as simple as looking at how we would like to be in 10 or
20 years. The time seems ripe. Natural resources are at stake. The global human population tops 7 billion. Traditional
economies are failing. And the planet is warming. Leaders may accept the premise that it makes sense to ensure that
rich and emerging nations can grow without further damaging the environment. 20
A draft document was released on 10 January in New York as a starting point for the June conference, outlining
several issues. The ‘zero draft’, as it is called, identifies a number of key issues: food security, water, energy, cities,
green jobs-social inclusion, oceans, seas and small island developing states, natural disasters, climate change, forests
and biodiversity, land degradation and desertification, mountains, chemicals and waste, consumption and production,
education, and gender equality. 25
Brice Lalonde, the UN's executive coordinator of the conference said the Second Earth Summit in June "must be the
place where decisions on the future of the planet are made and not just another talking shop for world leaders". He
added "The draft is a good start. Most topics are on the table: from efficient international co-operation to sustainable
development goals, from a regular review of the state of the planet to an agency for the environment, from universal
access to energy to social safety floors. What is missing now is one verb: to decide. Because to stress, urge, call, 30 recognize, underscore, encourage, support or reaffirm is not enough. When heads of state meet, it should be to
decide".

Cross Theme Park – Santa Ana
Ecotourism is defined as leisure travel that provides tourists with an educational and adventurous experience by
visiting complex and fascinating ecosystems and their associated cultures and traditions. This includes activities such
as eco-friendly trekking, boating and whale and dolphin watching. The concept of ecotourism began in the late 1980's
and increased in popularity in 2002 during the United Nations "International Year of Ecotourism."
According to environmental organizations and others, ecotourism should have a minimal impact on both the 5 environment and the culture. Ecotourism should inform tourists about what is needed to sustain the environment they
are visiting, and should also help local populations understand the importance and value of their home. Ecotourism
can also help foster a sense of environmental awareness by encouraging travelers to be mindful of wasting resources
and polluting the environment. Ecotourism can also help local economies by generating revenue and jobs, which
further encourages the local population to preserve its environment. 10
A good ecotourism operation will strive to support the community and encourage travelers to be culturally sensitive
by training and employing local people and by purchasing local supplies and services to further stimulate the
economy. Tourist regions in many countries now rely on ecotourism as the primary source of revenue. Ecotourism
plays a particularly important role because it can create jobs in remote regions that historically have benefited less
from economic development programs than have more populous areas. Even a small number of jobs may be 15 significant in communities where populations are low and alternatives are few.
The education and good practices taught by ecotourism may also help foster sustainable development in a world
increasingly faced by destructive practices such as clear-cutting forests and poor land-use policies that destroy
habitats. Unless ecotourism actively incorporates local society into service planning and provision, and includes
programs to meet the fundamental needs for income and employment for all people in the region, the special qualities 20 of the site and its flora and fauna may be irreparably damaged.
Although the overall concept and intent of sustainable tourism is positive, the industry is not without its critics, largely
due to companies which abuse the concept of ecotourism to take advantage of the wealth generated by the interest in
it. Some ecotourism operators have been accused of masking their environmentally destructive practices by marketing
their businesses as ecotourism with little or no recognition at all of its key ideals and principles. 25
Hopefully, with time, the standards for good ecotourism will be established and both travelers and the industry will be
aware of what constitutes an ecologically and culturally sensitive tourism. If approached correctly, ecotourism could
become an essential cog in the wheel of conservationism. In the past, man has largely served as a foe to the
environment. By fostering travel that reinforces good environmental practices and promotes economies, ecotourism
might cultivate a symbiotic relationship between humankind and the environment that will benefit all of us in the end. 30

The growth of bio-energy into a mega industry
Circle the correct option to complete each exercise in sections 1 – 5
1. Predicting (5)
What do you think the text will be about?
a. The current impact of bio-energy on the industry
b. The promising future of the bio-energy industry
c. The world’s forthcoming competition for bio-energy production
d. The impending depletion of natural resources by the bio-energy industry
April, 2012
Creating an analogy with the emergence of the oil industry over a century ago – we are about to
witness the growth of bio- energy into a mega industry. The crude oil of this future global-industry
will be biomass and supply will be the key driver for many years to come. Brazil is set to become
the Saudi Arabia of the business; and control over supply will be a critical success factor for those
destined to become the new energy players. The window of opportunity to start developing such a 5 business is now.
Biomass is the source of bio-energy derived from living or recently living organisms that can be
processed into electricity, liquid or solid biofuel and heat. Traditional biomass, which represents
about half of total biomass consumption today, is wood fuel, agricultural by-products and dung
burned for cooking and heating purposes in developing countries. This is still widely harvested and 10 used in an unsustainable and unsafe way. On the other hand, modern biomass is produced from
sustainable wood-based products, energy crops, forestry residues, residual agricultural products and
can be broadened to include municipal and industrial waste.
Modern biomass fuels are generally recognized as having far lower lifecycle carbon dioxide
emissions than fossil fuel equivalents and can play an important role in carbon capture and 15 sequestration (CCS). Despite this, significant concerns remain about sustainability in two key
areas: some first generation liquid biofuels, which compete with food production; and the forestry
management techniques used in production of woody biomass. However, second generation liquid
biofuels, based upon lingocellulosic feedstocks, hold the promise of sustainable production and
overcome most of the criticisms of first generation fuels. Likewise, production of biomass from 20 renewable energy crops can avoid many of the negative issues with woody biomass.
According to the World Bank Development Report, modern biomass has the highest mitigation
potential for GHG emissions of all renewable energy sources, but it is the area where technology is
least developed. Underlying global demand for energy by 2050 could triple from its 2000 level if
emerging economies follow historical patterns of development. Natural innovation and competition 25 could spur improvements in energy efficiency to moderate underlying demand by about 20% over
this time. Furthermore, unlike electric cars, or hydrogen fueled vehicles, biofuels derived from
biomass are already generated on an industrial scale and can be applied largely within the existing
infrastructure.
In future scenarios, biomass fuels represent around 15% of global primary energy by 2050. Liquid 30 biofuels become a significant part of this, in particular, helping to diversify the supply of transport
fuel. More optimistic projections estimate that by 2050 bio-energy could supply about 25% of the
world’s primary energy by 2050 - broadly equivalent to the total contribution of the oil & gas
industry by that time. Either case implies the creation of a massive global bio-energy industry over
the coming 20 to 30 years to achieve the target. 35

a. Rio+20 final document has not been made public yet
b. Rio+20 outcome fell short of the world’s expectations
c. Rio+20 Earth Summit has been put off until further notice
d. Rio+20 Earth Summit has come to an end before the scheduled date
Monday, July 2, 2012
The U.N. Conference on Sustainable Development, or Rio+20, was held in Rio de Janeiro on June 20-22 as a
follow up to the 1992 U.N. Conference on Environment and Development also held in the Brazilian city. Some
40,000 people – including Heads of State and government, representatives from non-governmental
organizations and the private sector – have been in Rio de Janeiro for three days, attending the Earth Summit,
and seeking to help shape new policies to promote global prosperity, reduce poverty and advance social equity 5 and environmental protection.
Unfortunately, the statement adopted by Rio+20, titled "The Future We Want," failed to get individual
governments to express their clear political determination to resolve problems and to incorporate concrete
programs. The document contains few proposals for concrete action and few promises to achieve the goals.
"The Future We Want" referred to the importance of promoting the green economy. However, pursuit of the 10 green economy was left to the discretionary decisions of individual governments.
Economic development in the 20th century was achieved at the cost of environmental destruction. To prevent a
global catastrophe, it is imperative to fundamentally change the shape of economic activities and to promote the
"green economy". These objectives can be achieved by making serious efforts to reduce greenhouse gas
emissions and to economize on the use of natural resources. 15
The number of wildlife species facing extinction is rising. Every three years, forestland as large in area as the
Japanese archipelago is lost. Fishery resources such as tuna and cod are rapidly declining. At the same time,
global economic disparity is widening. While developed countries are squandering large amounts of energy,
some 2.3 billion people in developing countries do not have access to modern energy sources. Yearly, some 9
million children die before reaching the age of 5, mainly due to poverty. 20
Developing countries feel that the green economy may hamper their economic development. They also believe
that efforts by developed countries to protect the environment are inadequate. Developed countries must heed
these countries' voices, which are warning that they cannot pursue the green economy without support and
assistance from developed countries. Regrettably, leaders of developed countries such as U.S. President Barack
Obama, Japanese Prime Minister Yoshihiko Noda and German Chancellor Angele Merkel did not attend 25 Rio+20.
Still suffering from the Fukushima nuclear power crisis, Japan should be the first to realize that nuclear power is
hazardous to the environment and strive to build a model economy based on renewable energy sources, such as
solar and wind power. Unfortunately, this does not appear to be happening. Quite the opposite, this weekend,
Japan re-entered the nuclear age. A reactor at the Ohi nuclear power plant was reactivated last Sunday, the first 30 power plant to go back online since the nation closed all its reactors in the wake of the Fukushima crisis over a
year ago.

Argentina could become a green energy powerhouse
Circle the correct option to complete each exercise in sections 1 - 5
1. Predicting (5)
What do you think the text will be about?
a. Argentina’s fossil fuels will eventually become depleted
b. Argentina will become an green energy importer
c. Argentina is earnestly investing on green energy
d. Argentina does not have the resources to develop green energy
The solar and wind energy business is booming in South America. With a unique combination of
favorable climactic and environmental conditions the countries in the Southern Cone of South
America offer much untapped potential in one of the world's fastest growing energy sectors. By 2015,
13 percent of Brazil's national energy grid will be produced from renewable sources. In addition,
Uruguay's wind farms will generate 1,500MW of alternative energy. Argentina is looking to power 5 ahead with its energy industry.
At present, Argentina relies mainly on thermal power and hydropower to meet its energy needs. It
currently produces about 29,000 megawatts of electricity per year, but demand has increased by about
4 percent each year over the past 40 years. If this trend continues, by 2025 the country will need to
double its energy production to meet the expected demand for 61,000 megawatts. Argentina - and 10 other countries in South America - have two options: boost renewable energy capacity or import
energy. Argentina is now encouraging foreign companies to invest in renewable energy in the country.
In the last few years, Argentina has undergone the highest level of growth with regards to renewable
energy installations, making the country one of the most interesting for projects dedicated to the green
economy. One of the other driving forces behind the development of green energy in the country is the 15 protection of its ever more coveted ecosystems. Irresponsible deforestation, open-air mining and
drilling increasingly face opposition from the public. Natural resources from Argentina's all-day
sunshine and wind-swept prairies are less contentious, and are increasingly being used by communities
in remote areas of Argentina.
At the beginning of this year the Argentine government started a fund to encourage innovative small 20 projects to use solar power to help tackle poverty and social development. The fund has access to
almost $8 million dollars to distribute to small-scale schemes that aim to improve welfare for the
poorest sector of society through health, housing or agriculture. The scheme is expected to be rolled
out across the country. In one such project, solar panels are regularly seen on houses in Buenos Aires
and beyond, which cuts reliance on bottled gas and electricity on the grid. In the remote Andean north 25 west of Argentina, tiny communities far from power lines are using high tech, low cost solar
technology to become self-sustainable energy autonomous towns.
Just like decades ago Argentina appeared to look forward to a prosperous future because of its
abundant grain crops and meat production, feeding a large chunk of the world, currently there is
another possibility, that of providing energy for the planet. Experts say that Argentina has great 30 potential because of the different kinds of territories and geographical conditions that could lend
themselves to develop solar energy, wind energy, geothermic energy and tidal energy. “Argentina is
potentially a great clean energy exporter, which is exactly what the world wants in the 21st century,”
specialists agree.

Opposing Hydroelectric Projects in South America
Circle the correct option to complete each exercise in sections 1 - 5
Protests against hydroelectric plants in South America may not have attracted as much attention as
those against opencast mining, but names such as Brazil’s Belo Monte have made headlines beyond
the region. One thing is certain: South America is going after hydroelectricity in a big way. Many of
the projects are in the large to “mega” categories, and these are most likely to be the main target of
protest actions in coming years. 5
In Peru, where two-thirds of the existing plants have less than 15MW, two-thirds of the 79 planned
new ones are either large or “mega.” While Peru’s largest existing plant has 798MW, 11 of the
planned new ones are bigger than that. Ecuador has 16 hydroelectric plants, of which only 4 have
more than 100MW, one of them exceeding 1,000MW. Of the 18 planned new ones, 5 are in the
“mega” category. In Bolivia only one of the existing plants has more than 100MW, while 8 of the 10 10 planned new ones are in the large or “mega” brackets.
Reaching further downstream in the Amazon basin is the hydroelectric complex of the Madeira River,
which has been billed as the main scheme by the Initiative for the Integration of the Regional
Infrastructure of South America (IIRSA) and the biggest anywhere in the basin, with 4 interconnected
plants — 2 in Brazil, one in Bolivia and one on the river that serves as the boundary between Bolivia 15 and Brazil.
South of the Amazon basin and east of the Andes, major hydroelectric expansion is planned in Brazil,
partly on its own, partly with Argentina, the latter also planning expansion jointly with Paraguay. Over
the coming 10 years, in order to meet the projected increase in demand for electricity, Brazil will need
to install new generating capacity equal to 3 times that of the Brazilian-Paraguayan Itaipú. 20
In the Uruguay River basin there are already 5 hydroelectric plants with a joint installed capacity of
5,181MW. Apart from the planned 2,700MW Garabí-Panambí complex there are 2 other projects
which will jointly add 1,469MW. On the Paraná River, which already has 2 mega-hydros (the
14,000MW Itaipú and the 4,050MW Yaciretá), a 3rd project, the 4,608MW Corpus, is likely to be
reactivated fairly soon. 25
Protests against hydroelectric projects have become widespread enough to prompt the creation of a
network of “movements against dams” because of their perceived — and sometimes evident — social
and environmental impacts. Many factors are at play, and both sides have valid arguments.
Governments and private companies involved do invoke economic imperatives and tend to play down
potential environmental and social impacts. Protesters tend to portray all hydroelectric projects as 30 “mega-dams” In common with anti-mining campaigners and other movements, they accuse
governments of seeking to “criminalize social protest,” even when their actions are clear and
substantial breaches of the law.

Looking to Cities in Search of Global Warming’s Agricultural Benefits
Circle the correct option to complete each exercise in sections 1 - 5
Heat, carbon dioxide and air pollution are already having significant effects on trees, plants and crops.
A growing number of scientists are studying how plants react to elevated levels of greenhouse gases
and other pollutants. They are carrying out research in cities, where there are significant emissions of
atmospheric gases. They have started to explore how rising levels of heat and emissions might provide
at least some benefits for the planet. 5
There is a lot of emphasis on the mitigation of global warming. At the same time we need to think
about the tools we have at hand, and how we can use them to make climate change work for us.
Among the tools are cities, which have conditions that can mimic what life may be like in the
temperate zone of a heated planet. The effects of higher, mostly urban emissions are what prompted
scientists to reappraise global warming as a potential benefit to humanity. They have argued that an 10 expected increase in world population from 7 billion to 9 billion people by 2050 will require a green
revolution to enhance yields of basic grains. Carbon dioxide could be the answer.
In the last 50 years world atmospheric carbon dioxide concentrations have risen to 392 parts per
million and could reach 1,000 ppm by the end of this century. While plants need carbon dioxide and
generally perform better with higher concentrations of it, not every species responds positively to it. 15 Breeders are not actively selecting for CO2 response. They are more interested in drought resistance
and pest control. In the wild, however, nature selects for what works better. The assumption is that
nature in the wild will select plants which thrive in CO2 rich air. Scientists should be able to find the
wild progenitors of crops. If they are successful, we will get a double value, i.e. what we want is to
absorb more CO2 and exploit the CO2 as a means to increase yield. That is the goal. 20
Cities produce high levels of atmospheric carbon dioxide, nitrogen oxide and ozone, all of which
influence plant performance. Nevertheless, it is clear that there are some emissions that are not helpful
to plants. For instance, while cottonwoods are sensitive to ozone, many plants are susceptible to its
effects. Ozone can severely damage plant pores, causing them to grow more slowly. In addition,
nitrogen oxide also hampers the growth of plants by triggering inhibition of photosynthesis and 25 nitrogen metabolism.
However, scientists caution that while the studies on the influence of greenhouse gases on plant
growth in the cities may be a way to preview what the temperate zone might be like in the future;
faster plant growth in the northern hemisphere could mean trouble in hotter latitudes. In short, whereas 30 greenhouse gases may help plants grow more vigorously; fast plant growth may also cause
environmental disruptions.
