Energy challanges
World energy demand is increasing
Energy related environmental impactscontinue to grow
Access to affordable energy is 2.4 billion people are without clean, safe
cooking fuel and depend on traditionalbiomass
1.6 billion people are without electricity

New and renewable energy
Refers to energy resources which arenaturally replenished:
Wind,
Solar, Hydropower,
Biomass,
Geothermal energy
Ocean energy
Renewable energy is mainly produced andused domestically

New and renewable energycurrent developments
By the end of 2004, renewable energy supplies17 per cent of the total primary energy.
Traditional biomass (for cooking and heating) is
growing just slowly as it is used more efficientlyor replaced by more modern energy sources;
Large hydropower is growing slowly
New renewables (small hydro, modern biomass,wind, solar, geothermal and biofuel) are growingvery rapidly.

New and renewable energyinvestments
Modern applications of renewable energy havegrown steadily over the past three decades
The investment to developing renewable energy
capacities in countries is growing rapidly (from$6 billion in 1995 to $30 billion in 2004)

N/A Renewable energyisderived from natural
processes that are
replenished constantly.
In its various forms, it
derives directly or
indirectly from the sun,
or from heat generated
deep within the earth.
Included in the
definition is energy
generated from solar,
wind, biomass,
geothermal,
hydropower and ocean
resources, and biofuels
and hydrogen derived
from renewable
resources.
Renewable energies
cover hydropower,
wind energy, solar
energy, biomass and
wastes and geothermal
energy. Renewable
energies are the sum of
hydropower, wind
energy, solar energy,
biomass & wastes and
geothermal energy.
Renewable energy
resources: Energy
resources that are
naturally replenishing
but flow-limited. They
are virtually
inexhaustible in
duration but limited in
the amount of energy
that is available per
unit of time.
Renewable energy
resources include:
biomass, hydro,
geothermal, solar,
wind, ocean thermal,
wave action, and tidal
action.
Renewable energy
consists of energy
produced and/or
derived from sources
infinitely renovated
(hydro, solar, wind) or
generated by
combustible
renewables
(sustainably produced
biomass); usually
expressed in energy
units and, in the case
of fuels, based on net
calorific values.
Renewables,
excluding
Hydroelectric shows
the amount of energy
consumed from
renewable sources
such as wind; tide,
wave and ocean;
thermal and
photovoltaic solar;
primary solid biomass;
liquid biomass and
biogas; and geothermal
systems.

Charcoal:
Solid residue,
consisting
mainly of
carbon, obtained
by the
destructive
distillation of
wood in the
absence of air.
Charcoal: Covers the solid
residue of the destructive
distillation and pyrolysis of
wood and other vegetal
material.
1. Wood Charcoal:
Wood carbonised by partial
combustion or the application of
heat from external sources. It
includes charcoal used as a fuel
or for other uses, e.g. as a
reduction agent in metallurgy or
as an absorption or filtration
medium. It is reported in
metric tonnes.2. Charcoal: Covers the solid
residue of the destructive
distillation and pyrolysis of
wood and other vegetalmaterial.
N/A Charcoal: refers to asolid residue derived
from the
carbonization,
distillation, pyrolysis
and torrefaction of
wood (from the trunks
and branches of trees)
and wood by-
products, using
continuous or batch
systems (pit, brick and
metal kilns). It also
includes charcoalbriquettes.
N/A
Black
liquor:N/A Black liquor: This is a
recycled by-product formed
during the pulping of wood in
the paper making industry. In
this process, lignin in the
wood is separated from
cellulose, with the latter
forming the paper fibers.
Black liquor is the
combination of the ligninresidue with water and the
chemicals used for the
extraction of the lignin and is
burned in a recovery boiler.
The boiler produces steam and
electricity and recovers the
inorganic chemicals for
recycling throughout the
process.
N/A Black liquor: Abyproduct of the
paper production
process, alkaline
spent liquor, that
can be used as a
source of energy.
Alkaline spent
liquor is removed
from the digestersin the process of
chemically pulping
wood. After
evaporation, the
residual black
liquor is burned as
a fuel in a recovery
furnace that
permits the
recovery of certain
basic chemicals.
Black liquor: is the
alkaline-spent liquor
obtained from the
digesters in the
production of sulphate
or soda pulp during
the process of paper
production, in which
the energy content is
mainly derived fromthe content of lignin
removed from the
wood in the pulping
process.
