Different sources of energy

A presentation about:

Nowadays,there are so many different sources of energy.The most well-known ones are:

Nuclear energyNatural gasSolar powerWind power energyBiomass

Nuclear energy

Nuclear energy is the use of exothermic nuclear processes to generate heat and electricity.It is also a low carbon power generation method of producing electricity.

Nuclear energy has disadvantages:

It is a chemical weapon(bomb in Hiroshima-Nagashaki)Nuclear power plant accidents(Chernobil and Fukushima disaster)High cost:it needs a lot of investment to set up a nuclear power stationNon Renewable:This energy uses uranium which is rare to be found in many countries.

Natural gasNatural gas is a fossil fuel formed when layers of buried plants and animals are exposed to intense heat and pressure over thousands of years.The energy that the plants originally obtained from the sun is stored in the form of carbon in natural gas.

Natural gas has also disadvantages:

It creates greenhouse gas emissionsIt is renewable:but some people call it non-renewable because it needs thousands of years to start forming under the ground againIt is highly volatile and can be dangerous

Solar powerSolar power is the conversion of the energy from the sun to usable electricity.The most common source of solar power is photovoltaic cells which convert sunlight into electricity.It is renewable and it is not only used to generate electricity but also to heat water(solar water heaters)

Some disadvantages of solar power

It cannot be created during the nightIt is also reduced during times of cloud cover(although energy is still produces in a cloudy day)Solar panels are expensive

Wind power energy

Wind power is the conversion of wind into electricity.The most common form of wind power generation uses wind turbines which can be built at varying sizes to create varying amounts of electricity.It is a completely clean energy source,the turbines can be placed everywhere.

Wind power disadvantages:

Like many alternative energies,wind power is not always generatedWind turbines are very noisy

Biomass

Biomass is a biological material derived from living or recently living organisms.It most often refers to plants or plant-derived materials.Biomass creates no harmful carbon dioxide emissions and it is a clean energy and renewable.It also reduces landfills and can be used to create different products.

Disadvantages of biomass:

It is expensiveAnd harmful to the environmentIt consumes more fuelRequires more land(so biomass products can be burnt)

So those are the most well-known energy resources.Some of them have loads of disadvantages and some more advantages.The most of them produce fossil fuels so they participate in global warming.The “cleanest”one is wind power and it does not take part in global warming.
