Fossil fuel plants
A fossil fuel plant is a system used to convert fossil fuel energy to mechanical work or electric energy.
Fossil fuel plants produce energy by using some form of heat energy to turn water into steam.
The highly pressurized steam then travels through pipes to push blades in a turbine. The turbine begins to turn, causing giant wire coils inside the generator to turn. This creates an electromagnetic field, which forces electrons to move and starts the flow of electricity.
In a fossil fuel plant, some type of fossil fuel is burned to create the heat that is needed to produce steam. Fossil fuels include coal, oil (also called petroleum) and natural gas. The fossil fuels were formed millions of years ago from plants and animals that died and decomposed beneath tons of soil and rock.
Renewable energy?..
- Environment and Climate
.Renewable energy is a clean energy. The extraction and use of fossil fuels generate very high environmental impacts, they produce toxic solid waste, consume high volumes of water and emit large amounts of hazardous gases (dust, mercury, dioxin) and greenhouse gases (CO2, sulfur dioxide, nitrogen oxides).
The pollutants from these activities are the main cause of respiratory diseases and harmful phenomena for man and the environment such as acid rain.
The issue of climate change is a global environmental problem, and energy production is the most important cause of changing weather conditions on the planet.
Moreover, all this creates damage to agriculture, can cause extinctions, loss of naturalness and wastage of drinking water.
Renewable energy?..
- Reliability and Security
.There are many problems caused by the use of fossil energy sources. For example, the Fukushima nuclear disaster or environmental disaster on the oil platform of British Petroleum in the Gulf of Mexico.
There are different risks due to the use of fossil fuels, from the extraction to final use for the production of energy.
.All this does not occur when using renewable resources, the risk of accidents are almost completely absent, plants are always more reliable.
The production of energy is continuous and efficient.
And thanks to the specificity of resources, central installation can be performed near places requiring energy, safely.
Renewable energy?..
- Accessibility and inexhaustibility
.Coal, gas and oil are extracted from hidden deposits.
And to be used require costly and dangerous mining operations.
In addition, these deposits are physically limited!
.Renewable sources have the characteristics of being inexorable: the sun, the wind, the sea, geothermal energy have always existed and it will always possible to exploit their energy potential.

Biomass
Energy from biomass is a renewable energy source that depends on the cycle of living matter.
This energy is used to produce electricity using the heat generated by the combustion of these materials (wood, plants, agricultural waste, organic garbage) or biogas from the fermentation of these materials in biomass power plants.
Biomass
A biomass plant produces electricity with water vapor released by the combustion of plant or animal material, which moves a turbine connected to a generator.
A biomass plant is composed of 3 parts:
.The boiler in which is burned fuel
.The engine room that produce electricity
Power lines for the transportation of electricity
Biomass
5 / recycling
At the exit of the turbine, the steam is again transformed into water through a condenser in which circulates cold water from the sea or a river. The water thus obtained is recovered and re-circulates in the boiler to begin another cycle.
3 / Electricity generation
Steam drives a turbine that drives a generator.
The generator produces the electricity.
1 / Burning
The biomass is burned in a combustion chamber, producing heat
2 / The steam production
On burning, biomass generate heat that will heat water in a boiler. The water turns into steam, sent under pressure to the turbine.
4 / Heat production
At the output of the turbine a part of the steam is used for heating

Conclusion
Today the use of fossil and nuclear energy is a topical issue , biomass appears to be a sustainable and positive solution . Research is ongoing and it is undeniable that certain processes such as biogas and biofuels are real solutions. However, it is equally important to realize that in biomass energy , some processes such as exploitation of wood represents a major environmental hazard that must find an alternative.
