renewable energy sources are unlimited.

MOST OF THEM ARE VERY GOOD FOR THE ENVIRONMENT, BECAUSE THEY DON'T CAUSE AIR POLLUTION, GLOBAL WARMING, HABITAT DESTRUCTION OR LOSS OF BIODIVERSITY.

solar energy

• One of the cleanest sources of energy.
• Not dangerous for the health
• Does not polute the air

solar energy

• Is only practical in very sunny climates
• Solar panels need a lot of space

pros

cons

wind energy

• Is very clean and renewable

• Only works in very windy places.
• It can damage wildlife habitats.
• It can threaten bird population.

pros

cons

water energy

• Does not cause any pollution
• Energy can be generated when needed.

• Wildlife habitats are destroyed when we build a dam.
• This can cause a loss of biodiversity in the area surrounding the dam.
• Droughts can affect the production of electricity

pros

cons

geothermal energy

• It's a very clean source of energy

• You only can use it in areas with volcanic activity
• Geothermal plnats have an environmental impact

pros

cons

• Is heat that comes from inside the Earth.

Biomass

• You are recycling waste products to create energy
• It's cheaper then fosil fuels

• Causes air pollution and contributes to global warming.

pros

cons

• Organic materials such as rests of wood and food waste.
• In power stations, they burn it to boil water.
• The steam (boiling water) moves a turbine and generates electricity
• We can also use it to heat our homes (pellets)
