In our modern world we need energy to almost everything we need electricity for our homes petrol for our transport and gas for our heaters but some forms of energy have a dangerous effect on the environment. They produce gases for example carbon dioxide witch stop heat leaving the earth . this means the planet is getting warmer
Sustainable energy comes from renewable resources. for example from the sun the wind and the sea we can all do something to be green already some people are using solar power to heat their homes and to save water you recycle water used for bathing and washing clothes you use this waste water for watering plants and trees
