Energy… The sun is our nearest Star… Photovoltaic power station Life on Earth depends totally on the sun Food for Plants Herbivorous carnivorus Decomposition & Fossilization Thermal energy warms Sunlight Water Lights and Heats the earth Chlorophill photosynthesis The water cycle O2 is used by all living beings to Produce energy Oil-Coal-Methane Air Earth Wind Wind power staions Energy Can be… Non-renewable energy sources Energy can be nonrenewable when it runs out. It cannot be replenished. Methane-coal-oiluranium Renewable energy sources Energy can be renewable when we can use it for ever and it cannot be used up. It can be replenished. Solar energy-windThermal energy-water Biomass-geothermal hub blades generator shaft Wind blows past the blades The blades rotate around a hub The hub is connected to a shaft inside the head. The rotanting shaft powers a generator to convert the energy into elecricity Electricity is sent via pylons and cables to homes around the couyntry. The Gheothermal energy is a another renewable Energy.This energy develops the stream from the geyers. Rainwater seeps ground E-ON Centrale di Fiume Santo Fiume Santo covers an area of 132 hectares, the plant group has a nominal installed capacity of 1040 MW (about 40% of energy generated in Sardinia).
