2. crude oil Coal. It is found in layers, veins, coal seams natural gas. It is a natural mixture of gases, primarily methane Fossil fuels: they come from geologic formations beneath the Earth

3. Directly, by using photovoltaics Solar power. Conversion of sunlight into electricity Indirectly, using concentrated solar power, that uses lenses or mirrors to focus sunlight

4. Wind power. Conversion of wind energy by using wind turbines to make electricity Offshore wind power. To harness better wind speeds available offshore compared to on land

5. Biofuels: Bioethanol, alcohol made by fermentation from carbohydrates, and biodiesel, obtained from vegetable oils or animal fats

6. Hydropower. Energy of falling water: It comes from potential energy, driving water to a turbine
