Types of energy resource

• Fuel: burnt to make thermal energy, makes steam, turns turbine
• Wave energy: generators driven by up and down motion of waves at sea.
• Tidal energy: dam built where river meets sea, lake fills when tides comes in & empties when tide goes out; water flow runs generator
• Hydroelectric: river & rain fill up lake behind dam, water released, turns turbine generator
• Geothermal: water pumped down to hot rocks rising as steam
• Nuclear fission: uranium atoms split by shooting neutrons at them
• Wind: windmills are moved by the breeze.
• Solar cells/ photovoltaic cells: made of materials that deliver electrical current when it absorbs light
