Generating Electricity

How is energy produced in a fossil fuel power station? The fossil fuel is burnt to heat up water, turning it into steam which then turns a turbine. The turbine is attached to a generator which produces electrical energy.
What is an advantage of a gas-fired power station instead of another type of power station? Gas-fired power stations have a short start up time and can be switched on very quickly.
What is the definition of a biofuel? A biofuel is any fuel obtained from a living or recently living organism.
Name two advantages of biofuels 1. It is a renewable source of energy because the species it is obtained from will not die out. 2. It's carbon neutral because the carbon it takes in from photosynthesis balances out the carbon produced from combustion.
How do nuclear power stations work? They use nuclear fission to heat a coolant liquid that then heats water into steam to rotate a turbine.
Name four sources of energy using wind and water and explain what they are Wind Power (Wind turns a turbine), Hydroelectric Power (Rainwater or reservoir running down a hill turns a turbine), Tidal Power (high tides are trapped behind a barrier and released through to turn turbines), Wave Power (waves turn a turbine on a float)
What's the difference between solar cells and solar panels? Solar cells convert light energy into electrical energy whereas solar panels convert light energy into heat energy.
What is CCS? Carbon Capture and Storage is a method of stopping CO2 emissions from fossil fuel power stations.
Why is it good to have high voltage electricity passed along the National Grid? A high voltage causes the current to decrease. The current is the aspect that heats up the wire and causes energy to be wasted as heat so the lower the current, the less energy is wasted.
