y7 energy

• energy creates electricity
• non renewable is coal, oil, gas and nuculear fuel
• coal is made up of compressed plant material
• fossil fuels are non-renewable sources of energy that have been formed over millions of years from the remains of plants and animals
• renewable is wind turbines, hydropower, solar panels and biomass- can be made as quickly as it's used
• energy stores- chemical, kinetic, gravitational potential, elastic potential, nuclear, thermal, nuclear
• energy transfers- forces, heat, electricity, light waves and sound waves
• gravitational potential energy - height above ground level
• chemical energy- stored in substances like food or petrol
• kinetic energy- moving objects store this type of energy
• elastic potential energy- when an object is stretched or compressed
• kinetic energy- moving objects
• gravitational potential energy- when an object has height above ground level
• gravitational potential energy to kinetic energy- high things going to low things
• Renewable energy- can be used more than once
• non - renewable energy- can only be used once
• fossil fuels are a gas that when they are burned it adds to the greenhouse affect. that gas is called carbon dioxide
• the name of electricity generation using hot rock underground to make steam and power a turbine is called geothermal energy
