What is biofuel?
A non-renewable energy source created from either a plant product or animal dung
A renewable energy source created from either a plant product or animal dung
A fuel drilled from the ground
Biofuels are always gases
An electric generator produces an electromotive force (e.m.f.) of 200 V and produces a current of 3.0 A in a circuit.

How do solar panels transform energy from the sun?
Energy transferred by the light is absorbed by photovoltaic cells to generate electricity
Energy transferred by the light heats water increasing its store of thermal energy
Light passes right through the solar panel and into wires as electricity
Energy transferred by the light heats water, to turn a turbine, which generates electricity
Select two correct statements about tidal power:
Tidal power stations can be very expensive to set up
Tidal power is not used in the UK
Tidal energy will run out
The tide is used to rotate turbines to generate electricity
How do wind turbines generate electricity?
The blades spin to heat water, create steam, which turns a turbine, and produces electricity
The National Grid spins the turbines to transfer electricity to homes
Wind turbines do not generate electricity, they heat water
The blades of the wind turbine are moved by the wind, which turns a generator inside it and generates electricity
What is the greenhouse effect?
As we burn more fossil fuels, we build more greenhouses
Greenhouse gases such as carbon dioxide and methane in the earth's atmosphere absorb infra red radiation increasing the average temperature of the earth
Emissions from the burning of fossil fuels cause the sun to be hotter over time, adding to climate change
Greenhouse gases such as oxygen and nitrogen in the earth's atmosphere absorb infra red radiation increasing the average temperature of the earth
What is carbon capture ?
Trapping fossil fuels to stop them being burned and polluting the atmosphere
A computer system to work out how much carbon dioxide is produced by coal fuelled power stations
The capture of harmful carbon dioxide emissions for safe storage deep underground

Active solar design
Examples include solar ovens and green roofs:
Solar energy
Wind energy
Geothermal energy
Passive solar design
Active solar design
Which aspects of renewable energy electricity generation require updating the electricity transmission grid?
(I) Electricity generators are located in numerous, remote locations
(II) There is a need to transport electricity long distances
(III) There are storage problems due to the unpredictable nature of some renewables
I and II, only
I and III, only
II and III, only
III, only
I, II, and III
Which of the following is a reason why hybrid electric vehicles use less fossil fuel per mile traveled than a typical internal combustion engine vehicle uses?
Hybrid electric vehicles don’t burn fossil fuels; they run on electric energy
Hybrid vehicles are powered by the Sun using rooftop photovoltaic panels
When the brakes are applied in hybrid electric vehicles, kinetic energy is converted into electric energy to charge the batteries that assist the electric motor
Batteries in hybrid electric vehicles can be charged in the driveway overnight, when rates for electricity usage are typically low
The engines in hybrid electric vehicles are powered by biofuels made from genetically modified corn
A major limitation of using photovoltaic cells to generate electricity is that they:
Do not produce as much CO2 as other energy sources do
Do not produce as much electricity on cloudy days
Have no moving parts
Present a danger to birds and bats
Cannot be connected to the electric grid
How do solar cells transform energy from the sun?
Energy transferred by the light is absorbed by photovoltaic cells to generate electricity
Energy transferred by the light heats water increasing its store of thermal energy
Light passes right through the solar panel and into wires as electricity
Energy transferred by the light heats water, to turn a turbine, which generates electricity
