GREENHOUSE EFFECT

DAMAGE CONTROL6

Reducing emissionsBy the year 2050 carbon dioxide emission will need to be cut by 50% to minimise global change to the environment.

To reduce emissions there must be an improvement in the energy effi ciency of cars, household electrical items and factories.

Options to reduce carbon dioxide emissions foreverCarbon capture: Capturing carbon from the burning of fossil fuels before it enters the atmosphere. The carbon dioxide could be frozen and stored deep underground or in a deep ocean.

Nuclear power: Produces heat energy which can be used to generate electricity or power large ships. However, it is still an expensive option and there is a problem with waste disposal.

Renewable energy: Any source of energy which is readily replenished or cannot be used up.

Hybrid cars are a more fuel effi cient alternative to normal petrol cars.

Nuclear power offers one solution to burning fossil fuels. However, it is not without its own environmental risks.

Biofuels: Traditionally things like wood and animal dung. A modern example is ethanol from sugar cane. Burning biofuels does emit carbon dioxide into the atmosphere. This carbon is recaptured when more plants are grown to replenish the biofuel supplies.

Sources of renewable energy

Hydro power: Rapidly fl owing water turns turbines to create electric energy.

Solar power: Solar panels capture light energy from the sun and convert it to electricity.

Wind power: Large windmills convert wind energy to electrical energy.

Geothermal energy: Water is pumped deep into the Earth to harness the heat energy of the Earth’s magma.

The use of fossil fuel alternatives will assist in reducing emissions.

People can take extra steps to be more energy effi cient by walking, riding or using public transport instead of driving.
