Solar energy is a key renewable resource. This GCSE Geography quiz looks at how solar power works, its advantages, limitations, and role in reducing greenhouse gas emissions.

Reducing energy demands would reduce greenhouse gas emissions
|
Solar power is best in countries that have a lot of sunshine. Hot deserts would be the best place for solar power stations but there are political and technical issues that would need solving first

It is not cheap to set up at all, in fact it is expensive to install photovoltaic systems
|
Solar power will be available for as long as the Sun is there. The Sun will use up its fuel in about 5,000 billion years but the Earth will be destroyed long before that happens

Over the last fifty years, globalisation and industrialisation has led to a large increase in the greenhouse gases in the atmosphere and many governments believe that reducing their country's carbon footprint will be better for the planet
|
You could regard oil, coal and gas as renewable on that basis but it is a matter of the timescale - they take tens of millions of years to form and we are using up current stocks a lot faster than they will be formed, so, at some point in the future, there will be no more oil and coal for millions of years

The tubes that absorb the Sun's heat are painted black to make them more efficient
|
If the area is particularly attractive, locals may also think that such an installation would be an eyesore

Although solar energy is a renewable resource, the materials from which solar panels, tubing, photovoltaic cells and other components are not. Careful management, including recycling is necessary to ensure that solar energy is sustainable for as long as possible

A grant is a short term economic benefit although you could possibly argue that it is a long term benefit too as it means you pay less to start with and so it has a shorter payback time
