Renewable Energy

renewable energy

Renewable technologies use natural energy to make electricity. Fuel sources include wind, wave, marine, hydro, biomass and solar. It is also made using sources of natural energy that are quickly replaced, such as biomass.

Renewables produce 7% of the UK’s electricity, and EU targets mean that this is likely to increase to 30% by 2020. From 2020, renewable energy will continue to be an important part of the strategy to reduce carbon emissions. To achieve this, a range of technologies will need to be used, such as onshore and offshore wind farms, biomass power stations or hydropower systems

Support schemes for renewable energy

In the UK there are several schemes that provide financial support for renewable energy. This is because some renewable technologies are more expensive to build than conventional technologies as they are newer and more innovative.

The Renewable Obligation (RO) is intended to encourage renewable electricity generation for large scale installations. It requires suppliers to source an ever increasing amount of the electricity from renewable sources. The RO rewards renewable output over the lifetime of a project.

The Feed-in Tariff (FiT) is designed to support small scale renewable installations up to 5MW. Through FiTs, generators are paid a tariff for every unit of electricity they produce. Any electricity not used on site can also be sold back into the Grid, and generators are paid extra to do this. Find out more about the FiT scheme at Department of Energy and Climate Change’s website.

A new scheme to support renewables and other low carbon technologies is currently being developed through Electricity Market Reform. The scheme will be called a Feed in Tariff with a Contract for Difference (CfD).

Solar PV

Solar photovoltaics are panels that convert the rays of the sun into energy. Solar PV makes a small contribution to our electricity supply, but this technology has become more popular in recent years.

Wind Power

The UK is well placed to develop wind power, with some of the best conditions in Europe and high average wind speeds. Both onshore and offshore wind farms are an important part of where the UK sources its energy and will play an increasingly larger role in the future.

Biomass

Biomass can be sourced from any living substance as well as from material such as biodegradable waste, food waste and animal manure. Biomass can be burnt in thermal power and heat generation. It can also be used in the anaerobic digestion process, making a bio-gas that can be burnt in electricity or heat generation. This gas can also be refined to become methane and injected into the gas grid.
