They have chemical energy stored within them. About three-quarters of the electricity generated in the UK comes from power stations fuelled by fossil fuels.
This diagram shows an energy transfer diagram for the generation of electricity from a fossil fuel such as coal. Carbon capture and storage is a way to prevent carbon dioxide building up in the atmosphere.
The output of solar panels is reliant on the strength of the sunshine, which depends on a number of different factors, such as the time of day and the amount of cloud cover as well as the amount of dust on the panels. Another problem is that there might not be enough space or public willingness to accommodate the vast number of turbines or panels required to produce enough electricity. This is due to the fact that energy from the wind or the sun is diffuse, meaning that very significant amounts of land are required in order to generate a significant quantity of electricity.
Because electricity cannot be easily stored, renewables have to be backed up by other forms of electricity generation. The largest batteries cannot operate for days, let alone the weeks that would be required to back up renewables in order to ensure the supply of round-the-clock electricity.
In order to ensure a steady supply of electricity, gas plants are increasingly providing backup services to renewables electricity. Natural gas plants emit large amounts of carbon dioxide during operation, and significant amounts of methane are often released during the extraction and transport of gas, both of which contribute to climate change. A biomass plant operates in a very similar way to gas- and coal-fired power plants. In , biomass generated 2. Biomass production can require a lot of energy, both in terms of production of biomass itself and in terms of transport.
Due to this, the energy required can be greater than the energy value in the final fuel, and the greenhouse gas emissions can be as high, or even greater, than those from equivalent fossil fuels. Additionally, it can take more than years for the emitted carbon dioxide to be absorbed, which leads to a short-term emissions increase.
Other environmental impacts related to land use and ecological sustainability can be considerable. Additionally, as with coal, the use of biomass can contribute to air pollution, and thus has negative health impacts for populations local to biomass plants. Electricity is growing in importance.
If we are to address climate change and reduce air pollution, we will need to increase the use of all low-carbon energy sources, of which nuclear is an important part. This would mean that nuclear generation would have to triple globally by then.
In order to drastically reduce the levels of fossil fuels, nuclear and renewables need to work together to secure a reliable, affordable and clean future energy supply. Today, fossil fuel industries drill or mine for these energy sources, burn them to produce electricity, or refine them for use as fuel for heating or transportation. Over the past 20 years, nearly three-fourths of human-caused emissions came from the burning of fossil fuels.
