Solar energy is a renewable source of energy that is produced by harnessing the power of the sun. It is a clean and sustainable source of energy that has become increasingly popular in recent years, particularly in the United Kingdom, where the government has set a target of generating 15% of the country’s energy from renewable sources by 2020.
Solar energy can be generated in two ways: by using photovoltaic (PV) cells or by using concentrated solar power (CSP) systems. PV cells are made from layers of silicon and other materials that convert sunlight into electricity. CSP systems use mirrors or lenses to concentrate sunlight onto a small area, which then heats up a fluid to produce steam. The steam is then used to turn a turbine, which generates electricity.
The United Kingdom has a relatively low level of solar energy potential compared to other countries, due to its position in the northern hemisphere and its often cloudy weather. However, with advances in technology and a growing interest in renewable energy, solar power is becoming an increasingly viable option for the UK.
One of the main benefits of solar energy is that it is a clean and sustainable source of energy. Unlike fossil fuels, which produce harmful greenhouse gases when burned, solar energy produces no emissions or pollutants. This means that it has a much lower impact on the environment and can help to reduce the UK’s carbon footprint.
Solar energy also has the potential to provide a significant amount of energy to the UK. In 2019, solar power generated 12.9 TWh of electricity in the UK, accounting for 4.8% of the country’s total electricity generation. This is a significant increase from just a few years ago, when solar power accounted for less than 1% of the UK’s electricity generation.
Another benefit of solar energy is that it can be generated on a small scale, making it accessible to individuals and communities. This is particularly important in rural areas and in developing countries, where access to electricity is limited. By installing solar panels on homes and buildings, individuals can generate their own electricity and reduce their reliance on the grid.
However, there are also challenges associated with solar energy. One of the main challenges is that it is an intermittent source of energy, meaning that it is only available when the sun is shining. This can make it difficult to rely on as a primary source of energy, particularly in countries with a high demand for energy.
Another challenge is the cost of installing solar panels. While the cost of solar panels has decreased significantly in recent years, they can still be expensive to install, particularly for individuals and communities with limited financial resources.
Despite these challenges, solar energy has the potential to play a significant role in the UK’s energy mix. With advances in technology and a growing interest in renewable energy, solar power is becoming an increasingly viable option for the UK. By harnessing the power of the sun, the UK can reduce its reliance on fossil fuels and move towards a cleaner, more sustainable energy future.
