Costs and benefits to fossil fuel alternatives

The UK's energy mix has diversified in response to policies of reducing carbon emissions and improving energy security. 2020 was the UK's first year in which more electricity came from alternatives to fossil fuels than from non-renewables. Alternatives to fossil fuels can reduce carbon emissions, improve energy security and diversify the energy mix. Alternatives to fossil fuels include biofuels, wind, solar, HEP and future technologies such as hydrogen. Alternatives to fossil fuels have both benefits and costs.
