# Renewable Energy Sources and Climate Change Mitigation. “Renewable Energy Sources and Climate Change Mitigation”. Renewable energy sources have a large potential to displace emissions of greenhouse gases from the combustion of fossil fuels and thereby to mitigate climate change. If implemented properly, renewable energy sources can contribute to social and economic development, to energy access, to a secure and sustainable energy supply, and to a reduction of negative impacts of energy provision on the environment and human health. This Special Report on Renewable Energy Sources and Climate Change Mitigation (SRREN) impartially assesses the scientific literature on the potential role of renewable energy in the mitigation of climate change for policymakers, the private sector, academic researchers and civil society. It was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) to provide the world with a clear scientific view on the current state of knowledge on climate change and its potential environmental and socio-economic impacts.

Replacing fossil fuel-reliant power stations with renewable energy sources, such as wind and solar, is a vital part of stabilising climate change and achieving net zero carbon emissions. Professor Magda Titirici, Chair in Sustainable Energy Materials at Imperial College London, offers an introduction to renewable energy and the future of clean, green power in the UK. Major sources of renewable energy include solar, wind, hydroelectric, tidal, geothermal and biomass energy, which is derived from burning plant or animal matter and waste. Switching our reliance on fossil fuels to renewable energy sources that produce lower or no greenhouse gas emissions is critically important in tackling the climate crisis. One of the main benefits of most renewable energy sources is that they don’t release carbon dioxide or pollute the air when they’re used to produce electricity or heat. Wind energy is an important renewable resource for the UK. ## Can renewable energy replace fossil fuels in the UK? In 2020, 42% of the UK’s electricity came from renewable energy.

Electricity produced from wind (Figure 1), solar, or geothermal sources, biomass energy conversion systems, and increases resulting from modernization of hydroelectric systems (HMOD) generally are considered renewable energy. GHG Reduction Costs Although renewable energy systems produce little or no GHG emissions, the electricity produced by these systems typically costs more than electricity generated from fossil, hydroelectric, and/or nuclear power plants. Figure 2 reveals the range in generation costs (dollars per kilowatt hour) and GHG reduction costs (dollars per ton of carbon dioxide-equivalent) for HMOD, wood waste co-firing (with and without assuming methane reductions), landfill gas, and wind energy systems. Wind and solar energy systems avoid coal-based carbon dioxide emissions, but they have rather high capital costs and low capacity factors that make them less attractive for reducing GHG emissions at the present.

# How Climate Change Impacts Renewable Energy. Because renewable energy sources depend on the environment, both the supply of and demand for renewables are affected by climate impacts such as high heat, drought, altered precipitation patterns, flooding, extreme weather and wildfires. Geothermal energy, which depends on heat from the Earth’s interior, is the renewable energy source least affected by climate change impacts, but it provides only 0.4% of U.S. electricity. “But we need to think about how climate change will impact the energy system as a whole because, unfortunately, no electricity generating system is immune from the impacts of climate change.”. “Each energy-generating facility is impacted by climate change and each impact is different,” said Webb. While climate change poses risks to renewable energy facilities, fossil fuel systems are jeopardized by the same impacts, so the vulnerabilities of renewable energy should not be a reason to delay the transition to clean energy, which will reduce climate-related risks by reducing greenhouse gas emissions.

Renewable energy sources are all around us. Switching to clean sources of energy, such as wind and solar, helps address not only climate change but also air pollution and health. For every dollar invested, renewable energy creates three times as many jobs as the fossil fuel industry. The IEA estimates that the transition towards net-zero emissions will lead to an overall increase in energy sector jobs: while about 5 million jobs in fossil fuel production could be lost by 2030, an estimated 14 million new jobs would be created in clean energy, resulting in a net gain of 9 million jobs. In 2024, $2 trillion went into clean energy – $800 billion more than fossil fuels and up almost 70 per cent in ten years. In comparison, about $4.5 trillion a year needs to be invested in renewable energy until 2030 – including investments in technology and infrastructure – to allow us to reach net-zero emissions by 2050. ### What is renewable energy?

# Renewable Energy Is Key to Fighting Climate Change. Renewable energy is one of the most effective tools we have in the fight against climate change, and there is every reason to believe it will succeed. A recent New York Times column seems to imply that renewable energy investments set back efforts to address climate change—nothing could be further from the truth. In the longer term, the U.S. Environmental Protection Agency’s Clean Power Plan to establish the first national limits on carbon pollution from power plants will continue to drive renewable energy growth. A recent report from the Department of Energy and Lawrence Berkeley National (LBNL) Laboratory found that renewable portfolio standards—state policies that mandate that a specific amount of the state’s electricity comes from renewables—provide a wide range of economic, health, and climate benefits. Much is said about the need to adapt the electric grid to the variability associated with integrating renewable energy into our electricity mix. Renewable energy is already helping address climate change.
