The third step is to switch to renewable energy sources as much as possible. Renewable energy sources, such as solar, wind, hydro, biomass, and geothermal, are cleaner, cheaper, and more abundant than fossil fuels. They also have lower social and environmental impacts, such as carbon emissions, water scarcity, and human rights violations. You can switch to renewable energy by choosing a green energy supplier, installing renewable energy systems on your premises, or participating in community energy projects. Switching to renewable energy not only reduces your greenhouse gas emissions, but also supports the transition to a low-carbon economy and society.
