Energy use is changing fast. The shift to renewable sources, however, needs to happen faster, not just in power generation but in heating, buildings and transport, to check the rise in global temperatures. Show Renewables could supply four-fifths of the world’s electricity by 2050, massively cutting carbon emissions and helping to mitigate climate change. But solar and wind power have to be fully integrated, with sustainable bioenergy providing another key part of the mix. All this means speeding up innovation in business and technology. Above it all, it means taking action to promote renewable energy today.
Featured Recent PublicationsHow Much Can renewable energy help climate change?Renewable power could cover up to four-fifths of global electricity supply by 2050 – drastically reducing carbon emissions and helping to mitigate climate change.
Can renewable energy reduce climate change?There is no path to protecting the climate without dramatically changing how we produce and use electricity: nearly 40% of US CO2 pollution comes from power plants burning fossil fuels. But we can turn things around. Renewable energy minimizes carbon pollution and has a much lower impact on our environment.
How much renewable energy do we need to stop climate change and how can we make this happen?Renewable energy makes economic sense
In comparison, about $4 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.
How much renewable energy is needed?Renewable Supply and Demand
About 11.2 percent of the energy consumed globally for heating, power, and transportation came from modern renewables in 2019 (i.e., biomass, geothermal, solar, hydro, wind, and biofuels), up from 8.7 percent a decade prior (see figure below).
