    How Solar Power Is Set to Become the New King of Electricity

    Published on

    Solar power is not only a key solution for climate change, but also an unstoppable force in the global energy market. According to a recent study, solar energy will become the dominant source of electricity generation by 2050, even without more ambitious climate policies. The study, conducted by the International Energy Agency (IEA) and the International Renewable Energy Agency (IRENA), attributes this remarkable trend to the rapid decline in the cost of solar plants and batteries, and the fast construction of solar farms.

    The study projects that solar photovoltaic (PV) plants will account for 43% of global electricity generation by 2050, followed by wind (32%) and fossil fuels (11%). This means that solar power will surpass coal, gas and nuclear as the main source of electricity in the world. The study also estimates that solar energy can reduce greenhouse gas emissions by 60% by 2050, compared to the current levels.

    Solar power is not just good for the environment, but also for people. Solar panels can sequester more carbon dioxide per acre than trees, and much more than corn ethanol, according to a study by Columbia University. Solar power also creates jobs, stimulates growth, and improves energy security. “Solar power is not just a key solution for climate change. It is also an important driver of economic development,” said Francesco La Camera, Director-General of IRENA.

    Solar power also has a minimal impact on water resources, land use, wildlife and human health, compared to fossil fuels. A study by Yale University found that wind and solar power have low life-cycle emissions, meaning that the emissions from their construction, operation and decommissioning are much lower than those from coal, gas and oil. “Wind and solar power are now mainstream options in the power sector. They not only offer substantial benefits for our climate, but also have a minimal impact on water resources, land use, wildlife and human health,” said Professor Ken Caldeira, Senior Scientist at the Carnegie Institution for Science.

    The world needs a massive amount of clean energy to meet its climate goals. The good news is that solar power is abundant, inexhaustible and increasingly affordable. The bad news is that we are not deploying it fast enough. The study warns that more policy support and investment are needed to accelerate the transition to a low-carbon economy.

    Solar power is set to become the new king of electricity, but it needs our help to reach its full potential. By choosing solar over fossil fuels, we can make a difference for our planet and our future.
