Electricity demand will grow much faster than other types of energy in the next decades, according to a new report from the International Energy Agency (IEA). The report was released during climate talks in Brazil. It explains what changes are happening, when they may happen, where demand is increasing, and why this is important for many countries. The IEA says that renewable energy, especially solar power, is growing very quickly. It also says that coal and oil could reach their highest use before 2030. However, another possible future shows that oil and gas may still grow until 2050 because different countries have different energy policies. The report notes strong energy growth in India, Southeast Asia, Africa, Latin America, and China. It also says that about 730 million people still do not have electricity and that many people still use cooking methods that are unsafe for health and the environment.

The report describes how countries may deal with these problems. It says that more investment is needed for power grids, energy storage, and important minerals used in solar panels, electric cars, and wind turbines. The IEA also reports that data centers are using more energy, with investment expected to reach $580 billion this year. The outlook warns that slow action and weak policies may cause the world to pass the 1.5°C warming limit.
