Renewable energy sources play a big role in how we use electricity. Here are some important points to know:
Turning Sunlight into Electricity: Solar panels take sunlight and change it into electricity. They do this using special parts called photovoltaic cells. In 2021, solar energy made up about 10% of all the electricity produced around the world.
Storing Energy: Wind turbines create electricity too. This energy is often stored in batteries so we can use it later. Experts believe that the market for energy storage will grow to reach $546 billion by the year 2035.
Connecting to Power Grids: Renewable energy sources need to be connected to power grids to work properly. For example, in 2020, Germany got 42% of its electricity from renewable sources. This shows how much we rely on smart electrical systems to use energy efficiently.
