Solar energy comes from sunlight and can be used to heat water, power vehicles and appliances, and even cook food. It is the most abundant energy resource on Earth as it can be found anywhere the sun shines. The largest solar plant is located in California's Mojave Desert and uses over 930,000 mirrors to convert sunlight into electricity. Wind turbines operate within a power range of 600 kW to 5 MW and produce more power as wind speed increases, with their long-term potential said to be 5 times total current global energy production. There are two main types of wind turbines: vertical axis and horizontal axis.
