Case Studies: Successful Renewable Energy Projects

Many farmers and agribusinesses have found success by using renewable energy. These examples show how renewable energy can save money, protect the environment, and increase crop yields.

Solar Farms in California

California is a leader in solar energy for farming. The agrivoltaics concept combines solar panels with crops. Since 2011, over 500 projects have been started in China, including crops, livestock, and greenhouses.

In Hainan, China, solar greenhouses have a 2 GW capacity. They supply vegetables to 3 million people all year. This shows how renewable energy can make food more secure and sustainable.

Wind-Driven Irrigation in Iowa

Iowa’s vast farmland and steady winds make it ideal for wind-driven irrigation. This method uses wind to pump water, saving money and resources.

In Inner Mongolia, a 1 MW solar project was started with government and private help. It makes money by selling electricity, giving herders a 20% return. Inner Mongolia’s high solar energy makes it perfect for solar projects.
