Solar panels, wind turbines, and water dams in one place. This will help people use more renewable energy. But there will be more solar panels than wind turbines, and more wind turbines than water dams because dams like the Hoover Dam cost lots of money to build. Wind turbines are cheaper than those and solar panels are cheaper than wind turbines. We can also make biofuels in those places where there are solar panels, wind turbines, and water dams. This will help reduce the use of fossil fuels as our main source of energy, which is nonrenewable and is bad for our environment.-
