Because it is renewable by nature, using renewable energy is typically much more efficient than using fossil fuels. This means that, in contrast to fossil fuels, renewable energy sources usually do not require us to engage in risky or harmful activities in order to obtain the fuel.
Most renewable energy farms or plants can be established once and continue to produce energy effectively for decades. When you construct a wind turbine, it will provide electricity with very little upkeep; you won't need to keep locating new wind to power it. It will function very effectively provided it is constructed in a suitable place with regular wind access.
It's also important to note that many fuels produce energy inefficiently. For instance, coal only emits 29% of the energy that it originally contained. The energy produced by wind is 1,164 percent of its original worth. That's a really significant difference!
