Power generation has been a hotly debated topic for decades, with the rise of technological advances and the growing demand for energy. Conventional sources of energy such as coal and nuclear power have been known to be reliable sources of power, but come with potential risks that cause concern for many. Renewable sources such as wind and solar are becoming increasingly popular, though they are typically more expensive and have lower power output. With so many options available, it can be difficult to decide which is the best way to produce power. Regardless of which method is selected we require power for our homes, phones, vehicles, trains and economy. And that demand won’t go away anytime soon.
