Explanation:
Protecting the environment means improving its sustainability and reducing pollution to the barest minimal. This utterly means terminating every activity that contributes to pollution in the environment, including the source of energy. The most widely used source of energy is the non-renewable source e.g. coal, fuel, etc.
These source of energy, however, release pollutants in form of greenhouse gases, into the environment. One way to eliminate the use of non-renewable source of energy is to adopt the use of renewable sources e.g. solar energy, wind etc. However, one major setback to doing this is the high production cost involved.
Although these sources of energy (renewable) are referred to as green or clean, but they have really expensive startup costs and are unaffordable most times.
