Answer:
In my opinion, a reduction in our use of energy would not be a historical step backwards.
Explanation:
We already know that humanity's consumption of fossil fuels is wreaking havoc on the ecosystem.

Nonetheless, altering our behaviors in a significant sense has proven to be quite difficult. As a result, it is not impossible to reduce our energy use significantly, but we may take little efforts to change the way we create energy, such as using fossil fuels. Because fossil fuels are so detrimental to our environment, we should try to reduce its use, but not at the risk of improving our surroundings. There are several methods to change the way we utilize energy now into something more sustainable.
