Answer:

The energy source that powers my home is gotten from burning of fossil fuels.

No! I do not like this energy source.

I personally would prefer solar source of electricity

Explanation:

Fossil fuels are fuels gotten from the decomposition of dead organisms over time, under intense heat and pressure. They are usually found buried beneath the earth's crust where they have been formed and trapped.

Most electricity generating stations generate electricity by burning fossil fuels like natural gas and gasoline to generate electricity. The problem with fossil fuels are the various part that they play in increasing carbon footprints in the atmosphere. The excess carbon in the atmosphere has been a major contributor to the global warming of planet Earth.

My preference for solar energy source is first due to its abundance unlike the fossil fuels that are already diminishing in storage beneath the earth's crust. Also, solar energy is a clean source of energy that does not leave any damage on earth from its use. It also promises to be a cheap source of power in the future with advances in solar technologies.
