operations during a year is 22,352 tons, meaning that 0.2 grams of carbon dioxide are emitted each time
we do an internet search.

This is why we have to reduce the use of fossil fuels and use new, renewable energy. At present, the
most notable renewable energy sources are wind power and solar power. The growth of IT technology
has allowed solar farms to form intelligent power grids that optimize supply and demand. Solar power
has made it easier to supply electricity in the form of distributed power, and wind energy is even more
efficient than solar power. However, these two sources are affected by the weather, and the installation
processes are not eco-friendly. Another new renewable energy that can correct these flaws are fuel cells.
A fuel cell system is a high efficiency, eco-friendly technology which converts chemical energy generated

by the electrochemical reactions of
hydrogen and oxygen into electrical
energy. Fuel cell technology is
considered a next generation energy
source because it reduces energy
loss by producing electricity in a way
that is unlike preexisting generators.

The energy needed for the Fourth
Industrial Revolution is eco-friendly,
high-capacity, and highly-efficient energy. Continued research is needed to solve this energy problem,
and the development of new renewable energies will require attention and commitment as it can directly
affect our lives.
