Question

explain briefly why is an acute need of the search for alternative source of energy on the earth?​

Answer 1

Answer:

If all homes used best insulation, low energy products and switched them off when not using them. Then they would stay warmer in winter with minimum heating and cooler in summer with minimum cooling.

Not only would the bill payers be richer but the suppliers would need to generate less. (Less profits, suprisingly they are not keen)

In addition, if the electricity, gas etc. Was from renewable sources, then global warming would be minimised.

Alternative sources need to remove energy from the environment, so that as it is used, it is returned. (But does not add to the total energy)

This means solar, wind, hydroelectric, tidal.

Using heat pumps as air sources or ground source heating in combination with renewables can help to recycle heat energy.

Answer 2

Answer:

If we continue to use fossil fuels, we may increase the temperature of the planet in ways that will harm us and our entire ecosystem. They will eventually run out, even as the population of Earth grows. For both these reasons, we need to find other sources of energy that do not emit carbon dioxide when used
