Question

explain why it is important that we find alternative sources of energy rather than rely on coal or petroleum. Give short answer ​

Answer 1

Answer:

Using more renewable energy can lower the prices of and demand for natural gas and coal by increasing competition and diversifying our energy supplies. And an increased reliance on renewable energy can help protect consumers when fossil fuel prices spike.

Answer 2

Answer:

Alternative energy represents the clean energy source (does not pollute) that derives from a natural and renewable source of energy such as solar, wind, geothermal, waves, tides, waste, biomass, hydrogen and so on.

As the name suggests, alternative energy has appeared as an alternative to fossil fuels because fossil fuels are considered finite sources of energy and are polluting the environment.

Today, we start using alternative sources of energy like solar power, wind power, geothermal, biomass, hydro power, waste energy and so on, because these renewable energy sources are not polluting the environment and are helping us to reduce the level of greenhouse gas emissions in the atmosphere and to reduce climate change effects.

Of course, is not enough to generate clean energy from clean and renewable energy sources like the Sun, wind, water and biomass, we also need to reduce the level of CO2 in the atmosphere.

Green plants consume CO2, so they can be used as a green army that can help us reduce the level of CO2 in the atmosphere.

More trees mean less CO2 in the atmosphere, so instead of cutting the forests to be used in the industry, we need to plant the trees back in their place, and even to populate new areas with young trees and regenerate the forests.

There are more and more companies in the world that are getting revenues from renewable energy.

There are also a few controversies here because some consider hydropower and nuclear power as alternative energy sources (they are different than fossil fuels represented by coal, oil and gas), while others say that nuclear power produces nuclear waste that is harmful for the environment.

In terms of nuclear power we can consider as a renewable energy source of the future the energy produced by nuclear fusion.

ITER builds a tokamak fusion reactor in southern France.
