1. How have fossil fuels been formed?
2. When is a source of energy said to be a renewable source of energy?
Give two examples of such sources.
3. When is a source of energy said to be a non-renwable source of energy?
Give two examples of such sources.
4. How is coal used by powerhouses for generating electricity?
5. Why should efforts need to be made to reduce the use of fossil fuels?
Answers
Answer:
Explanation:
1 FOSSIL FUELS FORM. After millions of years underground, the compounds that make up plankton and plants turn into fossil fuels. Plankton decomposes into natural gas and oil, while plants become coal. Today, humans extract these resources through coal mining and the drilling of oil and gas wells on land and offshore.
2.Coal, natural gas and oil are all examples of renewable energy resources. When they are burned they release energy. Coal, natural gas and oil are also known as fossil fuels. Wind and solar energy are examples of renewable energy sources because they can be replaced.
3.Non-renewable energy comes from sources that will run out or will not be replenished in our lifetimes—or even in many, many lifetimes. Most non-renewable energy sources are fossil fuels: coal, petroleum, and natural gas. Carbon is the main element in fossil fuels
4.Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
5.Fossil fuel energy affects the environment and health due to the emissions and impact of mining practices. Reducing fossil fuel usage helps protect the limited supply of fossil fuels while decreasing the pollution produced. Fossil fuel conservation saves you money in many situations.

A renewable energy source means energy that is sustainable - something that can't run out, or is endless, like the sun.
Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs.
