Chapter 15: Problem 1

Why is it important for renewable energy sources to replace fossil fuels? What are the prospects for getting it done?

Short Answer

Expert verified
Renewable energy sources should replace fossil fuels due to their sustainability, non-polluting nature, economic development potential, and to improve energy security. The prospects for this transition are promising due to significant advancements in technology and increased awareness about climate change. However, challenges remain due to the current heavy dependence on fossil fuels in the global energy system.

Step by step solution

01

Understanding Renewable Energy and Fossil Fuels

Renewable energy refers to energy from sources that naturally replenish themselves, like sunlight, wind, and geothermal heat. In contrast, fossil fuels, such as coal, oil and natural gas, are non-renewable as they take millions of years to form and reserves are being depleted much faster than new ones are being made. The combustion of fossil fuels produces greenhouse gases and other air pollutants as by-products that lead to global warming and climate change.
02

Why Should Renewable Energy Replace Fossil Fuels

They are several reasons why the use of renewable energy is becoming more important: They are sustainable and will not run out; They do not emit harmful greenhouse gases; They can provide a source of income for many developing countries; and they improve energy security for countries that lack domestic fossil fuel resources.
03

Prospects for Getting It Done

Advancements in technology have significantly reduced the cost of renewable energy, so much so that they are now price competitive with fossil fuels in many parts of the world. Increased awareness about climate change has also led to a greater demand for 'green' energy. However, the transition to a fully renewable energy system does face challenges, as it would require a complete transformation of the global energy system, which is currently heavily dependent on fossil fuels.
