- Transitioning to Renewable Energy: Renewable sources, such as, solar, wind, hydro, and geothermal power from fossil fuels reduces greenhouse gas emissions associated with electricity generation and decreases reliance on carbon-intensive energy sources. Another potential source for generating electricity is from nuclear energy rather than the combustion of fossil fuels.
Detailed Explanation
This strategy focuses on replacing fossil fuels with renewable sources of energy like solar, wind, or hydroelectric power. By doing this, we significantly lower emissions from electricity generation, which is a major contributor to greenhouse gases. The paragraph also mentions nuclear energy as another cleaner option compared to fossil fuels.
Examples & Analogies
Imagine replacing your gas stove with an electric stove powered by solar energy. Just like the gas stove releases emissions while cooking, the electric stove, when powered by solar, reduces carbon emissions, making your 'cooking practice' more eco-friendly.
