Common Renewable Energy Sources

Renewable energy sources are those that can be replenished naturally and are not depleted with use. Here are some of the most common renewable energy sources:

Solar Energy

• Energy obtained from the sun through the use of solar panels.

• Can be used to generate electricity or heat water.

• Clean and abundant source of energy.

Wind Energy

• Energy obtained from the wind through the use of wind turbines.

• Can be used to generate electricity.

• Clean and abundant source of energy.

Hydroelectric Energy

• Energy obtained from the movement of water through the use of hydro turbines.

• Can be used to generate electricity.

• Clean and abundant source of energy.

Geothermal Energy

• Energy obtained from the heat of the earth's core through the use of geothermal power plants.

• Can be used to generate electricity or heat buildings.

• Clean and abundant source of energy.

Biomass Energy

• Energy obtained from organic matter such as wood, crops, and waste.

• Can be used to generate electricity or heat buildings.

• Can be a sustainable source of energy if managed properly.

Common Non Renewable Energy Sources:

Non-renewable energy sources are those that cannot be replenished in a short period of time. These sources are finite and will eventually run out. Here are some of the most common non-renewable energy sources:

1. Fossil Fuels

• Fossil fuels are formed from the remains of dead plants and animals that have been buried for millions of years.

• The most common types of fossil fuels are coal, oil, and natural gas.

• Fossil fuels are used to generate electricity, power vehicles, and heat buildings.

2. Nuclear Energy

• Nuclear energy is produced by splitting atoms of uranium or plutonium in a process called nuclear fission.

• The energy released from nuclear fission is used to generate electricity.

• Nuclear energy is controversial due to the potential dangers of nuclear accidents and the disposal of radioactive waste.

Advantages of Renewable Energy

1. Renewable energy is sustainable and does not deplete natural resources.

2. It produces little to no greenhouse gas emissions, reducing the impact of climate change.

3. It is often cheaper in the long run than non-renewable energy sources.

4. It can be generated locally, reducing dependence on foreign sources of energy.

5. It creates jobs in the renewable energy industry.

Disadvantages of Renewable Energy

1. Renewable energy sources can be intermittent, meaning they are not always available.

2. The initial cost of installing renewable energy systems can be high.

3. Renewable energy systems can take up a lot of space, especially wind and solar farms.

4. Some renewable energy sources, such as hydroelectric power, can have negative environmental impacts.

5. Renewable energy sources can be affected by weather conditions, such as wind and cloud cover.

Disadvantages to non-renewable energy:

• Limited availability: Non-renewable energy sources such as fossil fuels are finite resources that will eventually run out.

• Environmental impact: The extraction, transportation, and burning of non-renewable energy sources can have negative impacts on the environment, including air and water pollution, habitat destruction, and climate change.

• Price volatility: The price of non-renewable energy sources can be unpredictable and subject to geopolitical events, making it difficult for businesses and consumers to plan for the future.

• Health risks: The use of non-renewable energy sources can have negative impacts on human health, including respiratory problems and other illnesses caused by air pollution.

Non renewable energy sources have the following advantages:

• Reliability

• Availability

• Affordability (in some cases)

• Established infrastructure for extraction and distribution
