Non-renewable energy is energy from fossil fuels such as coal, crude oil, natural gas, and uranium. …

Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods of time.

Examples of non-renewable energy sources are fossil fuels (coal, oil and natural gas) and nuclear fuels. Burning of fossil fuels releases greenhouse gases into our atmosphere. Renewable energy sources can be recycled or reused. Examples of renewable energy sources are wind, hydropower, solar power and biofuels.

Few examples of renewable energy are sunlight, water, wind, tides, geothermal heat, and biomass. The energy that is provided by renewable energy resources is used in 5 important areas such as air and water cooling/heating, electricity generation, the rural sector, and transportation.

What Is Renewable Energy? Renewable energy, often referred to as clean energy, comes from natural sources or processes that are constantly replenished. For example, sunlight or wind keep shining and blowing, even if their availability depends on time and weather.

Renewable energy sources, such as solar and wind power, provide a viable alternative to fossil fuels. And as the name suggests, these sources are renewable and won’t run out. Not only that, but they are also more environmentally friendly, producing little or no CO₂ when generating electricity.

Different Sources of Energy

• Solar Energy. The primary source of energy is the sun.
• Wind Energy. Wind power is becoming more and more common.
• Geothermal Energy. Source: Canva.
• Hydrogen Energy.
• Tidal Energy.
• Wave Energy.
• Hydroelectric Energy.
• Biomass Energy.

The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.

It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
