Welcome to class!
In today’s class, we will be talking about renewable and non-renewable energy. Enjoy the class!
Renewable and Non-Renewable Energy
What is renewable energy?
Renewable energy can be defined as an energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as rain, wind, sunlight, tides, waves, and thermal heat. Renewable energy often referred to as clean energy, comes from natural sources or processes that constantly replenished.
Examples of renewable energy include; sunshine, wind, rain, tides, thermal heat, waves, etc.
Uses of renewable energy
The following are the uses of energy;
- Water:
Water can also be used to gather electricity by hydroelectric power plants, which harness the flow of runoff water in rivers, streams and lakes. There is great potential to use hydroelectric power in urban areas, where there is a constant flow of water through municipal pipes.
- Wind:
A windmill is typically attached to a generator that is powered by its rotation: When the wind blows, its force turns the windmill. Wind energy was first used not to produce electricity, but to perform repetitive mechanical tasks, such as pump water from wells or to grind grain. Today, windmills can be used for a variety of situations, including when a small amount of power is needed. They can be used in most places, as they can be made any size.
- Solar panel:
Solar panels are used to collect solar energy and turn it into electricity, and more and more they are used in homes. You may already have a garden lantern that is powered by a solar panel. When used as a major power source, solar panels are often quite large and may be mounted on the roof of a home. The solar energy collected is converted to electricity and can be used and stored, as with purchased electricity. Solar panels can be used to charge batteries and perform smaller electric tasks as well.
What is non-renewable energy?
A non-renewable resource is a natural resource that cannot be readily replaced by natural means at a quick enough pace to keep up with consumption. Non-renewable comes from fossil fuel. Non-renewable resources are those found inside the earth
Examples of non-renewable energy:
- Coal
- Natural gas
- Crude oil
- Tar sand
- Uranium
- Fossil fuel
Uses of non-renewable energy
Non-renewable resources include crude oil, natural gas, coal, and uranium. These are all resources that are processed into products that can be used commercially.
