While fossil fuels have a long history of human use, we are moving towards renewable resources for our energy needs. Renewable energy sources include wind and solar energy, wood, and water. Although fossil fuels are expensive, they are limited and cannot replace the natural resources we use today. Renewable resources will soon replace fossil fuels, but we can’t turn back the clock on our current use of fossil fuels. Let’s take a closer look at some of the most popular sources of renewable energy today.
Hydropower uses water to create electricity. It is derived from the starch in corn kernels, but can also be made from sugar cane, wheat straw, and switchgrass. This colorless fluid is produced through photosynthesis. It is also known as biofuel. Regardless of how it’s produced, it’s a renewable resource that can power cars. Renewable energy resources have several other uses, but are most common for powering cars.
Geothermal energy harnesses heat from the earth to produce electricity. Wind energy, on the other hand, comes from uneven temperatures on the earth’s surface. Windmills spin and push energy into a generator. It has become one of the fastest-growing sources of electricity in recent years, rising from practically non-existent in the 1990s to nearly 7% of the world’s electricity in 2019.
Renewable energy development is similar to that of traditional hydroelectric, geothermal, biomass, and solar energy. This development process begins with reconnaissance, exploration, and visual observation of the land and resources in question. This initial work does not alter the present surface use of the land. But the process does require some investment in production equipment, which affects the installed cost and per-kilowatt-hour cost of delivered power. In addition to the environmental benefits, renewable energy also has major economic benefits.
While forestry and other natural resource management activities provide a valuable source of wood, other sources of renewable resources include wind and solar energy. These resources are non-food and energy crops that we need to survive. Renewable plants also include a variety of lubricants, textiles, and bioplastics. Starch and sugar also provide ethanol. Technical fat, fur, and animal derived products are also renewable resources. It is important to know that a renewable resource will not disappear in your lifetime. It will return in the future.
Energy produced from renewable resources is more abundant, less polluting, and better for the environment. Many of these sources, such as the sun, wind, and hydropower, can be used to generate electricity and heat. Photovoltaic systems are another way to convert sunlight into electricity. They can also convert direct sunlight into hot water. Renewable energy is a growing industry for electricity generation, which DOE is helping the country make. The future of our energy supply is dependent on it.
When you consider renewable resources, you can make the most of what’s on earth. The sun, wind, and water, for example, are all renewable and will replenish themselves as time goes by. Wind and solar energy are excellent examples of renewable resources. In addition to being abundant and cheap, solar energy and wind energy are both environmentally friendly and largely affordable. They can even be used to power homes. With a growing population and growing need for more energy, the world can only benefit from renewable resources.
