The first step toward making renewable energy a reality is to understand what constitutes a renewable resource. Unlike traditional energy resources, which may take millions of years to form, renewable energy sources are replenishable. Solar power, for example, can always be generated, but the sun’s rays are not always optimal for production. Another example is biomass, which is an organic material. In the United States, biomass was the leading source of energy before fossil fuels were developed, but the use of biomass has increased since. Modern examples of biomass are biodiesel, ethanol, and other biofuels.
There are many benefits of renewable energy. During the past decade, renewable sources such as wind, geothermal steam, and solar electricity generated power homes and businesses. In addition, they have become valuable transportation fuels, including biodiesel and ethanol. These resources have many advantages and drawbacks, and can be used at various scales to meet various energy needs. Some renewable sources are better suited for certain geographical regions than others.
Solar energy is a natural renewable energy source, converting sunlight’s rays into trapped heat. This heat can then be used to sustain a chemical reaction and produce electricity. Photovoltaic solar panels use sunlight to produce electricity, while concentrating solar-thermal power uses concentrated solar-thermal power to store the energy from the sun. Unfortunately, solar energy does not occur all year long and its availability coincides with the peak energy demand. In this case, renewable energies are dependent on efficient battery storage.
Traditional renewable energy sources are biomass and solar energy. These fuels are the oldest sources of renewable energy. Humans have been using biomass as fire and fuel for hundreds of thousands of years. In ancient times, biomass for fire was used for cooking and heating. Today, geothermal energy is used to heat water for bathing and for space heating. However, while they may be the most environmentally-friendly, they also contribute to global warming. That is why they are considered sustainable resources.
The world is undergoing a transition away from traditional renewable energy. Increasing energy consumption in the United States will lead to a reduction in carbon emissions and a decrease in the overall amount of electricity used. During the last century, renewables accounted for only 5% of the total electricity supply in the United States. By 2040, this figure will increase to five percent of our total consumption. The increase in renewables is far greater than the growth in oil and coal.
The main drivers of renewable energy are businesses that want to create more sustainable environments. Companies that are committed to the environment and social responsibility will invest in renewable energy facilities and purchase certificates. The cost of solar and wind energy technologies have decreased dramatically over the past decade, and the newest technologies such as hydropower are now widely available at lower prices than ever. This trend is also driving down the cost of manufacturing. While the technology is still new, it is more affordable than ever before and is proving to be a reliable and economical way to power the world.
Historically, the primary sources of renewable energy were human labor, animal power, and water. Other sources of renewable energy included wind, water, and firewood. In modern times, the most common sources of renewable energy in the U.S. are hydropower, wind, and solar. These sources are cheaper and more diverse than traditional sources and will produce more electricity for us in the future. But there are several challenges. They require a higher level of investment.
While it is possible to develop renewable energy sources for power, traditional sources are outdated and unable to support our growing demands. In addition to fossil fuels, they are also environmentally destructive. In the United States, renewable energy will provide an estimated 5% of the country’s energy by 2020. As of 2016, this is a growing market with high returns. It is the only way to provide renewable energy. The only way to achieve this goal is to implement energy efficiency.
In 2020, renewables will account for around 5 percent of the total energy consumption in the U.S., compared to just under two percent today. Compared to fossil fuels, these sources do not produce CO2, which makes them carbon-neutral. This means they are the perfect alternative for all industries. While fossil fuels will not disappear anytime soon, renewable energy sources will remain a valuable source of energy for centuries to come. This is an important factor because renewable energy is carbon-neutral.
