Renewable Energy
Renewable energy is energy produced from resources that are replenishable and that do not damage the Earth. Examples of renewable sources include solar power, wind energy, geothermal heat, and biomass. These resources can be used to produce power anytime the weather permits. They are also referred to as clean energy because they do not pose any environmental harm.
In addition to being free, renewable sources are more cost-effective than fossil fuels, which need to be collected and refined and transformed into usable forms. The downside of renewable energy is its cost, but it can be worth the investment in the long run. If you are concerned about global warming, renewable sources may be a good choice.
According to the International Energy Agency, renewable sources make up nearly half of all electricity produced in the world. In 2010, hydropower provided 77% of green power. However, that percentage has dropped to around 45% since then. This is because some forms of hydropower are not particularly environment-friendly. Solar and wind power, on the other hand, have seen a sharp increase in capacity since 2010.
The use of renewable energies dates back to ancient times. Waterwheels and windmills were invented to convert the energy produced by moving water into mechanical energy. These structures dotted the landscape of Europe and the Netherlands. Nowadays, modern wind turbines provide usable electricity and can power whole villages. The development of these technologies made it possible for many nations to utilize these resources for their energy needs.
What is Renewable Energy?
The transition to sustainable energy is not an easy task. While some renewable solutions are better than others, they cannot be used in every situation. Besides, the environment and the climate in your area will also play a huge role in how effective they are. And renewable sources can become unsustainable if they are used excessively. So, if you are interested in using renewable energy, you need to think about these factors before making a decision.
why to invest in renewable energy
Biofuel is energy produced by burning organic matter, called biomass. Biomass sources include trees, forestry, and food waste. The combustion of biomass results in carbon dioxide emissions, which are not good for the environment. On the other hand, biofuel is renewable because it can be grown again. This means that it can help absorb carbon emissions. Fossil fuels, on the other hand, are non-renewable.
reasons to invest in renewable energy
Solar energy is another renewable energy source. The sunlight sends more energy to the earth in an hour than the entire human population uses in a year. Photovoltaic solar panel cells can harness this solar energy and produce electricity. Concentrated solar power units, meanwhile, use solar heat to produce electricity and heat.
Biomass energy comes from plants, animals, and even garbage. When burned, biomass generates heat which is used to power a steam turbine. This process also creates electricity. However, biomass is dirty energy because it produces more carbon than fossil fuels and has negative impacts on biodiversity. However, some forms of biomass are low-carbon.
