what is renewable energy?
Renewable energy refers to energy that is continuously replenished through the earth's natural cycle in a relatively short period of time, such as wind energy, solar energy, water energy, biomass energy, geothermal energy, ocean energy and other non-fossil energy sources. It is harmless or has minimal harm to the environment, its resources are widely distributed, and it is suitable for local development and utilization. Using renewable energy is what ITEHIL has been doing. From our solar panels to solar fans, ITEHIL has always embodied sustainable lifestyles in its products.
The importance of using renewable energy
I found an article in the 2019 issue 5 of World Environment Magazine, titled "When fossil fuels run out, what then". It describes that at the current rate that human society consumes energy, our fossil fuels will be exhausted within a few decades. Among them, oil will be used up after 2052 (about 30 years later), natural gas will be used up after 2060 (about 40 years later), and coal resources will last until 2090 (about 70 years later).
Whether the above data is accurate or not is not mentioned for now, but we need to know that the formation of fossil fuels takes hundreds of millions of years, and the rate of generation is compared with the rate of use today, so the possibility of resource depletion is very high. Therefore, in order to cope with possible energy crises in the future, the development of renewable energy must be planned in advance. At the same time, renewable energy also has many benefits.
Benefits of using renewable energy
1. They have less impact on the environment. Fossil fuels produce greenhouse gas emissions such as carbon dioxide when burned. Renewable energy can reduce a large amount of greenhouse gas emissions and help alleviate global climate change problems. According to the International Energy Agency, the use of renewable energy can reduce global carbon dioxide emissions by approximately 3 billion tons per year.
2. Better health. According to the World Health Organization (WHO), about 99% of the world’s people breathe air that exceeds air quality limits, threatening their health. More than 13 million people die globally every year due to avoidable causes, including air pollution. caused by environmental reasons. Particulate matter and nitrogen dioxide, which are harmful to health, come primarily from the burning of fossil fuels. Therefore, switching to clean energy will not only help combat climate change, but also help solve air pollution and health problems.
3. Renewable energy will be cheaper in the future. The cost of solar power fell by 85% between 2010 and 2020. The cost of onshore and offshore wind energy has dropped by 56% and 48% respectively. It can be expected that in the future, as technology advances, renewable energy will be a cheaper option than fossil energy.
