Over the years, renewable energy has been the area of concentration for many scientists. Although, despite coming up with persuasive and practical technologies on renewable energy, the process of getting most people to change from the use of non-renewable energy has been quite difficult and slow.
As seen from the opinions and feedback by scientists on UK.collected.reviews, it has been discovered that renewable energy technologies have enabled cheap energy providers to create electricity, fuel, and heat from renewable sources.
Therefore, the use of more renewable energy can lower both the prices and demands for natural gas and coal, by increasing the competition and diversifying our energy supplies.
What are the needs for developing renewable energy technologies?
1. Less global warming
Human activity is said to have congested the atmosphere with carbon dioxide, and other global warming emissions. These gases tend to trap the heat, thereby causing a web of significant yet harmful impacts, such as frequent storms, droughts, increase in sea level, and maybe extinction. In different countries, about a certain percentage of global warming emission originates from the electricity sector. Some of them come from fossil fuels such as coal and natural gas. In contrast to this, most renewable energy sources barely produce global warming emission.
2. Improved public health
Air and water pollution emitted by fossil fuel such as coal and other natural gas plants can cause serious breathing problems, heart attacks, cancer, and in most cases death. These negative health impacts come from air and water pollution that clean energy doesn’t produce. Meanwhile, the use of solar, wind and hydroelectric systems can generate electricity without any form of pollution.
3. Jobs and other economic benefits
Unlike fossil fuel technology that is capital intensive and mechanized, renewable energy technology is more labour-intensive. For instance, solar panels would need humans to install them; wind farms would also need technicians to maintain them. This simply means that there would be more jobs for every unit of electricity that is generated from renewable energy.
4. Stable energy prices
Renewable energy technology provides affordable electricity across different countries, and it can also assist in stabilizing the price of energy soon. As much as renewable energy needs upfront investment to build, it can operate at a very minimum cost. This means that for most clean energy technologies, fuel is free, and as a result of this, there is a huge possibility that renewable energy would be stable in years to come.
5. Reliability and resilience
Renewable energies such as wind and solar energies are not prone to failure because they are spread out over a large geographical location, and are composed of different individuals wind turbines, or solar display. Even if there is a problem with a piece of equipment, the other systems can continue to function. While non-renewable energy depends on having enough water for cooling, this simply means that water scarcity or drought can cause a serious problem, thereby putting electricity generation at high risk.
The primary aim of renewable energies is to advance economic development, improve the access to energy, and mitigate climate change.
