GUEST POST: Renewable Energy: Facts and Mythology

This audio was created using Microsoft Azure Speech Services

The demand for electrical engineers is on the rise in a nontraditional niche: renewable energy. With increasing concern about global warming, organizations are seeking cost-effective and ecofriendly solutions to generating power. Electrical engineers are the experts behind smooth-running electrical systems. But common myths and intense lobbying have hampered renewable energy development in some areas. In fact, anti-alternative energy rhetoric has placed a “chilling effect” on electrical engineers seeking to pursue work in alternative energy fields.

Myth #1: Renewable energy is too expensive

One of the top renewable energy myths is that it’s too expensive. Coal-generated electricity runs as low as 3 cents per kWh, according to research published in the Journal of Environmental Studies and Sciences. But the hidden costs of energy produced by coal including pollution, carbon dioxide emissions, and CFC toxic material, which gear up global warming, are not included in this cost calculation. By contrast, solar and renewable energy methods, although they generate a higher cost per kWh, do not emit toxins. Therefore, they have no hidden costs, making them cheaper than they initially appear and more stable in price.

Myth #2: Renewable energy isn’t sustainable

Another renewable energy myth is that it’s not sustainable. Sunshine isn’t constant in areas of extreme winter weather. The variability of solar power is one of the most problematic points for sustainability. However, smart electrical engineering combined with minimal backup power from electrical grid operators can solve this problem. Investment in transmission lines has picked up speed, providing wider power access.

Myth #3: Renewable energy isn’t good for the environment

This is probably the most prominent myth about renewable energy. Many believe, for instance, that wind mills can harm birds. However, appropriate planning based on migratory patterns can alleviate this concern. In addition, noise pollution from wind mills is an issue for some, but the same can be said for the toxins and waste that coal and nuclear plants produce.

Where does that leave electrical engineers?

The demand for electrical engineers in the renewable energy world will continue to rise as developed countries like the U.S. and Japan aim to increase renewable energy production. Since electrical engineers excel at making quality power system designs that can improve business operations and curb costs, their role is essential in overcoming the challenges inherent in generating renewable energy.

  • I was reading the article, and thought ‘oh yeah, my mind also kept thinking that renewable energy is expensive’. No, it just seems to be expensive. I agree with the views of this article. And I’m at the side of renewable energy.

  • I am agree with above person. Renewable is not costly. But rest of article is good. Thanks for sharing.

    renewable energy sources capital cost is very high but running cost is less sometime zero.but efficiency is very low compared to non renewable energy sources

  • Renewable energy is expected to jump to 25 percent of global gross power generation in 2018, a rise on 20 percent in 2011 and 19 percent in 2006.

  • The above article provide quite useful knowledge of renewable source of is best and most suitable replacement of coal ,nuclear and other non renewable source of energy..although the capital cost is high but running cost is low

    Ex hydro generation has least running cost and also it is also beneficial for environment health
