Problems with Solar Energy – Why Solar Hasn’t Taken Over the World (Yet)

problems-with-solar-energy

Why are we experiencing problems with solar energy?

If solar is so absolutely great, and we’re hurtling towards a climate catastrophe, why does it only power about 2% of the world? If it’s the panacea to our problems, why aren’t solar panels adorning rooftops the world over? What are the causes behind the problems with solar energy that we face?

To answer such questions, we at UnderstandSolar have dug into the facts and present the fruits of our labor below – an unfortunate tale of G20 hypocrisy, the Concorde fallacy (find out what this is later), and the sobering fact that we still need fossil fuels to power our planet (at least for now).

6 suggestions to help you select the best home wind turbine

Just like with solar, which ranges from huge solar farms to small-scale residential solar installations, you now also have the option of installing the best home wind turbine for your particular situation.

Wind energy has seen a huge popularity increase over the last 10 years, mostly pushed forward by utility-scale wind farms–the rows of giant white wind turbines you’ve seen driving through the desert or plains.

Case in point: in 2016, our total wind capacity in the US equaled 82,000 megawatts. Compare that to our capacity in 2000 of just 2,539 MW and you begin to comprehend how much the industry has grown!Continue reading

The Lighter Side of Life with a Solar Panel Cartoon

If a Picture is Worth a Thousand Words, What About a Solar Panel Cartoon?

Cartoons can be a great way to find the humor in something: news highlights, politics, or to educate (and usually, some combination of the three). A lot can be said with few words – about solar politics, finances, and safety. Take a look at a solar panel cartoon or three that we found below!

Why Have Solar Power Subsidies in the United States?

solar-power-subsidies

Does the US still need solar power subsidies when solar is so popular?

Without getting into too many of the nitty gritty details, energy subsidies exist in order to help get new or struggling technologies off the ground and able to compete on their own, and solar power subsidies are no exception. The reason new technologies need help is simple: money.

According to a recent study, energy subsidies have been around since at least 1789, when our country placed a tariff on the selling of any British coal entering America. Since that time, federal money has flowed to industries such as coal, natural gas, oil, nuclear, and renewable energy.

What are the Benefits of Solar Energy?

benefits-of-solar-energy

Taking a societal look at the benefits of solar energy.

As you can probably imagine, there are many benefits of solar energy. We’ve written about the benefits and drawbacks of solar before in our October 2016 Solar Energy Pros and Cons – Top 10, but in that article we mostly focused on issues important to homeowners going solar – solar panel efficiency, cost-effectiveness, and the high upfront cost of solar panels.

Today, let’s take a step back and look at the benefits of solar energy on a much wider scale. We’ll delve into how solar can benefit a nation or society’s economy while increasing energy independence and financial security.Continue reading

How Many Solar Panels does it take to Charge an Electric Car?

how-many-solar-panels-to-charge-an-electric-car

How many solar panels are needed to charge an electric car?

The residential solar industry has enjoyed a huge growth spurt over the last decade due to falling prices and new financing mechanisms. At the same time, electric car ownership has grown steadily, pushed forward by companies like Tesla and Nissan that are constantly researching and developing new ways to make electric vehicles cheaper and go further on a single charge.

Some electric car drivers are even installing solar on their home’s roof to charge their car. An electric car powered by clean, renewable energy? Yes, please! This idea though might leave you asking the obvious question “How many solar panels does it take to charge an electric car?”
