What is nuclear energy, and is it renewable?

Renewable energy may be the buzzword of the decade, but how do we classify an energy source as actually being renewable? And is nuclear energy renewable according to this official classification? In this article, we’ll break down the elements that allow us to use the ‘R’ word, and whether we should apply it to a widely used energy source like nuclear energy.

What Are the Real Global Warming Facts?

global-warming-facts

What’s really going on with global warming?

Although some believe that global warming is still an opinion that is up for debate, in actuality we’ve accumulated real proof for the phenomenon – based completely on research and evidence. Climate scientists have proven over and over that climate change is real, that human activity has negatively impacted our planet, and that things might get worse if we do not make some adjustments in how we do things.

Let’s go over scientifically proven global warming facts, including what it is, how we got here, and some ideas on what we can do about it.

Why is Renewable Energy Important?

why-is-renewable-energy-important

“How do I love renewable energy? Let me count the ways…”

Ever since school and poems by Emily Browning, we have been asking the question, “Why is renewable energy important?” What we all know by now is that renewable energy produces less emissions than traditional fuel sources like coal or natural gas, but did you know it can also strengthen your own energy independence, and build up your local economy?

Let’s take a look at each of these reasons to see why renewable energy is so important.

Solar Water Pumps: Versatile Wonders

solar-water-pump

Solar water pumps are cost-effective and have multiple uses.

Solar power is quickly becoming an affordable way to reduce energy costs. A novel way of saving money through solar power is the use of solar powered water pumps. Using a pump powered by the sun is a great way to provide water in places where conventional electricity is not an option, but what are they and why are they so great? Read on and we’ll explain!

The Duck Curve, or the Difficulty of 100% Renewable Energy Systems

renewable-energy-systems

Why’s it so hard to go to a 100% renewable energy system?

We often hear how renewable energy systems could easily power the world. Just throw up some solar and wind, add some hydro, and voila! we’re running on clean energy.

Unfortunately, though, it’s not that easy. Transferring to 100% renewable energy is fraught with difficulties, Today we’re going to focus on one huge issue with renewable energy: controllability.

Is the Tesla Off Grid Generator legitimate or a scam?

Nikola Tesla was a famous engineer and inventor best known for his contributions to electricity supply systems. Many have tried to imitate his greatness but few have succeeded. How can you tell if machines currently on the market that bear Tesla’s name, such as the Tesla “Off Grid Generator”, are fact or fiction?

Pros and Cons of Nuclear Energy

pros-and-cons-of-nuclear-energy

What are the pros and cons of nuclear energy, our third largest source of power?

Nuclear power plants produce 20% of all electricity used in the US, more than all renewable energy combined (including solar, wind and even hydropower), taking third place behind natural gas and coal (each of which accounts for about 30% of total electricity production).

With nuclear power covering a significant portion of our electricity needs, it obviously plays an important role in our society. On the other hand, we’ve also heard the horror stories about accidents at nuclear plants: meltdowns, leaks, evacuations, and even deaths.

In the US, these stories have tainted our view of nuclear energy (or maybe more accurately, given us a more rounded, accurate view). Case in point: the US is the biggest producer of nuclear power in the world, with 100 nuclear reactors across the country. However, we’ve constructed just a handful of new plants in the last 30 years (remember Three Mile Island’s 1979 accident?).

We use nuclear energy every day to meet our basic needs, but we’re all vaguely scared of it, having heard the terrible stories of what can happen when something goes wrong. So what’s the real story? Continue reading

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).

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!
