What Are the Pros and Cons of Renewable Energy?
Which Countries Are Producing the Most Clean Energy?
Each week on TestTubePlus, we pick one topic and cover it from multiple angles. This week's subject is alternative energy. To start things off, Trace explained the difference between renewable and nonrenewable energy sources. In the second and third episodes, he was joined by DNews co-host Julian Huguet to discuss the pros and cons of different renewable energy sources and they explained the difference between nuclear fusion and fission, and why fusion has the potential to solve all the world's energy needs. Yesterday, Trace surveyed which countries are producing the cleanest energy around the world. For today's final episode, he'll be discussing some fascinating and bizarre ways of producing energy.
By now, everyone should be well aware of the problems of burning fossil fuels for energy, and we've discussed a bunch of different clean, renewable energy sources like wind, solar, and nuclear fusion. But what about geothermal energy which captures heat given off by active volcanic areas around the world? By now we're familiar with wind turbines on the ground, but what about turbines propelled by blimps 1,000 feet in the air where wind currents are much stronger? What about satellites with solar panels that collect all that solar energy normally absorbed by our atmosphere? What about trying to harness the power of all the ocean's waves? Since the Earth is 70 percent water, scientists estimate that the energy contained contained in ocean waves is five-times the amount needed by global demands.
These are just a few of the fascinating and innovative, potentially new ways to harness clean energy from the Earth to power the Earth. Check out the videos for the rest of these crazy ways we may be generating power in the future. If we've forgotten any, or if you think you can come up with other ways, let us know in the comments below.
TestTube Plus is built for enthusiastic science fans seeking out comprehensive conversations on the geeky topics they love. Each week, host Trace Dominguez probes deep to unearth the details, latest developments, and opinions on big topics like stereotypes, fear, terrorism, alcohol, survival, black holes, dreams, space travel, and many more.

Technology: Why wave power? (Aquamarine Power)
"Ocean waves represent our planet's last untapped natural renewable energy resource. Over 70 percent of the earth's surface is covered with water. The energy contained within waves has the potential to produce up to 80,000TWh of electricity per year - sufficient to meet our global energy demand five times over."
Clean Energy Investment Jumps 16%, Shaking Off Oil's Drop (Bloomberg Business)
"New funds for wind, solar, biofuels and other low-carbon energy technologies gained 16 percent to $310 billion last year, according to Bloomberg New Energy Finance. It was the first growth since 2011, erasing the impact of lower solar-panel prices and falling subsides in the U.S. and Europe that hurt the industry in previous years."
5 Countries Leading the Way Toward 100% Renewable Energy (EcoWatch.com)
"2014 was an exciting year for renewable energy. After a three-year slump in renewable energy finance, investment grew last year, with records level seen for the amount spent on wind farms, as well the construction of both new wind and solar capacity."
The Radioactive Boy Scout (Harpers Magazine)
"The force hidden in the atom will be turned into light and heat and power for everyday uses. Chemists of the future, working with their brother-scientists, the physicists, will find new ways of harnessing and using the atoms of numerous elements-some of them unknown to the scientists of today."
How much of U.S. carbon dioxide emissions are associated with electricity generation?(U.S. Energy Information Administration)
"Total U.S. energy-related emissions of carbon dioxide (CO2) by the electric power sector1 in 2014 were 2,043 million metric tons, or about 38% of the total U.S. energy-related CO2 emissions of 5,404 million metric tons in 2014."
Fossil fuel (ScienceDaily)
"Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals. In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources. These are sometimes known instead as mineral fuels."
Nonrenewable and renewable energy sources (U.S. Energy Information Administration)
"Energy sources are classified as nonrenewable if they cannot be replenished in a short period of time. Renewable energy sources such as solar and wind can be replenished naturally in a short period of time."
