What Are the Pros and Cons of Renewable Energy?
Will Nuclear Fission Save the World?
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 in detail the difference between nuclear fusion and fission, and why fusion has the potential to solve all the world's energy needs. In today's episode, Trace talks about which countries are producing the cleanest energy.
We've been seeing a big shift in investment and execution of renewable energy globally over the last decade. However, according to Bloomberg New Energy Finance's latest energy investment report, the U.S. is not really doing too well when compared with other industrialized nations.
Surprisingly, it's China who's leading as the world's largest investor in renewables. The U.S. boosted its investment 8 percent to $51.8 billion to move into second place, while Japan has become the second biggest market for solar power, up 12 percent to $41.3 billion. According to the Bloomberg Europe's investment grew one percent to $66 billion (U.S.) despite aggressive funding for offshore wind harnessing. Europe only grew one percent because they were already ahead of the game.
According to EcoWatch.com, five significant records were broken in 2014 vis-à-vis renewable energy. In Denmark, they set a record for wind production, with 39 percent of its electricity coming from wind. They're on track to get to 50 percent all renewable energy by 2020 and to be a 100 percent renewable country by 2050. In the U.K., wind power generation rose 15 percent, the largest rise by any country in any one year period. Renewable energy was the biggest contributor to Germany's electricity supply in 2014, with nearly 26 percent of the country's power coming from clean, renewable sources like wind.
What were the other renewable energy records in 2014, and why does the U.S. seem to be lagging so far behind? Trace tries to shed some light on this frustrating problem in this episode of TestTube Plus.

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."
