You've Never Heard of the World's Most Common Mineral
AdultsEducationScienceWork...The most common substance in the world is literally IN the world. It's a mineral called bridgmanite, and it belongs to a class of minerals (called perovskites) that scientists are trying to use in the next generation of solar panels.
Is Nuclear Power “Too Expensive”?
AdultsEconomyEducationTechnology...The best argument against nuclear power, maybe the only real argument, is that nuclear power is “too slow” to build and is “too expensive” to finance. Is this true?
Are solar panels worth it?
AdultsHealthHistoryTechnology...Today in many countries solar is the cheapest form of energy to produce. Millions of homes are equipped with rooftop solar, with most units paying for themselves in their first seven to 12 years and then generating further savings.
How Can We Store Renewable Energy?
AdultsConstructionScienceTechnology...Decarbonizing our power production is vitally important if we want to curtail climate change, but there are some major logistical issues we’re going to have to overcome before we can do that.
How do wind turbines work?
AdultsNatureScienceTechnology...Explore how wind turbines convert wind into electricity, and the challenges of powering the world entirely with wind energy.
How much land does it take to power the world?
AdultsIndustryTechnologyWorld...Explore the sustainability of fossil fuels, nuclear power, and renewable energy and how much space each of these power sources use.
How much electricity does it take to power the world?
AdultsEducationTechnologyWorld...Discover how much electricity humanity uses, and how clean energy sources could help revolutionize our energy supply in the future.
How Many People Did Nuclear Energy Kill? Nuclear Death Toll
AdultsEducationEnvironmentHistory...Nuclear energy creates an uneasy feeling of danger for many people: ancient and dangerous minerals are concentrated to awaken seemingly unnatural powers, creating toxic elements that, if they escape, can and have killed people in horrible ways. How many people has nuclear energy killed and how?
Building the world's largest (and most controversial) power plant - Alex Gendler
AdultsConstructionDesignIndustry...Explore the creation of China’s Three Gorges Dam, and find out how the hydroelectric plant generates its power.
Why Can't We Get Power From Waves?
AdultsNatureScienceTechnology...Wave power hasn’t yet made a splash because it’s hard to use waves to spin turbines, and because the sea is a harsh place to build things.
How does fracking work? - Mia Nacamulli
AdultsGlobal WarmingNatureTechnology...Deep underground lie stores of once-inaccessible natural gas. There's a technology, called hydraulic fracturing, or "fracking," that can extract this natural gas, potentially powering us for decades to come. So how does fracking work and why is it a source of such heated controversy? Mia Nacamulli explains the ins and outs of fracking.
Why there are twice as many solar jobs as coal jobs
AdultsGlobal WarmingTechnologyWork...America is changing how it gets its energy, and coal is losing out.
Storing the Sun's Energy in Liquid Could Change Solar Forever
AdultsGlobal WarmingTechnologyScience...Researchers have just found two new ways to make solar power more efficient. Could this solve our energy crisis?
What are the challenges of nuclear power? - M. V. Ramana and Sajan Saini
AdultsGlobal WarmingTechnologyEnergy...Our ability to mine great amounts of energy from uranium nuclei has led some to bill nuclear power as a plentiful, utopian source of electricity. But rather than dominate the global electricity market, nuclear power has declined from a high of 18% in 1996 to 11% today. What happened to the great promise of this technology? M.V. Ramana and Sajan Saini detail the challenges of nuclear power.
