Topic: Energy

Directed by Lisa LaBracio All around the world, millions of people are flipping a switch, plugging in, and pressing an ‘on’ button every second. So how much electricity does humanity use? And how much will we need in the future? Discover how much energy it takes to power the world, and how clean energy sources could help revolutionize our electricity supply.

Video produced by Reimagine Films (www.reimaginefilms.com.au) Energy is the lifeblood of our modern life. It powers our industry, it fuels our cars, and charges our iPhones. A solution is a transition to clean energy sources. The brilliant thing is that we have huge amounts of free, renewable and clean supplies of natural energies like wind, sun and oceans.

Imagine aliens land on Earth a million years from now. What will these curious searchers find of us? They will find what geologists, scientists, and other experts are increasingly calling the Anthropocene, or new age of mankind. David Biello explains how the impacts that humans have made have become so pervasive, profound, and permanent that some geologists believe we merit our own epoch.

Every year, the world uses 35 billion barrels of oil. This massive scale of fossil fuel dependence pollutes the earth, and it won’t last forever. On the other hand, we have abundant sun, water and wind, which are all renewable energy sources. So why don’t we exchange our fossil fuel dependence for an existence based only on renewables? Federico Rosei and Renzo Rosei describe the challenges.

How do we build a society without fossil fuels? Using her native Costa Rica as an example of positive action on environmental protection and renewables, climate advocate Monica Araya outlines a bold vision for a world committed to clean energy in all sectors.

Solar power is cheaper and more sustainable than our current coal-fueled power plants, so why haven't we made the switch? The real culprits here are the clouds, which make solar power difficult to control. Alexandros George Charalambides explains how solar towers and panels create electricity and how scientists are trying to create a system that can function even under cloud cover.

Many of the inanimate objects around you probably seem perfectly still. But look deep into the atomic structure of any of them, and you’ll see a world in constant flux — with stretching, contracting, springing, jittering, drifting atoms everywhere. Ran Tivony describes how and why molecular movement occurs and investigates if it might ever stop.

Hank, from the youtube channel SciShow, explains the power of solar energy and describes how it may fit into our diversified energy future.

The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy.

When he was just 14 years old, Malawian inventor William Kamkwamba built his family an electricity-generating windmill from spare parts, working from rough plans he found in a library book.

At TED2010, Bill Gates unveils his vision for the world's energy future, describing the need for "miracles" to avoid planetary catastrophe and explaining why he's backing a dramatically different type of nuclear reactor. The necessary goal? Zero carbon emissions globally by 2050.

How much land mass would renewables need to power a nation like the UK? An entire country's worth. In this pragmatic talk, David MacKay tours the basic mathematics that show worrying limitations on our sustainable energy options and explains why we should pursue them anyway.

Energy is neither created nor destroyed — and yet the global demand for it continues to increase. But where does energy come from, and where does it go? Joshua M. Sneideman examines the many ways in which energy cycles through our planet, from the sun to our food chain to electricity and beyond.

It takes a lot of fuel to heat our homes, preserve our food, and power our gadgets. And for 40 percent of the world, cheap, plentiful coal gets the job done. But coal also releases pollutants into the air, causing environmental damage like acid rain and serious health problems. Can we create a cleaner version of coal? Emma Bryce details the three ways we might strip coal of its foul forces.

Biofuels can provide energy without the reliance on environmentally harmful fossils fuels -- but scientists are still searching for a plentiful source. Craig A. Kohn demonstrates how cellulose, the naturally abundant tough walls of plant cells, might be the solution.

How do we know what matter is made of? The quest for the atom has been a long one, beginning 2,400 years ago with the work of a Greek philosopher and later continued by a Quaker and a few Nobel Prize-winning scientists. Theresa Doud details the history of atomic theory.

This video is an introduction to Rawlemon Solar Energy Generator. It shortly explain the principles of our patent pending micro tracking system, and few applications we are working on.

Ric Kaner set out to find a new way to make graphene, the thinnest and strongest material on earth. What he found was a new way to power the world.

We're already seeing the devastating effects of our changing climate on real peoples' lives. And we know that greenhouse pollution from fossil fuels is the main contributor to climate change.

Economist Nat Keohane uncovers the real facts behind clean energy legislation in our short video: "The Facts of Cap-and-Trade." With some help from a team of animators, Nat explains why a cap on global warming pollution is the best option to create a better future for America.

Our hundred year relationship with oil is at a crossroads. The Deepwater Horizon oil spill has shone a light on the far reaching consequences that our addiction to oil is having on the natural world and on the climate. Instead of chasing the last drops of dirty oil, we need to kick-start the clean energy age. We have one planet, and if we’re going to protect it, everyone - from local communities, to businesses and governments - will need to come together to go beyond oil.

The CSIS Energy and National Security Program and the Joint Institute for Strategic Energy Analysis hosted a discussion of the geopolitical implications of current clean energy trends. The session began with a presentation on the trends and state of the clean energy economy, looking at clean energy penetration, finance, and policy support across the globe. This was followed by a discussion on the traditional geopolitical and market challenges facing clean energy technologies, emerging characteristics of the clean energy economy, and challenges of moving forward.

It turns out that clean, sustainable energy simply makes good business sense, on a global scale. And there are trillions of dollars of profit to be made in the conversion from the 20th Century’s fossil-fuel based economy to the inevitable 21st Century renewable energy infrastructure.

Nearly two years after the TVA Kingston Coal Ash Spill, many have already forgotten its impacts on the community and the environment and yet the TVA coal ash spill is still the largest industrial spill in American history. It was six times larger in volume than the BP Oil Spill in the Gulf of Mexico.
