TEDx Talks
Environmentalists have long promoted renewable energy sources like solar panels and wind farms to save the climate. But what about when those technologies destroy the environment? In this provocative talk, Time Magazine “Hero of the Environment” and energy expert, Michael Shellenberger explains why solar and wind farms require so much land for mining and energy production, and an alternative path to saving both the climate and the natural environment. Michael Shellenberger is a Time Magazine Hero of the Environment and President of Environmental Progress, a research and policy organization. A lifelong environmentalist, Michael changed his mind about nuclear energy and has helped save enough nuclear reactors to prevent an increase in carbon emissions equivalent to adding more than 10 million cars to the road. He lives in Berkeley, California. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

Nuclear is the solution but more research should be done to improve long term waste management and failure prevention.

News flash: Nuclear power is the exact same thing that makes the Earth a molten rock 8000 miles across (with a few miles of cool crust). Simply live and work underground, or use geothermal. Free energy, folks. Iceland does it. Ironic, eh?

Solar panels degrade 1/2 of 1 percent per year. They should last 200 years, not 25. And in California they would pay off in about a year if you installed them yourself. So, they should be about 100 times cheaper than the grid. Arizona, New Mexico, West Texas, Hawaii etc have similar payoffs. And they would protect your roof, thus making shingles last longer, saving money. And why can't they be recycled when done? They would weigh MUCH, MUCH less than your car, and you throw that away in ten or fifteen years. TED isn't being completely honest here.

Am I the only one who saw the dude at 2:11 falling asleep? xD

He never exactly answered what we end up doing with the waste, he only said that was “safer”. What if “safer” means we just dump the nuclear waste into our environment away from any cities, cause we can’t exactly just make nuclear waste disappear.

the solution is to put windmills and solar panels on peoples homes. Not to make farms of them, like everybody is doing. Your argument is flawed, only considering farms of renewable s, thats it. So you dont know.
100,000 year nuclear waste is not an option.

The real answer to the problem is a paradox. If you want to make the world a better place for your kids, don't have kids.

Solar panels doenst die after 25 years - they reach 80% of original output after 25 years. You can easily keep solar panels for 50 or even 75 years and still have reasonable output. So another misleading comment from this guy.

Nuclear power isnt clean and not contributing to planet heating. It is heating entire rivers and changing ocean temperature within many miles. The extraction of uranium isnt clean and CO2 neutral. The maintenance and building of nuke plants isnt CO2 neutral. Chernobyl and Fukushima certainly let out a lot of air pollution that isnt going to disappear for a long time.

Let's talk back in 25-30 years. I don't believe people will invest in expensive electricity from nuclear. Renewables + storage will be cheaper than everything else, and certainly cheaper than nuclear.

Fission now, fusion when we can.
blakespower
problem with nuclear is they store all the waste on site, at least in the usa.
Rhysand
N2N is the solution. Natural Gas now (puts out half the pollution of coal and oil, and estimated reserves could power the world for 200 years or more) until we can make nuclear fusion a reality, and then fusion. Plus this allows us to save oil and petrochemicals for the manufacturing of materials in our everyday lives, which is absolutely essential to our lives. Imagine a world without plastic, or clothes, or shoes, or computers, or phones, or batteries, or literally everything we have. All of these materials are petroleum products. They can be made without petroleum, if one desires to pay ten times more for them, which literally no one can afford unless you are a rich liberal in hollywood.
Lazar Cvijovic
Everything makes sense. But how come it is a concern if waste from solar cells is properly disposed and disposal of depleted uranium isn't? Much of depleted uranium isn't disposed properly, far from it.
Mark Gilbert
WOW! The alternative view was actually allowed to be presented?!?! ...There's still hope for a balanced discussion on climate change and environmentalism!!!

Reduce the world population to 2 billion via education and encouragement. This will have the greatest effect on climate change.
Donald Sexton
Many valid points although the water resource issues involve altering watersheds, excessive extraction, & exploitation without infiltration along with sedimentation within the reservoirs that reduces volume are among the deleterious effects upon the hydrologic cycle. The supposed "climate change" description is terribly simplistic, misleading, & derivative when there are many contributing issues but exploited with misinforming propaganda & conniving or dangerous interests rife with greenwashing & harmful actions without guaranteeing resolution & often obfuscation. Appreciate your consideration.

This talk was given at a local TEDx event, produced independently of the TED Conferences. As an industry insider, Alan Lewis knows just how badly the food system is broken. In this high energy TEDx talk, Alan reveals the sophisticated methods used by the food industry “fibberati” to manipulate, deceive and distract us. If you have ever read a food label and felt you were being lied to, you have felt the “dark mark” of the fibberati. We can resist these nefarious tactics by making conscious food choices based on core values that support a sustainable and just food system.

Alan directs Government Affairs and Food and Agriculture Policy for Natural Grocers by Vitamin Cottage, a 60-year-old health food chain operating over 85 stores in fifteen states. He is active in many trade organizations and sits on the Boulder County Food and Agriculture Policy Council. His focus is on communicating with local and federal policy makers using frameworks that are non-confrontational and inclusive -- except for tonight. He has lived for extended periods in Portugal, Haiti, and Dominica, where he developed a keen appreciation for the variables of agriculture production and food systems within different geographic, cultural and economic contexts.

About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
