Global Weirding with Katharine Hayhoe
Renewable energy is a nice fad and all, but it’s way too expensive. What about poor people?

Find out in this all new episode of Global Weirding.

Global Weirding is produced by KTTZ Texas Tech Public Media and distributed by PBS Digital Studios. New episodes every other Wednesday at 10 am central. Brought to you in part by: Bob and Linda Herscher, Freese and Nichols, Inc, and the Texas Tech Climate Science Center.

@0:47 when you say "coal, oil, and gas," i think "gas" is meant to refer to natural gas, methane, not gasoline (petrol in British I think) made from oil. Is the little red guy on the right a gasoline canister? I think the middle guy is oil. Is the guy on the left coal?

With applications of renewables, the gap between the rich and the poor, the old and the young may be tightened. My unofficial chemical teacher always tell me science must be accurate, no " may, likely, I think...". What a fuss!

I think one way to avoid bird killing by wind turbins' blades is to painting the blades with different color, for example, red. Is it ok?
Those outdoor cats... damn we need to get rid of them!

Please keep up your argument. One day, after you're battered and bruised, you will have progress.

I recommend Alex Epstein at Center for Industrial Progress.

It’s a nicely presented video, but low on facts and high on moralising.

I don’t trust your expertise on energy. Your background seems to be in climate science. I’d rather take advice on energy from someone who’s actually studied that field.

Katherine, it seems like you’re the one trying to tell Africa how it should develop.

“Indoor pollution from biomass cooking – a task usually carried out mainly by women – will soon kill more people than malaria and HIV/AIDS combined.” Not all “renewable” energy sources are good for humans.
The Impossible Conversation
This is a very clear and important message about our energy choices and the twisted corporate propaganda that tries to keep us on an ecocidal fossil fuel track. Thank you for the bold clarity of the message.

When you take away those nations and billionaires their way of getting trillions and billion of dollars. It's easier to make you disappear all together then to create much chaos to western and middle eastern countries.
So thanks, but I'm still relying on oil and coal. It's not a choice rather a forceful one. The one decision that makes me feel like a murderer of planet earth.

Industrial wind turbines come at a big aesthetic/wildlife cost that weak environmentalists choose to ignore. They also aren't very reliable and you need fossil fuels to build them! Germany has learned a lesson that others should heed:

Me ajudou muito a entender melhor sobre energias renováveis! Muito obrigado!

Thank you. Has anyone voiced the matter that the output per turbine is such that it takes billions of them to produce an amount of energy that is significant, e.g. 50% of USA national need? How can that output per turbine Exponentially increase to 10,000/ 100,000, 1 million, 1 billion Times where it is today along with storage increases?
Paul Adams
Brilliant video thanks

Switch the 6-50watt glass panels to 6-18 100watt flex panels and increase motor to 1000/1500watt.
Mobile Solar, low cost, highly versatile.
Design them to be job specific, put on a plow, seed dispenser and scraper, ideal garden/farm machine.
Mobile Solar will definitely lower the amount of energy humanity uses.

Bid farewell to high electric bill. You could make your own power with generating power method “boma fetching unique” (Google it), which means you are saved from paying high electric bills. With a few simple tricks and minor adjustments to the way you operate your home appliances, you could drive your energy costs down.
