    • This pretty much sums it up... we are not doing enough, fast enough, to get global warming under control.

      Wind turbines, solar panels and electric vehicles are spreading far more quickly around the world than many experts had predicted. But this rapid growth in clean energy isn’t yet fast enough to slash humanity’s greenhouse gas emissions and get global warming under control.

      That’s the conclusion of the International Energy Agency, which on Tuesday published its annual World Energy Outlook, an 810-page report that forecasts global energy trends to 2040. Since last year, the agency has significantly increased its future projections for offshore wind farms, solar installations and battery-powered cars, both because these technologies keep getting cheaper and because countries like India keep ramping up their clean-energy targets.

      But the report also issues a stark warning on climate change, estimating that the energy policies countries currently have on their books could cause global greenhouse gas emissions to continue rising for the next 20 years. One reason: The world’s appetite for energy keeps surging, and the rise of renewables so far hasn’t been fast enough to satisfy all that extra demand. The result: fossil fuels use, particularly natural gas, keeps growing to supply the rest.

      “Without new policies in place, the world will miss its climate goals by a very large margin,” said Fatih Birol, the agency’s executive director.

      Here are the 5 trends:

      Renewable electricity is set to surpass coal. Soon.

      Coal has to be one of the worse possible sources of fuel. An environmental disaster.

      Offshore wind goes big. And mainstream.

      Encouraging that costs are falling.

      But....

      S.U.V.s are erasing progress from electric cars

      Can auto makers figure out how to create and sell battery powered versions?

      Energy efficiency efforts are slowing.

      I don't understand how Trump can even think about light bulbs.... really....he has nothing better to do with his time than roll back the standards for light bulbs? So trivial for the president of the United States to be involved in that. How much money did light bulb manufacturers pay to make that even a possibility? Must have been a lot.

      We replaced our light bulbs with LEDs and it has saved us a lot of electricity for such a simple fix.

      And why aren't building codes changing to make new ones more efficient?

      What happens in Africa is crucial

      I have to admit that I have never even considered Africa when I think about global warming. The potential for solar there is encouraging if it can be implemented. Huge upside there would be the boon solar electricity would bring to the people living there.

    • Yes, it going to get a lot worse before it starts to get better. The thing that gives me hope is the fact that going green is making economic sense, it's simply cheaper.

      This is a striking graphic:

      Vertical line is actual global solar capacity. Horizontal lines are the history of projections of growth. It has been constantly and significantly under-projected. On the other hand, coal has been consistently over-projected.

      Of course, it doesn't mean we're ok and there's no need to worry. We're not ok, and we need to worry, if not panic. But, projections about the future are probably off.
