UN panel foresees 80 per cent of world’s energy as renewable by 2050

Solar and wind power could help fight global warming, panel says


 

The United Nations Intergovernmental Panel on Climate Change says that renewable resources (like solar and wind power) could provide up to 80 per cent of the world’s energy needs by 2050, helping to reduce greenhouse gases. In order to get there, governments will need to spend a lot more money and shift their energy policies to integrate renewable sources into existing power grids, the panel says. Further development of renewable sources will demand investments of $1.5 trillion by 2020, and maybe up to $7.2 trillion from 2020 to 2030, they said. The use of renewables is rising just as their price keeps declining, so the right policies could expand them significantly.

  1. ” …. could provide up to 80 per cent of the world’s energy needs by 2050 … renewable sources will demand investments of $1.5 trillion by 2020, and maybe up to $7.2 trillion from 2020 to 2030 … ”

    Not going to happen. Global warming is not occurring so there is no demand for trillion $$$ projects to fight something that is not happening. Secondly, George Monbiot had column in Guardian other day about incoherence of environmentalists and why few people are buying their message anymore.

    “You think you’re discussing technologies, you quickly discover that you’re discussing belief systems. The battle among environmentalists over how or whether our future energy is supplied is a cipher for something much bigger: who we are, who we want to be, how we want society to evolve. Beside these concerns, technical matters – parts per million, costs per megawatt hour, cancers per sievert – carry little weight. We choose our technology – or absence of technology – according to a set of deep beliefs; beliefs which in some cases remain unexamined.” George Monbiot, Guardian, May 3 2011

    • Much of this investment occur despite the ignoring of climate change. As the cost of renewables fall, they they will begin to displace fossil fuel energy sources.

    • Just a vast, global conspiracy of scientists then?

      Looks like I need a few more shares of Alcan

  2. Is this report supposed to make us feel like there is light at the end of the tunnel? To encourage us to pour money down the drain, because we know that ‘we can make it’. @Tony_Adams:disqus is right – unless you can prove GW (not climate change) then this is all moot. Let the market ‘reshape’ society, not social engineers with big hearts and small brains.

    • Exactly. I’m all for alternatives, but let them compete in the open market, on their own merit, without my tax dollars subsidizing a failed idea.

      • Under that logic, we never would have built a national highway or rail system. Hell, we wouldn’t even have telephone service in most of rural Canada.

        Some things we need to do publicly because the benefits, though large, are too diffuse for a private corporation to be able to do profitably.

  3. $8.7 trillion over the next twenty years might sound like a lot, but put it in perspective. Global GDP is currently $60 trillion per year. If global GDP rises by 3.5% per annum over the period, it will end up at about $120 trillion. Say the average over that time is $90 trillion–then that 8.7 trillion is only 0.5% of global economic activity over the next 20 years,

  4. I’d like to see more of a move to put Solar Panels on every roof, thus lowering everyones electricity bills instead of Mega Projects where corporations will rake in billions of dollar$ in profits..
