Renewables Will Be World's Main Power Source By 2040, Says BP (cnbc.com) 334

An anonymous reader quotes a report from CNBC: In a not-too-distant future, renewable energy becomes the world's biggest source of power generation. A quarter of the distances that humans travel by vehicle will be in electric cars. U.S. dominance in the oil market begins to wane, and OPEC's influence is resurgent, as crude demand finally peaks. That is the vision laid out by British oil and gas giant BP on Thursday in its latest Annual Energy Outlook. The closely followed report lays out a vision through 2040 for Earth's energy future, provided government policy, technology and consumer preferences evolve in line with recent trends. BP forecasts that the world's energy demand will grow by a third through 2040, driven by rising consumption in China, India and other parts of Asia. About 75 percent of that increase will come from the need to power industry and buildings. At the same time, energy demand will continue to grow in the transportation sector, but that growth will slow sharply as vehicles become more efficient and more consumers opt for electric cars. But despite the increase in supply, BP thinks two-thirds of the world's population will still live in places with relatively low energy consumption per head. The takeaway: The world will need to generate more energy. The report says natural gas consumption will grow by 50 percent over the next 20 years, increasing in virtually every corner of the globe. "Throughout most of that time, the world will continue to consume more oil year after year, until demand ultimately peaks around 108 million barrels per day in the 2030s," reports CNBC. "This year, OPEC expects global oil demand to reach 100 million bpd."

Meanwhile, coal consumption is forecasted to flatline, as China and developed countries quit the fossil fuel in favor of cleaner-burning and renewable energy sources. "However, BP sees India and other Asian nations burning more coal to meet surging power demand as the nations become more prosperous," reports CNBC.

      No, they won't.

      There is nothing as energy dense, convenient, safe, and inexpensive as hydrocarbons. Maybe we can replace those hydrocarbons with something not from petroleum. Maybe we will use fuels other than hydrocarbons, but that doesn't mean the end for the internal combustion engine. The ICE is just too well entrenched in the culture, economy, and infrastructure to be replaced so quickly.

      Part of this infrastructure is the existing stock of vehicles themselves. A common diesel powered truck, tractor, locomotive, ship, or whatever, have a lifespan of decades. Anything sold in the last decade up to today will have a better than 50/50 chance of still being in use in 20 years. Even if no one made spare parts the existing stock of vehicles becomes a supply of spare parts. Then there's things like 3D printing and good old fashioned cottage industry of small time machine shops. People will be burning ethanol, vegetable oil, lubricating grease, solvents, or whatever else they can mix up to keep the wheels turning if something interrupts the supply of petroleum.

      No, the ICE will not be obsolete in20 years. Not unless there's some great leap in technology. That leap is unlikely to come from batteries. Sure, maybe the commuter car can be replaced with electrics. That won't mean much for the other vehicles that move, on the road and off.

          The basics of chemical storage of energy means that no battery can ever be as energy dense as gasoline.

          (btw gasoline is not safe.)

          Nothing is truly safe, it's all relative. We might find something more energy dense but then it's less safe. We can certainly find materials that are safer but far less energy dense. Given that balance of energy density, convenience, safety, and cost there is not much that can compete with gasoline.

          Batteries are not safe either. They can electrocute, burn, even explode, if not handled with due care. K

            • The basics of having to carry both fuel and oxidizer in a battery while with gasoline the oxidizer is pulled from the air. If you have an "air breathing battery" then that's pushing the definition of a battery, that's more a fuel cell than a battery.

              I could go on but I'll just stop at the definition of a battery. At least for now.

            Molten-air batteries of iron, carbon and vanadium boride have impressive numbers

            https://phys.org/news/2013-09-... [phys.org]

            watt-hrs per kg are 1400, 8900 and 5300 while the per liter numbers are 10k, 19k and 27k
            Gasoline is 12,200 watt-hrs per kg and 9700 per liter. Gasoline's significant per-kg advantage is diminished by it being consumed during use. Of course there are many hurdles to overcome for molten-air batteries so they won't be commercially available any time soon.

        I'd guess that it's more like 10 or so years from the start of a tipping point. By then about 20% of the cars will be electric, at that point gas will start to get cheap (with the removal of 20% of the demand), but banks and investors will stop financing oil projects (which require lots of money just to keep going). In about 20 years gasoline would be very expensive and pull the rest of the car market into full electric.

        Hydrocarbons are only inexpensive if you discount the externalities. The actual damage to the environment inherent in burning hydrocarbons is quite expensive.

      Of course. There will be no wind and solar dominating without the oil industry. From those oil wells comes a lot of natural gas, and that natural gas will be needed as backup power for the unreliable wind and solar.

      The oil companies have nothing to fear from wind and solar. They get to "greenwash" their industry by providing the natural gas to keep those windmills spinning. Oh, people do know that those windmills need power to get up to speed to catch the wind, right? They can't get going on their own,

      Actually once renewables exceed about 20% of the mix the requirement for backup starts to fall. Geographic distribution and high levels of predictability, combined with a distributed nature that means a single failure only takes out tens of megawatts instead of a gigawatt or two all make renewables more reliable, not less.

      Battery tech is going to make peaking plants unprofitable in the next decade or two max. Gas and other types of peak coverage can't react fast enough to compete with batteries. Environmental considerations don't even come into it. Best of all it allows individual energy users to buy their own batteries and avoid those high peak rates completely. Industrial users will level out their consumption, domestic users will charge up when it's cheapest and their solar isn't providing enough during the day.

      Any plan based on the old economics of base load and peak demand is going to fail. The nature of the grid and energy consumption is changing.

    I've got bad news, coal and nuclear are inadequate power sources because of the carbon or radio-isotope externalities they produce. We can't continue to rely on them because they are a threat to our species due to carbon held heat or radio-isotopes ruining our genome. Coal threatens the planet, nuclear threatens our species DNA, all species DNA come to think of it.

    However we can gradually phase them out with a steady increase in Solar PV, Solar Thermal, Wind, Geothermal. The good thing about this is it means a massive jobs growth all around the world as we build a 21st century infrastructure based on all the lessons we learned from those two energy industries.

    In the US alone there is terawatts of wind power available even before looking to solar PV or solar thermal. Even better news is that solar thermal is the ideal technology for baseload power. We've got a great future with these technologies. Whilst the transition won't be painless the knowledge that we are looking after future generations whilst taking responsibility for the mess previous generations have left us will mean our existence at this point in time has had a positive effect on those who come after us.

  • coal use will flatline and not decrease, oil consumption will increase 50%? all by 2030!
    i thought the plan was to make sure the use of all those energy sources would have been decreased dramatically by then, or the earth is lost.

      But we do have a stable power grid pretty much everywhere. And it's rapidly getting to the point where you don't need a rental or second car as a backup to your EV. The 2020 EV models have enough range that I would probably need a rental only once a year. I'd say my Volvo has about 4 years of life left in it. You can bet I'll be getting a electric when it gives up the ghost.
