Renewable Energy Production Surpasses Nuclear In the US

During the first three months of 2011, energy produced from renewable energy sources (biomass/biofuels, geothermal, solar, hydro, wind) generated 2.245 quadrillion Btus of energy equating to 11.73 percent of U.S. energy production.

      Yeah I keep hearing these same quotes that either ethanol uses more energy to produce or it breaks even. I rarely hear anyone sourcing where this information comes from or a breakdown of these energy costs. Most of the petroleum costs that are quoted refer to fertilizer and tractor fuel, etc and not the actual production of Ethanol. I believe they generally use natural gas in the production.

      Most of it sources papers by David Pimentel who seems to have a real axe to grind against ethanol. There are a lot of contradictory studies too.

      From an energy standpoint, the problem with ethanol from food crops is that we've reduced the labor to produce food crops by massively increasing the energy costs. That is, as technology drives the cost of energy down and the standard of living up, labor becomes much more expensive than fuel. So food production has been optimized to minimize labor, substituting the burning of more energy instead. Think about it - you can't eat oil. But by mechanized growing of crops, you can turn oil into food. Since food is much more important than oil, it makes economic sense to pump more energy into food's production than you'd get back if you merely burned the food as fuel.

      The U.S. produces an excess amount of food (particularly corn) in order to stave off famine should there be another major crop failure like in the early 1930s (this is the primary rationale for farm subsidies). Consequently, we're left wondering what to do with all this excess corn. Some gets donated as foreign aid. Some is converted into high fructose corn syrup. Some is used as cattle feed to lower the price of steaks, since people like steaks. And we still have tons of it left. Someone came up with the bright idea of turning it into ethanol to help reduce our dependence on foreign oil. If you add up all the energy used to produce corn ethanol, I'm fairly certain it would cost nearly as much or more energy than the fuel it produces. But that's beside the point because that corn would still be produced regardless of whether or not it's converted into ethanol.

      The real problem with turning food crops into ethanol is that there's no market barrier between the two uses. If the price of fuel goes up, more corn gets shifted into ethanol production, meaning less corn for food, meaning food prices go up. If we're going to be turning corn into ethanol, then the farmers (farming corporations really) should be required to specify at planting whether that field's crop is going to be used for food or for fuel. That way the government can still work to ensure there's still an oversupply of food, and farmers aren't tempted to sell their food corn as fuel corn should the price of gas rise.

    No one will let nuclear power scale. We haven't actually built a new nuclear plant in 30 years. With old ones simply wearing out means nuclear is on a decline that just can't be stopped without new plants.

    That said, most of the US energy supply still comes from coal and gas (in that order), with 'renewables' as a group taking a distant third, and nuclear still chugging along in a close fourth. We don't seem to really be decreasing coal and gas use, which are real problem areas and instead focus on the perfectly adequate nuclear as what needs to go away.

    I'd really rather they replace some of those craptastic coal and gas power plants that make up the bulk of our energy production.

    The reason that talk about BTUs is that they are talking about all types of energy consumption even the burning of wood in home stoves. Wood is renewable but produces carbon dioxide and sulphur dioxide. Just because it is renewable does not make it green. Take a look at this http://www.eia.gov/totalenergy/data/monthly/pdf/sec7_5.pdf

  31. Stopgap Measure by Anonymous Coward · · Score: 2, Interesting

    I think one of the major things that a lot of people are missing is that nuclear energy should be seen as a stopgap measure. We don't know if the climate can continue to support coal and oil based power sources. It might, but then again it might not and I don't think thats a risk people are willing to take.

    The major problem with current wind, solar, and basically any other power source dependent on the sun is that its only on-line for half the day. The other half has to be taken up by coal and oil plants. It's not easy to spin up or down a generator on the fly so most of the time they just leave them running even if no one is burning the power. Compounded by the unpredictability of solar power (wind, wave, and various light based technologies) "backup generators" have to be left running for the event that there is a break in the supply (cloud) or spike in demand. That said, I would like to see numbers stating how much oil / coal is burned to backup the "green" tech. This is also why net metering is such a problem for both the gird and the environment. Not to mention the truly horrible chemicals used in PV fabrication or any other IC for that matter.

    It's my hope that in twenty years we will have better solar panels and battery technology. There are research groups making great strides in both directions. However, without higher efficiencies in both categories these alternative power sources remain largely nonviable. Further, impact of manufacturing and disposal needs to be considered. That is not to say we shouldn't invest but we need clean sources to get us from here to there.

    Personally I'm sticking with high MPG pure gas cars and nuclear power for now and hoping for a brighter future.

    I really have to wonder if it's even practical to move to an all renewable energy source infrastructure?

    Wind and solar take a LOT of space. As it is, bird people, environmentalists and "I don't want to see it but I want the benefits from it" people don't want wind and solar stuff all over the landscape. Geothermal energy is one usually of opportunity and while technically it's everywhere, tectonically, it's not quite as available everywhere. And hydro electric? Do we have enough rivers?

    And here's a thing -- even if we shut everything down now, we're already past the point of no return where global warming is concerned. We are going to see a continuation of a change in global weather patterns which mean rain, wind and water will all continue to change movement patterns which will transform where farming is done and more. What is a good location today, will not likely be a good location tomorrow and we don't really know yet where the good locations of tomorrow will be.

    We don't need figures saying what we can and are doing today, we need to know if it's even possible to do what we wish for. Can we get 100% clean? If so, how can we do it? Is it sustainable? I'd really like to know.
