Wind power and solar power from new power plants in Europe is significantly cheaper than electricity from fossil fuel or nuclear power plants when you factor in health and environmental damage, according to a new report.

The ‘true’ cost of electricity can be a difficult thing to calculate because of all the subsidies, taxes, and duties that the power sources receive, and that’s not even factoring in the impact these power sources have on human health, ecosystems, and free environmental ‘services’ (or so called “externalities“–externalized costs of doing business that someone else pays for).

So in a recent study, researchers from Green Budget Germany (GBG) took a closer look at these hidden costs, in order to get a better idea of electricity’s true cost. Their new research calculated the health and environmental expenses related to various currently-available energy sources.

According to that research, the cheapest energy sources in the world currently are wind power and solar power. “One kilowatt hour (kWh) of electricity produced by wind power stations on the coast or in the countryside costs an average of 0.07 euro (about $0.09).”

“New solar energy plants in central and southern Europe produce electricity for an average of 0.14 euro per kWh. In Germany, the cost is about 0.18 euro when using rooftop solar panels, while in southern European solar parks it costs about 0.10 euro per kWh.”

The report makes the point that electricity that is produced from new coal plants is twice as expensive as wind power, and around the same cost as solar power. This combination of increasing energy costs and continued innovation in clean energy technology will, by 2020, make wind power and solar power the cheapest way to produce electricity by far, according to the GBG.

Using fossil fuels to generate electricity results in pollutants that lead to high economic costs — in particular, greenhouse gases like carbon dioxide, according to the GBG report. As another example, the particulate pollution from coal power plants has been proven to regularly lead to respiratory disease. When a child develops a respiratory disease from this choice of power source, then it incurs high medical costs that are subsequently paid for by the government or the child’s family, and that’s not even including an effect this disease has on quality of life.

“An extensive 2006 study by Nicholas Stern, the former chief economist of the World Bank, also estimated high costs from the consequences of using fossil fuels. By the end of the century, it said the bill would total over 5 trillion euros ($6.4 trillion).”

It is coal power plants that are the most destructive to the environment, based on the research done by Barbara Breitschopf from the Fraunhofer Institute. “Power plant operators currently pay only a small portion of these costs as part of the so-called CO2 certificate. European citizens are currently paying about 0.09 euros per kWh for health and environmental damages by generating electricity from coal.

While wind power is considered to have a very limited effect on the environment, the production of photovoltaic cells for solar power currently does have some negative effect on the environment. To produce solar modules, a large amount of electricity is needed, which leads to higher emissions — this results in an extra cost of 0.01 cent per kWh.

Nuclear energy costs, predictably, much more than other sources because of the truly massive costs of disasters like Fukushima and Chernobyl.

The report continues:

Calculating the cost of nuclear energy is more difficult. A newly constructed nuclear power plant raises the average cost to about 0.20 euros per kWh, according to the California Energy Commission. By contrast, old, written off plants in Germany produce electricity at a bargain rate of 0.02 or 0.03 euros per kWh.

However, other risks not covered by power plants operators affect the total cost of nuclear energy, such as the chance of a nuclear accident. It’s estimated that Fukushima and Chernobyl have cost many hundreds of billions of euros, and that society has paid most of the damages.

GBG’s Bettina Meyer has analyzed studies on these external costs in her recent report. She estimates that additional risks raise the cost of nuclear energy to between 0.11 and 0.34 euros per kWh. If these costs were added to electricity costs, a kWh of electricity generated by a new nuclear power plant would cost between 0.31 and 0.54 euros and, if produced by an old plant, between 0.13 and 0.36 euros.

    This parallels work I’ve seen from Pembina regarding the true costs of coal. Coal costs 3.2 cents per KW hour but damages double the costs for the illness costs of smog. Add in Climate impacts, that results to an additional 3.1 to 10 cents on top of the previous numbers!

    I am really disgusted at the way all these issues are being handled.
    Regardless of the initial cost differential between a fossil fuel or nuke plant, and wind.solar, the ongoing fuel cost a NEVR factored in,…..NEVER……..ya, sure, all have maintenance….the least of which is solar……but we, the public, are being deliberately misled.
    I know EXACTLY how much solar costs….I am a solar provider of large utility scale and commercial systems. I charge $3.35 per watt for residential when we are a little slow between jobs, $3.15 for large commercial (under a MW) and $3.00 for 1 MW and over. PERIOD.
    Regardless of what anyone tells you, that’s what solar goes for, or should be going for in America. If I can do it, so can any sufficiently funded and managed company…I buy panels and inverters from the same companies as they can. But, I cannot speak for their motivations otherwise, such as stupidity, opportunism, and/or just plain greed.
    But what I see, is contractors are charging so much, that I could actually sell them the completed job as a “back end” , and they could make a whopper of a profit and still come out lower than the average “mom & pop” shop @ $4.75 to $5.25+ per watt. I see jobs like a 10KW on a home being over $15,000 more than I charge……absolutely disgusting.

      Stan, most likely we will end up with a few very large solar installation companies doing most of the installations. Economy of scale works.

      Get your business well put together. Get all the basics very solid. Then expand (smartly).

      We could say “We knew Stan back when….”.

    WOW, Europe only pays $0.09 euros/kWh for the hidden health cost of coal. The Harvard study on health cost of coal in US were much higher.

      yeah, crazy low… but not as crazy as not having one at all. :D

  • Carol Overland

    Where’s the link to the report? I’d like to know what externalities were factored in, how they were weighted, etc., the specifics!

  • David Fuchs

    Truth be told. Your numbers are off. Solar will beat wind in short order due to cost and efficiency. When plug in panels you can buy at the local home super store become standard everything changes.

    It just requires UL listing and an outlet.

    • Ross

      Wind is going to remain important in Europe because of its latitude.

    • Bob_Wallace

      I really don’t see the price of solar beating wind any time soon. The EIA isn’t projecting solar to be cheaper than wind even 20 years out.

      The future grid is not likely to be dominated by a single input. Solar is great, but it’s available only limited hours per day so it requires storage to provide during the non-sunny hours.

      Wind, even if was a penny or two more expensive, is better distributed, requiring less storage.

      Wind, solar, tidal and wave combined on the grid make for the most efficient use of storage.
