Renewable Energy Policies Actually Work (arstechnica.com) 205

Renewable energy use and reduced energy use overall have helped carbon emissions remain flat or below average as the global economy continued to grow over the years. But, as new research has found, government policy also appears to play a large role. Slashdot reader AmiMoJo shares a report from Ars Technica: The researchers started by identifying countries that show a "peak and decline" pattern of carbon emissions since the 1990s. They came up with 18, all but one of them in Europe -- the exception is the United States. For comparison, they created two different control groups of 30 countries, neither of which has seen emissions decline. One group saw high GDP growth, while the second saw moderate economic growth; in the past, these would have been associated with corresponding changes in emissions. Within each country, the researchers looked into whether there were government energy policies that could influence the trajectory of emissions. They also examined four items that could drive changes in emissions: total energy use, share of energy provided by fossil fuels, the carbon intensity of the overall energy mix, and efficiency (as measured by energy losses during use). On average, emissions in the decline group dropped by 2.4 percent over the decade between 2005 and 2015.

Half of this drop came from lowering the percentage of fossil fuels used, with renewables making a large contribution; another 35 percent came from a drop in energy use. But the most significant factor varied from country to country. Austria, Finland, and Sweden saw a drop in the share of fossil fuels within their energy mix. In contrast, a drop in total energy use was the biggest factor for France, Ireland, the Netherlands, Spain, and the United Kingdom. The U.S. was an odd one out, with all four possible factors playing significant roles in causing emissions to drop. For the two control groups, however, there was a single dominant factor: total energy use counted for 75 and 80 percent of the change in the low- and high-economic growth groups, respectively. But there was considerably more variability in the low-economic growth group. All of the high-growth group saw increased energy use contribute 60 percent of the growth in emissions or more. In contrast, some of the low-growth group actually saw their energy use drop.
So why are some countries so successful at dropping their emissions? Part of it is likely to be economic growth, but the biggest reason may have to do with government policies. "By 2015, the countries in the group that saw declining emissions had an average of 35 policies that promoted renewable energy and another 23 that promoted energy efficiency," reports Ars Technica. "Both of those numbers are significantly higher than the averages for the control groups. And there's evidence that these policies are effective. The number of pro-efficiency policies correlated with the drop in energy use, while the number of renewable policies correlated with the drop in the share of fossil fuels."

      In the U.S. one of our two major political parties represents a minority of voters

      Assuming you are referring to the Republican party and the last presidential election:

      No, the Republican party represents a majority of Electoral College voters. These are the people who vote the president in. This is the vote that counts.

      The Republican party received less votes when counting the totally unofficial and not used for anything popular vote. The competition wasn't run on the popular vote.

      If the game were to get the most votes (with no EC in between) then you can be sure that both parties would have played the game very differently. For this reason you cannot project the popular vote count of the last election onto this hypothetical election and say Democrats would have won.

      The rules were laid out and the Democrats didn't play the game as well. It's time to move on from that. If you want to change the way votes are counted then a preferential voting system is far superior to a simple "majority rules" system.

      My country uses this: https://en.wikipedia.org/wiki/... [wikipedia.org]
      We have almost 100% voter turn out (compulsory voting). We don't have Gerrymandering. We have an independent electoral commission.
      These are mainly good things (I don't agree with compulsory voting, I do see it's benefits).

      • Having a procedure electoral college between voters and the president doesn't in any way invalidate what the GP said given that there electoral college hours based on the decision of the population.

        All you really did whole pretending to disagree with the GP was provide a nice expatiation of why they were right.

      • Assuming you are referring to the Republican party and the last presidential election:

        No, the Republican party represents a majority of Electoral College voters.

        That does not mean they do not represent a minority of voters. The Electoral College is the mechanism by which they can win while representing a minority of voters.

        Also, you forgot Congress exists. The Republicans in the Senate represent a minority of voters, yet hold the majority.

        Talking about the Electoral College (or Senate apportionment) does not change that. You are just talking about the mechanisms that enable minority rule.

      Oddly it is the so-called "red" states that are leading in renewable power generation. But I guess that doesn't fit your idiotic narrative. The question is what you YOU doing about it? Do you own a car? Use electricity?

      • Considering the differing geographic conditions of US states, your argument is easily proven flawed. Even just mere geography introduces viability differences for various power sources, before politics comes into it. So even if it is true that '"red" states that are leading in renewable power generation', it doesn't really mean anything when it comes to how politics changes the outcome because the baseline is uneven to begin with.

      California has 55 electoral votes, 7 of which are due to illegals(*). The US census counts people, not citizens, in an area to determine how many electoral votes a state gets.

      California gets a significant extra amount of influence in elections due to the electoral college - are you willing to give that up?

      Also, the EC is what keeps California and NY from ganging up on all the other states. In effect, it prevents the US from having a civil war, and breaking up into smaller national entities.

        If you eliminate the Electoral College, how does California and NY "gang up" on all the other states? They're both about 40% Republican, and those votes suddenly matter when you've eliminated the Electoral College.

        There's 38.1 million people in the NYC, LA and San Francisco metropolitan areas. The other parts of both states lean heavily Republican. There's 157.6 million registered voters in the US. Let's pretend that every single person

        • Clearly we need to go back to some sort of 3/5ths compromise, right?

          You mean the compromise that limited the power of the slave owning states in the House of Representatives by 3/5ths? The people that wanted slaves counted equally were slave owners.

          I am always curious what people would do who bring up the 3/5ths. What would you have done? Sided with slave owners and counted slaves equally? Or would you not ratify the constitution?

      Are you claiming that the other party does not dance to the money of donors? The how did Bill and Hillary become multi-millionares on government pensions and salaries? How did Bernie Sanders afford multiple houses on a government salary? Where did Maxine Waters get her millions from?

      Stop being a partisan hack. It is unbecoming.

    • Where do you get this "Minority" datapoint from? Is that from Hillary Clinton winning the popular vote? Because if it is, your data is suspect. For one thing, almost all states are "Winner Take All" states. If the state is extremely Democrat leaning, most Republicans or even Independents will not even vote due to their vote meaning absolutely nothing. If you want to find out who is the actual minority, you would need to run a new election without the existence of the electoral college. In other words, you c

      The popular vote is a poor measure of whether one of the other party has a majority of the electorate. It does measure how many votes were actually cast, but keep in mind that both California and New York were conceded to the Democrats before the campaign started. Trump wasted very little time or money in either state.

      If the popular vote mattered, the end result would have been the same. How do we know that? Look at how the vote went for the House of Representatives - Republicans won. Or what if all states

    So why are some countries so successful at dropping their emissions?

    Because they export their polluting industries to the 3rd world like the US did to Mexico? This is an excellent example of an intentionally misleading analysis. CO2 emissions in CA and Germany have increased from 2010 till today. This is the period when we actually had a renewable energy policy, and the increase in CO2 was mostly due to bad renewable energy policy and doesn't count the extra emissions from methane we had during that same period.

    • Hmmm... US emissions are down, so we must be exporting it to Mexico? I guess that's why Mexico's emissions are also trending down [knoema.com]. Couldn't be we've let that "evil invisible hand" of capitalism work, could it?
      • Couldn't be we've let that "evil invisible hand" of capitalism work, could it?

        The Obama administration did quite a bit to promote renewables, higher emission/efficiency standards for vehicles, and limit CO2 production overall. Sometimes the invisible hand isn't that invisible. With that said, it's true that the market often only needs a gentle nudge in the right direction and can then take over.

    • by AmiMoJo ( 196126 )

      The EU successfully prevented the export of CO2 emissions by simply including emissions in the country of manufacture when calculating carbon taxes on EU companies. It also passed laws like RoHS that forced Chinese factories to clean up even though they were out of jurisdiction.

      Emissions since 2010 is a carefully cherry picked timeframe. Emissions are still falling, there was just a blip which was at its lowest point in 2010 due to the global financial crisis that is now being corrected.

    It's just a shell game. The fundamental trend over the time period in question has been to move all industrial production to China. Global CO2 increased because industrial activity increased. But the LOCATION of the production shifted to China. So if the laws are working, all they are doing is helping speed the catastrophic decline of the West's industrial base, and boosting China's GDP.

    The proponents of "green" energy always point to the early wins. There are a lot of easy wins early on in the process, when most energy still comes from nuclear, coal, or whatever. Those existing plants can adjust their output to allow for the massive fluctuations of solar and wind generation, as long as the solar/wind is a minor part of the grid.

    Things change when solar/wind become a large part of the generation capacity. On sunny summer days, Germany doesn't know what to do with all it's solar energy, and they've been know to pay other countries to take it. In bad weather, they import energy. Renewable energy on the massive scale Germany has implemented It only works, because they can leech off the capabilities of the countries around them. Germany's energy looks cleaner, because someone else is burning extra coal. If Germany is really does close their nuclear plants, the situation will get massively worse.

    Unless large scale energy storage is solved, renewable energy will remain limited in its potential. In addition, we will always need something to handle baseline load, for which nuclear remains the greenest and safest option.

    • The proponents of "green" energy always point to the early wins

      Considering the price developments, that seems rather nonsensical. Why point out the early things that were accomplished at very high price? Why not point out the recent installations with vastly lower costs? Nobody sane would do the former.

    • Germany's energy looks cleaner, because someone else is burning extra coal.

      Why "extra" coal? [energytransition.org] There's actually 20% less of it being burned.
