False enemies: emission reductions, renewables, and efficiency

Energy Transition

The EU’s new targets for 2030 are only for emissions trading. Anything adopted for renewables will not be binding, and we have yet to hear about efficiency at all. Craig Morris says we’re not going to get anywhere until we focus on all three.

Nuclear Power in the UK

The UK has successfully reduced carbon emissions from the power sector over the past two decades more than any other EU country except Germany. But instead of spearheading future progress, the two countries bicker over details – because their previous success came along much different paths. (Photo by Matthew StrmiskaCC BY-NC-SA 2.0)

 


The debate over 2030 targets is generally described as one between the UK, which plans to promote nuclear and shale gas, and Germany, which promotes renewables. I didn’t make up the confrontation between the two countries – here is British Energy Secretary Edward Davey himself tweeting that “I won for UK.” So who lost?

Secretary Davey should not be misunderstood as an opponent of renewables. He’s not the person who called renewables “green crap” – that was apparently Prime Minister Cameron, Davey’s boss. Davey recently told the Guardian that, “Renewables in any context, any scenario, are going to boom in the 2020s.” In his official statement, he says the new CO2 target will also lead to “many more renewables” (sic). Logically, renewables then do not need further support.

There is, of course, one thing that will stop renewables from booming: existing capacity. In its REmap 2030 roadmap (PDF), the International Renewable Energy Agency (IRENA) identifies “early retirement” of conventional capacity as one way of facilitating the further penetration of renewables (disclaimer: I served as the technical editor of that publication). Simply put, you’re not going to build wind turbines, solar panels, and biomass units if you’ve already got enough nuclear and natural gas turbines, for instance.

The UK does not, however. It is currently a major importer of electricity from the continent. The British need to build generation capacity but are not building renewables. The UK has a target of 15 percent renewable energy by 2020, though it is currently at less than five percent. The country plans to build nuclear and develop shale gas, and the British press sees the focus on carbon emissions for 2030 as facilitating those goals, not renewables. If enough nuclear plants and gas turbines are in the pipeline, the UK is not going to overbuild just to have renewables, too.

If we now adopt only carbon targets, how do we aim to meet them? A 40 percent reduction will eventually require a focus on heat and transportation, not just electricity, limiting the usefulness of nuclear. Lower emissions are easier when we reduce energy consumption, so why no efficiency target?

The discussion is being played out as though these goals were different options. In fact, they are tools in the same toolbox. Efficiency lowers consumption, renewables provide low-carbon energy (at a much lower price than new nuclear, incidentally), and emissions trading ensures that carbon is reduced within the gradually shrinking share of conventional energy.

But we’re not to do that. Could somebody please explain the logic of what we are to do? Some politicians say that we need to ensure that the transition to a low-carbon economy remains affordable and doesn’t hurt our economy. They then focus on carbon targets to protect us from the high cost of renewables, which are apparently harming a country with 5.2 percent unemployment in November(Germany), compared to 7.4 percent in the UK at the time. The British government is also willing to pay much more for new nuclear as onshore wind costs and new solar costs in Germany, allegedly in the name of protecting consumers from unnecessarily high costs.

The facts don’t matter, as the resistance to efficiency targets shows – what good reason do we have to oppose them? In the end, this is not just about the climate, not just about carbon emissions. It’s also about personalities “winning.” Over at the Carbon Brief, my colleague Mat Hope describes how top EU officials are willing to throw out all other targets so that binding carbon targets for 2030 can be a part of their legacy. So Davey, Barroso, and Hedegaard, congratulations: you win. Guess who loses? No, not Germany. Renewables and efficiency.

    I think efficiency is the right target. The market interest in renewables is there already and only growing. As renewables get built they are essentially obligate generators, they produce what they produce and existing generators produce the rest. As the supported efficiency measures begin to kick in and actual demand begins to fall the fossil generators are left picking up a smaller and smaller residual demand. Distributed renewables are particularly interesting because to the grid they simply appear as falling demand. The grid can not tell the difference between a 5 kw solar array coming out from behind a cloud to a 3-5 kw refrigerator compressor cycling off, they both appear like a 3-5kW drop in demand.

    Efficiency should be number 1 on the to do list. It is an easy, relatively fast and mostly cheap way to achieve meaningful reduction targets. As much as I love PV, efficiency technologies and improvements should be looked at in the home before you even start considering obtaining solar quotes, it is important to note that in the efficiency context, ‘behavioural efficiency’ should be part of the improved changes, e.g. Learn and get in the habit of turning the tv and lights off when no one is in the room, refrain from using the hot water tap from short and frequent burst and turn the STAND-BY power off

      Alen do both. Start the home efficiency while you are waiting for your PV quote.
      For me, it was only when I had PV on the roof and I had a ‘smart’ meter and and a In House Display unit that I could see how and when I was using electrons. I was able to better appreciate what and when I turned something on. And of course, look to how you heat your hot water.
