IEA Says World’s Electricity Supply Needs To Be Flipped From Fossil Fuels To Renewables

Originally published on RenewEconomy. As Tony Abbott prepares to wipe out the remaining institutions supporting the deployment of renewable energy technologies in Australia, the International Energy Association has urged countries to act quickly in the opposite direction, and seek to reverse the respective share of fossil fuels and renewable energy sources by 2050.

Wrightspeed’s Series Hybrid Retrofit Kit For Garbage Trucks — Making Waste Cleanup Cleaner Than Ever

Good news for our waste haulers and urban environment — Wrightspeed’s new series hybrid powertrain retrofit sets a high standard anywhere waste needs picked up. Wrightspeed’s series hybrid retrofit waste haulers makes sense, saves money, and protects the environment. According to GM-Volt.com, waste haulers that use this retrofit can reportedly be cleaner (all things considered) than

Elon Musk On 100% Renewable Energy, Solar Energy Potential, Li-ion Battery Components…

Originally published on Lenz Blog. It is of course correct that eventually all energy will be renewable, and the only question is how fast that happens. Fossil fuel will run out eventually. It is also correct (in my opinion) that we should rather not gamble with the amount of CO2 that can be safely released.

Aircraft Engines That Use Less Fuel & Can Last Three Times As Long Via New Nanoparticle Coating

The service life of aircraft engines can be greatly increased, by up to 300%, through the use of a nanoparticle coating, according to new research from University West in Sweden. This nanoparticle coating also allows the temperature within the engine to be raised, which would increase fuel efficiency — resulting in decreased fuel use, and

Germany Fossil Fuel Production Drops, Electricity Exports Soar

Originally published on RenewEconomy. As Germany chancellor Angela Merkel said last month, if Germany can succeed with its ambitious energy transition then other countries could too. “If we succeed, then she (the Energiewende) – and I’m convinced of it – will become another German export hit,” she said. “The world looks with a mixture of a

Germany CO2 Emissions From Power Sector Unchanged


Originally published on Renewables International.
By Craig Morris

The AGEB published its official review of German energy in 2013 yesterday, confirming our estimate from January: CO2 emissions from power are down.

The official figures from Germany’s Environmental Agency (UBA) are not yet in, but AGEB has published its official estimate of energy statistics for 2013. For the power sector, the original preliminary report from December did not contain any estimate of carbon emissions, or of actual coal consumption (primary energy). Rather, it only discussed power production (final energy).

But as our Thomas Gerke pointed out in January, carbon emissions are related to the amount of primary fossil energy consumed, not the amount of final energy produced. Germany is making more electricity from less coal. Gerke estimated that carbon emissions from the power sector – remember, we are only talking about electricity, not total energy consumption – must be down by around 0.3 percent.

Now, the AGEB has confirmed his findings, though they refrained from stating outright that carbon emissions are down. Here is the statement from the press release (PDF, all texts only in German; these are my translations):

Lower emissions from natural gas turbines and lignite power plants compensated for the increase in CO2 emissions from hard coal plants.

A more literal translation would read that the “increase” in CO2 from hard coal was “balanced” by the drop in consumption of natural gas and lignite for power.

The full report (PDF) states that CO2 emissions “are practically unchanged year over year.”

While power from natural gas shrank considerably, the increase in electricity from lignite and hard coal was compensated for by greater use of renewables, so that the CO2 intensity of power generation remained the same in 2013 as in the previous year.

The figure given for 2013 for “general power supply” is 0.51 kg of CO2/kWh. Strangely, no number is reported for the previous year. If you want to compare, you have to go find the official report for 2012 (PDF). Et voilà, the figure for that year is 0.52 kg of CO2/kWh. Carbon emissions from the German power sector were down in 2013.

The Berlin-based think tank Agora Energiewende is only one of a large number of organizations that estimated higher carbon emissions from the German power sector based on an uptick in final energy (electricity) from fossil fuel. Agora has made quite a splash with its “Energiewende Paradox” (meaning that the Energiewende is leading to higher carbon emissions from the power sector), but the real paradox is that no one is reporting that carbon emissions from the power sector are down. Agora is itself working to reduce carbon emissions, so the think tank probably cannot use the news about lower carbon emissions.

Why is this message suppressed?

In any normal situation, such hard facts would simply be reported – it’s not like there’s no way to say “carbon emissions are slightly down year-over-year” in German. But the AGEB writes only that “Germany was probably not on target for its carbon emission reductions in 2013.” The organization is focusing on total energy consumption, not just power. In other words, Germans actually are seriously concerned about carbon emissions, and they are not going to celebrate some minor downturn in the smallest of the three main energy sectors (Germany consumes roughly a fifth of its energy as electricity, but 2/5 as motor fuel and 2/5 as heat).

Why is Renewables International celebrating this outcome? We’re not; we are reporting on it. We would also like to speed up the transition to renewables and phase out fossil fuel even more.

The charge that German carbon emissions are up because it is switching to coal is a popular meme in particular among the nuclear community. It is therefore important to set the record straight. Nuclear plants produce electricity, not liquid fuel, and the waste heat from nuclear plants is almost never used; apparently, not enough people want to live or work close enough to a nuclear plant to make the recovery of waste heat practical. The power sector is the easiest thing to fix. German carbon emissions largely come from heat and motor fuel, where too little is being done.

In a few weeks, the UBA should produce its own estimate of carbon emissions in the power sector, so we expect to be back with further confirmation of these findings soon. And keep in mind that we have estimated lower carbon emissions for 2014 as well from the power sector for various reasons, including most recently lower power exports to France, though the overall forecast for the power sector remains bleak until the end of the nuclear phaseout in 2022.
