New fuels and accompanying hikes in ticket prices will be essential to clean up air travel and avoid the worst effects of climate change, according to a new report.
Aviation is responsible for 5 per cent of global warming, and it is on track to power through a quarter of the planet’s annual carbon budget by 2050.
Despite some fledgling efforts to develop electric aircraft for short-haul flights, air travel is proving one of the most difficult sectors to decarbonise.In its analysis, European green transport group Transport and Environment (T&E) found that replacing fossil fuels in planes with “electrofuels” is the “only technically viable solution that would allow aviation to exist in a world that avoids catastrophic climate change”.

This will present a challenge to consumers as well as the industry, as the expense of these fuels means the cost of a plane ticket is projected to rise 58 per cent if they replace kerosene in all aircraft.

“The good news is that radically cleaner aviation is possible even with today’s technology,” said Andrew Murphy, aviation manager at T&E.
“Getting to zero starts with properly pricing flying and progressively increasing the use of sustainable synthetic fuels.
“There is a cost to this, but in light of how cheap subsidised air travel has become, and the incalculable cost of runaway climate change, it’s a price worth paying.”

As I noted in earlier posts about the Danish government’s plan to phase out diesel and gas cars by 2030, a full plan for emission reductions over the next 12 years would be revealed this week. And indeed it was. The plan is called “Together for a greener future.” This plan is the second of two parts. The first part was the “Energy — for a green Denmark” which was boosted considerably in the rare consensus by all parties in parliament in July where for instance the plans for adding 8 gigawatts (GW) of offshore wind power was tripled to 24 GW.

While Denmark is a pretty insignificant country in the scale of things, it was actually quite an achievement to reach bipartisan agreements on upping the game as opposed to the more common dismantling. I remember that Thomas L. Friedman played with an idea in his 2008 book “Hot, Flat and Crowded” where he imagined the US being China for just one day and how that could make so many rules come into effect, fast. Well, the current president is trying to do just that, but unfortunately he has yet to push rules on avoiding catastrophic climate change. My point is that it was very refreshing to witness this consensus in July, and it should serve as an example to countries with much bigger impact.

Growth in Japan’s solar power sector is predicted to slow over the coming decade, according to a new analysis from the Fitch Group, but not before the industry adds 17 gigawatts (GW) worth of new solar capacity between the end of 2017 and the end of 2020.

Urgent changes needed to cut risk of extreme heat, drought, floods and poverty, says IPCC

We’re getting there, aren’t we? We’re making the transition towards an all-electric future. We can now leave fossil fuels in the ground and thwart climate breakdown. Or so you might imagine, if you follow the technology news.

So how come oil production, for the first time in history, is about to hit 100m barrels a day? How come the oil industry expects demand to climb until the 2030s? How is it that in Germany, whose energy transition (Energiewende) was supposed to be a model for the world, protesters are being beaten up by police as they try to defend the 12,000-year-old Hambacher forest from an opencast mine extracting lignite – the dirtiest form of coal? Why have investments in Canadian tar sands – the dirtiest source of oil – doubled in a year?

The answer is, growth. There may be more electric vehicles on the world’s roads, but there are also more internal combustion engines. There be more bicycles, but there are also more planes. It doesn’t matter how many good things we do: preventing climate breakdown means ceasing to do bad things. Given that economic growth, in nations that are already rich enough to meet the needs of all, requires an increase in pointless consumption, it is hard to see how it can ever be decoupled from the assault on the living planet.

Offshore wind turbine giant MHI Vestas unveiled on Tuesday the world’s first commercially-available 10 megawatt (MW), marking the first time a “commercially-available” wind turbine has broken the double-digit barrier.

The offshore wind turbine capacity arms race has been driven into overdrive of late, with MHI Vestas breaking its own records, one after another, while GE Renewable Energy sits on the sidelines, safe in the knowledge that, when its 12 MW Haliade-X is installed in demonstration form sometime next year, it will have the world’s largest feet-wet offshore wind turbine.

MHI Vestas has been leading the way through 2018, however. The world’s most powerful currently operational wind turbines are the 8.8 MW v164 turbines installed at the European Offshore Wind Deployment Centre (EOWDC) in Aberdeen, Scotland, which was officially opened earlier this month. MHI Vestas has also been the owner of the world’s most powerful commercially available wind turbine thanks to its V164-9.5 MW turbines that passed their final certifications in June and have already been ordered and are expected to be installed by the end of 2019.
