U.S. energy use rises to highest level ever

In terms of original power sources (i.e. not electricity), the runaway leaders were petroleum and natural gas which between them took over two-thirds of the total share. Coal and nuclear were a distant third and fourth. Best of the rest was biomass at just over 5% of the total, easily more than wind and solar combined.

Americans used more energy in 2018 than in any other year, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory (LLNL).

Overall total energy consumption rose to 101.2 quadrillion BTU (or “quads”), reports TechXplore. The prior record, set in 2007, was 101.0 quads.

Energy use went up by 3.6 percent from 2017, which also is the largest annual increase since 2010.

‘Sustainable’ aviation fuels – more pie in the sky

Land-grown biofuel is in enough trouble already as an enemy of the environment. But the vain pursuit of the imaginary CO2 enemy leads to numerous bad policy decisions.

“Hydrocarbon fuels will remain essential for modern air travel. So-called sustainable aviation fuels are expensive, produced in negligible volumes, and provide CO2 savings only on paper. As such, they fail the real sustainability test of affordability, plenty, and reliability.”

Air travel is a miracle of our modern society, writes Steve Goreham at MasterResource.

Project to test feasibility of sail-powered biomass shipping

Whether this is anything more than a publicity stunt remains to be seen. Biomass burning will still be producing more CO2 at the point of use per unit of energy than the coal it replaced.

Drax, operator of the UK’s largest power station, is partnering with the Smart Green Shipping Alliance (SSGA), leading dry bulk cargo transporter Ultrabulk, and Humphreys Yacht Design to tackle the mounting issue of CO2 emissions from the shipping industry, reports GreenCarCongress.

A £100,000-, 12-month feasibility study funded by InnovateUK, the Institution of Mechanical Engineers (IMechE) and private investors has begun, which will examine the potential of fitting the innovative sail technology Fastrig onto Ultrabulk ships importing biomass into the UK for cutting both carbon emissions and costs.

The shipping industry emits roughly 3% of global CO2 and other greenhouse gas emissions (CO2-equivalent), or approximately 1 billion tonnes of CO2 and other GHGs per year—more than twice as much as the UK’s total emissions, from all sources.

Europe’s renewable energy directive poised to harm global forests, say experts

Whether wood is truly renewable or not is a matter of opinion. Trees can be burnt in minutes but regrowth obviously takes many years. Theory has it that new trees can over time recover the carbon dioxide from tree burning but how realistic is that? Not very much, according to experts. The same politicians who attend climate conferences proclaiming ’emissions’ are a terrible problem now actively support making them worse. You couldn’t make it up.

Europe’s decision to promote the use of wood as a “renewable fuel” will likely greatly increase Europe’s greenhouse gas emissions and cause severe harm to the world’s forests, according to a new paper published in Nature Communications.

European officials on final language for a renewable energy directive earlier this summer that will almost double Europe’s use of renewable energy by 2030.

Against the advice of 800 scientists, the directive now treats wood as a low-carbon fuel, reports Phys.org, meaning that whole trees or large portions of trees can be cut down deliberately to burn.

Can CNG trucks go the distance?

The idea here is that high pressure carbon-fibre fuel tanks should help to demolish the ‘range anxiety’ of truck operators who need to cover big distances daily, by giving a range of upto 500 miles. America already has some, but these are the first in Europe. Lifetime costs should be lower than regular trucks, but the report doesn’t say where the ‘renewable biomethane‘ fuel is coming from.

Delivery trucking is a dirty business, but the companies that rely on it are working to clean things up – and compressed natural gas is emerging as a useful alternative to our reliance on diesel power.

In the UK, Scania has created a fleet of biomethane fueled trucks for Waitrose, which is looking to reap the rewards with lower running costs and less emissions, reports New Atlas.

Algal biofuel dream turns out to be a damp squib

Another green dream has crumbled in the face of inconvenient reality, defeated by biology, as Yahoo News reports. Research shows it is neither commercially nor environmentally sustainable, unless the equivalent of three Belgiums and a mountain of fertilizer can be found.

Modern biofuels have been touted as a greener alternative to petrol and diesel since the early 1900s. It seems like a good idea on paper, and they do work – but their use and production doesn’t come without problems.

The first generation of biofuels – mainly ethanol made from plant crops – and second generation, derived from plant and animal waste streams, both had environmentalists and others concerned about the competition for land and nutrients between biofuels production and food production.

It was with a lot of hope, and hype, that production of the third generation of biofuels was started. Unlike their predecessors, these biofuels are derived from algae, and so in theory the food vs fuel dilemma of crop-based biofuels would be solved.

Fossil fuel oil and gas originated from ancient algae in large measure, so the concept here is to replicate the essence of the creation of fossil fuels, albeit accelerated and optimised with modern chemical engineering. It was claimed that using algae would be much more efficient than creating biofuels from terrestrial plants and that the technology would make use of poor quality land not able to grow other crops.

Climate of unintended consequences – NYT

Bret Stephens at The New York Times delves into the erroneous ‘climate-friendly’ image of biofuels, and questions the claimed success of renewables in general. Not new criticisms, but new for the NYT at least.

A few extracts from the piece:
“Converting biomass feedstocks to biofuels is an environmentally friendly process. So is using biofuels for transportation. When we use bioethanol instead of gasoline, we help reduce atmospheric CO2.”

These confident assurances come from “Biofuels: A Solution for Climate Change,” a paper published in 1999 by the Clinton administration’s Department of Energy. Feels a little dated in its scientific assumptions, doesn’t it?

Biofuels increase, rather than decrease, carbon dioxide emissions: study

For how much longer?

Promoters of biofuel are running out of excuses for converting vast tracts of valuable farmland into fuel sources, as this Phys.org report shows. This non-solution to a debatable problem needs reviewing urgently.

A new study from University of Michigan researchers challenges the widely held assumption that biofuels such as ethanol and biodiesel are inherently carbon neutral.

Contrary to popular belief, the heat-trapping carbon dioxide gas emitted when biofuels are burned is not fully balanced by the CO2 uptake that occurs as the plants grow, according to a study by research professor John DeCicco and co-authors at the U-M Energy Institute.

The US Renewable Fuel Standard: “Set up for fraud”

One fraudster’s toy

Reporter Marita Noon lifts the lid on various cases of biofuel fraud in the US.

America’s rush to renewables has invited corruption and fraud. Researcher Christine Lakatos and I, together, have produced the single largest body of work on green-energy crony-corruption.

Our years of collaboration have revealed that those with special access and influence have cashed in on the various green-energy programs and benefitted from the mandates, rules, and regulations that accompany the huge scheme.

Forest-destroying palm oil powers cars in EU: report

Another so-called green policy is coming under increasing fire, as Yahoo News reports. EU ignores critics.

Paris (AFP) – Palm oil produced on tropical plantations that drive deforestation has become a major biofuel for vehicles in the European Union, industry figures released Tuesday by an environmental group revealed.

In 2014, nearly half of the palm oil used in Europe wound up in the gas tanks of cars and trucks, according to data compiled by the EU vegetable oil industry association Fediol, and obtained by Brussels-based NGO Transport & Environment.

Bad Biodiesel Beancounting Busts Biofuel Benefit Budget

From Nature:

The European Union (EU) has spent the past 10 years nurturing a €15-billion (US$20-billion) industry that makes transport fuel from food crops such as soya beans and sugar cane in the hope of cutting greenhouse-gas emissions. Yet for more than half a decade, scientists have warned that many food-based fuels might actually be boosting emissions relative to fossil fuels.

The original accounting for biofuel emissions was all wrong, as Tim Searchinger, who studies environmental economics at Princeton University in New Jersey, noted in an influential 2008 article (T. Searchinger et al. Science 319, 1238–1240; 2008). He and his colleagues found that when agricultural land is used to plant biofuel crops, fresh land may be ploughed up to accommodate the existing crops that have been edged out. Ultimately, that may drive clearing of forests, peatlands and wetlands rich in sequestered carbon — causing large emissions of carbon dioxide. “It’s kind of obvious if you think about it,” says Searchinger.
