While oil will remain the most widely used fuel, overall energy demand will be reshaped by a continued shift toward less-carbon-intensive energy source as well as steep improvements in energy efficiency in areas such as transportation, where the expanded use of advanced and hybrid vehicles will help push average new-car fuel economy to 48 mpg (4.9
Biocoal exhibits the same energy density and material handling properties as coal, but unlike coal, it is carbon-neutral, contains no heavy metals, and produces less ash, smoke and volatile off-gases. Figure of person provided for scale. Locomotive 3463. Click to enlarge.
Syngas can be made in many ways, but one of those, methane dry reforming, is increasingly important because the chemical inputs are methane and carbon dioxide, two potent and problematic greenhouse gases. Syngas is a mix of carbon monoxide and hydrogen gas that can be made from coal, biomass, natural gas and other sources.
Although population-dense cities contribute less greenhouse-gas emissions per person than other areas of the country, these cities’ extensive suburbs essentially wipe out the climate benefits, according to a new study by Christopher Jones and Daniel Kammen at UC Berkeley. —Jones and Kammen.
Electra has raised $85 million to produce Low-Temperature Iron (LTI) from commercial and low-grade ores using zero-carbon intermittent electricity. Electra’s process emits zero carbon dioxide emissions and carries zero green premium, meaning it will cost the same or less than existing production methods powered by fossil fuels.
The collapse in world oil prices in the second half of 2014 will have only a moderate impact on the fast-developing low-carbon transition in the world electricity system, according to research firm Bloomberg New Energy Finance. However, the slump in the Brent crude price per barrel from $112.36 on 30 June to $61.60
In an opinion piece in the journal Nature , a team from the US and Europe suggests that the transition to a low-carbon world will create new rivalries, winners and losers, and that it is therefore necessary to put geopolitics at the heart of debates about the energy transition. abating carbon will create losers.
The US Energy Information Administration (EIA) has released a new report, State-Level Energy-Related Carbon Dioxide Emissions, 2000-2010. The report shows a significant variation of energy-related carbon dioxide emissions across states on both an absolute and a per capita basis. tonnes of CO 2 per person), followed by North Dakota (80.4
You think HE’s working very hard to end our nation’s sick addiction to carbon based fuels that kill people and destroy our civilization? I’m thinking he likes our carbon-based economy just the way it is. It’s the 2nd biggest product Exxon/Mobil and their pals in the oil, coal and gas industries pump out.
In addition, we have used our judgment about timing and extent of commercialization of carbon capture and sequestration (CCS) to describe our scenario with CCS (CIS and AIS assume no CCS). It is reduced by 900 Mtce to 4600 Mtce in AIS in 2050, a cumulative energy reduction of 26 billion tonnes of coal equivalent from 2005 to 2050.
Senate Bill 32, signed in 2016, requires the state to go even further than AB 32 and cut greenhouse gas emissions 40% below 1990 levels by 2030—the most ambitious carbon goal in North America. They fell 23% from a peak of 14 metric tons per person (roughly equal to driving 34,000 miles) in 2001 to 10.8
The outlook is developed by examining energy supply and demand trends in 100 countries, 15 demand sectors covering all manner of personal and business needs and 20 different energy types. Progress on curbing carbon dioxide emissions through 2040 will be led by OECD nations as energy demand declines and a shift to lower-carbon fuels occurs.
At the same time, energy efficiency gains and increased use of renewable energy sources and lower carbon fuels, such as natural gas, are expected to help reduce by half the carbon intensity of the global economy. Natural gas remains challenged as a fuel for most personal vehicles. Source: ExxonMobil. Click to enlarge.
of carbon dioxide (CO 2 ) emissions in the US. Electrification will reduce emissions, with the scale determined by the carbon intensity of the power sector. All three options are likely to lead to emissions reductions relative to ICE vehicles, but the amount will depend critically on the carbon intensity of the electricity supply.
Assuming no changes in policy related to greenhouse gases, carbon dioxide emissions grow slowly, but do not again reach 2005 levels until 2027. quadrillion Btu projected in the AEO2010 Reference case, due to relatively lower disposable personal income. —EIA Administrator Richard Newell. quadrillion Btu in 2009 to 3.1
While the mix shifts toward lower-carbon-intensive fuels, the world will need to pursue all economic energy sources, the report says. As personal mobility increases, average new-car fuel economy (including SUVs and light trucks) will improve as well, rising from about 30 miles per gallon (7.83 Energy & Carbon Summary.
Qiang Dai and Christian Lastoskie found that BEVs and FCVs in particular offer significant reductions in greenhouse gas emissions, especially if carbon capture and sequestration (CCS) technologies are implemented at the fuel conversion facilities. —Dai and Lastoskie. The system boundary for the LCA. particulate matter formation (PMF).
Personal air travel (billion seat-miles) grows by an average of 0.7% Natural gas overtakes coal as the largest fuel for US electricity generation. In some areas, natural gas-fired generation replaces power formerly supplied by coal and nuclear plants. Energy demand for aircraft grows in the AEO2014 Reference case from 2.5
ExxonMobil projects that meeting future energy demand will be supported by more efficient energy-saving practices and technologies; increased use of less-carbon-intensive fuels such as natural gas, nuclear and renewables; as well as the continued development of technology advances to develop new energy sources. Energy-related CO 2 emissions.
Data centers use so much concrete that the construction boom is wrecking tech giants’ commitments to eliminate their carbon emissions. Even though Google , Meta , and Microsoft have touted goals to be carbon neutral or negative by 2030, and Amazon by 2040, the industry is now moving in the wrong direction.
Specifically, the authors found that while demand for gas from the residential sector decreases as electrification progresses, because of the planned phasing-out of coal and nuclear generation and limited increase of renewables, overall gas demand rises in the power market.
The drawback to these technologies is that fossil fuels (principally oil and coal) are still used to produce the electricity that powers these vehicles, thereby eliminating some of the potential gains. Power said, more important are the personal financial implications of deciding to purchase an alternative-energy vehicle.
It’s been weakened and dumbed down by carbon-loving Democrats and the entire Republican Party and it’s not the bill it should be. But it’s far better than no bill or the homage to fossil fuels the GOP has embraced like the sellouts and carbon collaborators they are. This climate bill is an essential first step.
personal device—portable emergency hydrogen refueler that can be carried onboard the fuel cell electric vehicle, such as in the trunk, easily handled by the driver, and able to provide hydrogen to at least one stranded vehicle. The second is a.
Stuart Licht ( earlier post ) have developed a new process that transforms CO 2 into a controlled selection of nanotubes (CNTs) via molten electrolysis; they call the process C2CNT (CO2 into carbon nanotubes). Molten carbonate electrosynthesized boron-doped CNTs exhibit high electrical conductivity. —Ren et al. Licht (2017).
By MaltaGC – Own work, CC BY-SA 4.0, [link] The UK has marked a historic moment in its energy transition by shuttering the Ratcliffe-on-Soar Power Station in Nottinghamshire, its last remaining coal power plant. The UK predominantly replaced coal with wind and solar, without increasing reliance on gas. billion in costs.
Without a bold change of policy direction, the IEA warned at the launch, the world will lock itself into an insecure, inefficient and high-carbon energy system. The use of coal—which met almost half of the increase in global energy demand over the last decade—rises 65% by 2035. Other Findings from WEO 2011.
Photo: PSNH/Flickr Both of New Hampshire’s coal plants are shutting, making New England the second coal-free region in the US. The Bow, New Hampshire-based power station has committed to retiring the coal-burning units at Merrimack and Schiller Stations in New Hampshire, by 2028 and 2025, respectively. Get started here. –ad*
Photo: China News Service Renewable energy costs in Asia last year were 13% cheaper than coal and are expected to be 32% cheaper by 2030, according to a new study. This is significant because it marks a shift toward making renewables increasingly competitive with coal, a mainstay in APAC’s energy mix. Get started here. –
Projected growth in world carbon dioxide emissions. World carbon dioxide emissions are projected to rise from 29.0 In non-OECD Asia, for example, the reference case projects that energy use for personal motor vehicles (light-duty cars and trucks, as well as two- and three-wheel vehicles) will increase by 3.6% Source: IEO2009.
It’s not sexy and it doesn’t make a bunch of old school, balding, white, male, carbon collaborators stinking filthy rich, so it’s no wonder they’ve done every evil and despicable thing in their power to keep this weapon from being aimed at them. Won’t that be fun?! The Big Dick Cheney Effect.
However, some critics argue that EVs still have a significant carbon footprint, particularly due to battery production and electricity generation. In regions relying on coal and fossil fuels , EVs still produce fewer emissions than gasoline cars, but the difference is smaller. So, are EVs truly greener?
In countries like Australia, our data suggests that hybrids can have a greater impact than full electrification in getting carbon off the road.” He went on to point out that that EVs were “powered, in many cases, by electricity generated from coal” and that they remained “impractical” for drivers.
Between 2006 and 2015, California’s GDP per capita grew by almost $5,000 per person, nearly double the growth experienced by the US as a whole. California has experienced tremendous success implementing policies that incentivize innovation in business, technology and carbon reduction. below their 2006 levels.
We'll be interested in how much carbon-based fuels such as coal and natural gas went into the electrical energy that charged our batteries. Personally, I won't miss the smell of nitromethane at all. For them, recharge efficiency might be just as important as MPGe rating. Electric dragsters will undoubtedly improve on that.
With all this, consumers and policymakers alike are hopeful that society will soon greatly reduce its carbon emissions by replacing today’s cars with electric vehicles. 70 percent of lithium-ion batteries are produced in China, which derived 64 percent of its electricity from coal in 2020. But coal use varies, even within China.
There are four guidelines to follow: Refrain from using or burning oil, gas or coal. However, if an EV is charged using electricity that is generated by burning coal or in some other way that generates fossil fuel emissions, those emissions would be associated with that EV’s well to wheel emissions. Attend an online or in-person event.
The average person who drives 40 miles per day or less wouldn't use any gasoline at all ," he says. While an average person might fill the tank with gasoline about 35 times a year, a plug-in would require perhaps six times. The only time would be on weekend trips and vacations across country."
A catalytic converter , for example, uses palladium, rhodium, and platinum to convert pollutants like carbon monoxide, nitric oxide, and nitrogen dioxide into water and carbon dioxide. We have various electronic communication networks (the autocatalytic system) and some early personal computers (the catalyst).
The long-range goals of the Partnership focus on a transition to a highway transportation system that uses sustainable energy resources and reduces emissions, including net carbon emissions, on a lifecycle or well (source)-to-wheels basis. Methods for the recycling of carbon-reinforced composites need to be developed.
There are two major reasons for this: first, EVs are not going to reach the numbers required by 2050 to hit their needed contribution to net zero goals , and even if they did, a host of other personal, social and economic activities must be modified to reach the total net zero mark. For example, researchers at University of Oxford in the U.K.
Rising long-term natural gas prices, the high capital costs of new coal and nuclear generation capacity, state-level policies, and cost reductions for renewable generation in a market characterized by relatively slow electricity demand growth favor increased use of renewables. Transportation. quadrillion Btu (13.8 quadrillion Btu (13.5
So what I’m seeing as a result of what you’re telling me If there was a smart politician down south here there is a wide open position for the person who wants to lead the cavalry charge down here. THE HOLY GRAIL OF SOLAR: $3 A WATT, CHEAPER THAN COAL. And at sub $3 you’re cheaper than coal. All of a sudden it was on fire.
and illuminating look at how a simple policy shift could rattle everything from personal budgets to the red-blue map. The study doesn’t try to declare a tax policy utopia; it skips the moralizing and dives into the mechanics of who wins and who loses if we make this swap. In the end, it’s a wonky (this is a compliment!)
