The Rhodium Group, an independent research provider, estimates that, after a sharp uptick in 2018, US greenhouse gas (GHG) emissions fell by 2.1% This decline was due almost entirely to a drop in coal consumption. Coal-fired power generation fell by a record 18% year-on-year to its lowest level since 1975. Coal-driven decline.
Battery electric vehicles are only as clean as the energy source used to generate the electricity that powers them. These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions. Natural gas. from coal.
US electric power sector CO 2 emissions have declined 28% since 2005 because of slower electricity demand growth and changes in the mix of fuels used to generate electricity, according to the US Energy Information Administration (EIA). If electricity demand had continued to increase at the average rate from 1996 to 2005 (1.9%
Stroll, play, talk, celebrate -do whatever you want on the public street without sucking up gas fumes or fearing for your life from drunk drivers, texting drivers, drivers eating or putting on makeup or just plain dangerous behind the wheel lunatics. It’s long been time to kick coal out of L.A.’s
billion tonnes, their highest ever level, as the world economy rebounded strongly from the COVID-19 crisis and relied heavily on coal to power that growth, according to new IEA analysis. Coal accounted for over 40% of the overall growth in global CO 2 emissions in 2021, reaching an all-time high of 15.3 billion tonnes. billion tonnes.
Increased use of renewable energy will help reduce electricity generation from coal and natural gas power plants, according to the U.S. The EIA forecasts that wind and solar will together account for 16% of total electricity generation in 2023, up from 14% in 2022 and 8% in 2018.
Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. If biogas is substituted for conventional natural gas, total GHG emissions can further significantly reduced (190 gCO 2 /mile). Lifecycle GHG comparison.

Advanced biofuels, concentrated solar power (CSP), and solar photovoltaic power (PV) will see accelerating adoption and growth and are on track to change the global energy mix far earlier than is often assumed, according to a new report from The Boston Consulting Group (BCG). Cleaner coal through carbon capture and sequestration.
The system uses proprietary technology to autonomously orchestrate the lifting and lowering of the bricks, storing the potential energy in the elevation gain, and generating then discharging electricity as the bricks are lowered. DGF replaces the coal gasification used by others with biomass gasification and natural gas reforming.
by Michael Sivak, Sivak Applied Research The overall advantage of battery electric over gasoline vehicles, in terms of well-to-wheels emissions of greenhouse gases, has been well documented. However, the emissions of electric vehicles depend greatly on the energy source used to generate the electricity that powers them.
This year’s outlook is the first to highlight the significant impact that falling battery costs will have on the electricity mix over the coming decades. BNEF predicts that lithium-ion battery prices, already down by nearly 80% per megawatt-hour since 2010, will continue to tumble as electric vehicle manufacturing builds up through the 2020s.

million in a 50-megawatt parabolic trough concentrated solar power plant using molten salt energy storage in Torre de Miguel Sesmero, Badajoz, Spain. The GE unit and KGAL agreed to invest structured equity in Extresol II, developed by Spain-based ACS, Europe’s largest developer, builder and operator of solar thermal power plants.
The solution combines weather prediction and big data analytics to forecast accurately the availability of wind power and solar energy. This level of insight will enable utilities to better manage the variable nature of wind and solar, and more accurately forecast the amount of power that can be redirected into the power grid or stored.
All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. Wind beats coal by any environmental measure, but that doesn’t mean that its impacts are negligible. Source: Miller and Keith (2018a).
The Front-Loading Net Zero report states that electricity production costs could be reduced by up to 50% by 2050 if countries and states adopt 100% renewable systems faster than currently planned. The report says that carbon neutral systems can provide cheaper electricity compared to current fossil-fuel-based systems.
Renewables are expanding quickly but not enough to satisfy a strong rebound in global electricity demand this year, resulting in a sharp rise in the use of coal power that risks pushing carbon dioxide emissions from the electricity sector to record levels next year, according to a new report from the International Energy Agency.
In addition to its regional and temporal scope, this study is distinct from earlier LCA literature in four key aspects: This study considers the lifetime average carbon intensity of the fuel and electricity mixes, including biofuels and biogas.
An analysis of near-term spending plans on renewables by the biggest oil and gas companies shows that real investments in renewable energy will continue to pale in comparison to capex plans for greenfield fossil fuel projects. Indeed, much of Big Oil's reduction in greenhouse gas (GHG) emissions leans on the so-called natural gas bridge.
Florida utility Tampa Electric Co. has announced it will retire three coal units and double its solar output within two years. more… The post A Florida utility ditches coal, doubles its solar, and leaves out a big part of its story appeared first on Electrek.
Oil, gas and coal workers have all known for more than a dozen years that their work was helping to destroy people’s health and well being. So the justice I want to see is first, second and third for the victims in the sacrifice zones created by the oil, gas and coal companies. None of them are innocent bystanders.
Although all-electric vehicles (EVs) produce zero tailpipe emissions, there are upstream emissions of greenhouse gases from electricity production. Using electricity production data by source and state, the DOE’s Alternative Fuels Data Center has estimated the annual carbon dioxide (CO 2 e)-equivalent emissions of a typical EV.
In a new piece of research, BloombergNEF (BNEF) finds that the levelized cost of hydrogen (LCOH 2 ) made from renewable electricity is set to fall faster than it previously estimated. BNEF said that its updated forecast on the levelized cost of renewable electricity (LCOE) is the main driver of the drop in the LCOH 2 projection.
Even if you have 100 percent capture from the capture equipment, it is still worse, from a social cost perspective, than replacing a coal or gas plant with a wind farm because carbon capture never reduces air pollution and always has a capture equipment cost. In both plants, natural gas turbines power the equipment.
These facilities typically use approximately one ton of coal to produce one BBL of hydrocarbons, with a life cycle CO 2 emissions calculation that is slightly worse than equivalent fuels derived from conventional oil refining. DGF replaces the coal gasification used by others with biomass gasification and natural gas reforming.
Globally, ExxonMobil expects to see growth in plug-in hybrids and electric vehicles, along with compressed natural gas (CNG) and liquefied petroleum gas (LPG) powered vehicles. A growing share of the supplies used to meet liquid-fuel demand will come from deepwater, oil sands, tight oil, natural gas liquids and biofuels.
The United States used significantly less coal and petroleum in 2009 than in 2008, and significantly more wind power. There also was a decline in natural gas use and increases in solar, hydro and geothermal power according to the most recent energy flow charts released by the Lawrence Livermore National Laboratory. 22,09, 2.16
Oil accounts for most of this decline as, for the first time, global consumer spending on oil is set to fall below the amount spent on electricity. Global investment in oil and gas is expected to fall by almost one-third in 2020. Today’s investment trends are clear warning signs for future electricity security. —Dr Birol.
One of the common arguments you hear from people in America who are not fans of the idea of electric vehicles is that they are mostly charged from electricity produced from coal power plants. Heavy Coal Using States Accounted for Only 10% of EV Sales in 2020. of electric vehicle sales in the US. of sales.
The feed-stock reduction is achieved primarily by supplementing the process with oxygen and hydrogen produced by water electrolysis units that are powered by clean wind and solar generated electricity. DGF replaces the coal gasification used by others with biomass gasification and natural gas reforming.
In 2019, CO 2 emissions from petroleum fuels—nearly half of which are associated with motor gasoline consumption—fell by 0.8%, and CO 2 emissions from the use of natural gas increased by 3.3%. The United States now emits less CO 2 from coal than from motor gasoline. Total net electricity generation fell by 1.5%
The EMS (Earth and Mineral Science) Energy Institute at Penn State has developed a conceptual novel process configuration for producing clean middle-distillate fuels from coal with some algal input with minimal emissions. Principal inputs are coal, water, non-carbon electricity, and make-up solvent. EMS Energy Institute process.
The levelized cost of electricity analysis for H2 2015 shows onshore wind to be fully competitive against gas and coal in some parts of the world, while solar is closing the gap. Our report shows wind and solar power continuing to get cheaper in 2015, helped by cheaper technology but also by lower finance costs.
The US Energy Information Administration (EIA) has forecast in its January Short-Term Energy Outlook that rising electricity generation from clean energy such as solar and wind will reduce generation from fossil fuel-fired power plants over the next two years.
Deep declines in wind, solar and battery technology costs will result in a grid nearly half-powered by the two fast-growing renewable energy sources by 2050, according to the latest projections from BloombergNEF (BNEF). Electricity demand is set to increase 62%, resulting in global generating capacity almost tripling between 2018 and 2050.
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. Saudi Arabia burns up to 900,000 barrels of oil per day to generate over 50% of its electricity.
One possible scenario for the electricity system in the Western US in 2026-29. Under a range of resource cost scenarios, most coal power plants would be replaced by solar, wind, gas, and/or nuclear generation, with intermittent renewable sources providing at least 17% and as much as 29% of total power by 2030.
