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. An increase in natural gas generation offset some of the climate gains from this coal decline, but overall power sector emissions still decreased by almost 10%.
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. In the journal Joule , Harvard researchers report the most accurate modelling yet of how increasing wind power would affect climate.
Coal trains and terminal operations add a significant amount of fine particulate matter (PM 2.5 ) pollution to urban areas—more so than other freight or passenger trains— according to a study conducted in Richmond, California, by the University of California, Davis. The results indicate coal trains add on average 8.32
A study by researchers at Harvard University and Tsinghua University shows that there is enough wind in China to generate electricity to supply the nation's entire projected demand for 2030 (about twice what is used now) at reasonable prices per kilowatt-hour. Nielsen, Yuxuan Wang (2009) Potential for Wind-Generated Electricity in China.
The partners aim to replace coal-fired power plants with hydrogen-ready gas-fired power plants in Germany, and to build production of low carbon and renewable hydrogen in Norway that will be exported through pipeline to Germany. Germany has an ambition to phase out all coal fired power plants by 2030.
The solution combines weather prediction and big data analytics to forecast accurately the availability of wind power and solar energy. By utilizing local weather forecasts, HyRef can predict the performance of each individual wind turbine and estimate the amount of generated renewable energy.

Earlier post.). and Hitachi, Ltd.
New investment in wind, solar, and other clean energy projects in developing nations dropped sharply in 2018, largely due to a slowdown in China. This is due to wind and solar projects generating only when natural resources are available while oil, coal, and gas plants can potentially produce around the clock. thousand in 2017.
The arrival of cheap battery storage will mean that it becomes increasingly possible to finesse the delivery of electricity from wind and solar, so that these technologies can help meet demand even when the wind isn’t blowing and the sun isn’t shining. trillion of that going to wind and solar and a further $1.5
In August 2012, coal produced 39% of US electricity, up from a low of 32% in April 2012, when the natural gas share of generation equaled that of coal. The August coal share of generation is still notably lower than the 50% annual average over the 1990-2010 period. Other plants use PRB coal transported by rail.
” “ Some have even suggested that coal state representatives in Washington should block any advancement of national health care reform legislation until the coal industry’s demands are met by the EPA, ”, wrote Byrd. West Virginia is home to about 22,000 coal miners, down from 62,500 in 1979.
Fortum has developed the Joddböle area since the dismantling of its Inkoo coal-fired power plant there in 2017-2020.

Runoff from pavement with coal-tar-based sealant is the primary source of toxic polycyclic aromatic hydrocarbons (PAHs) to streambed sediments in Milwaukee, Wisconsin, according to a US Geological Survey and Milwaukee Metropolitan Sewerage District open-access study published in the journal Environmental Toxicology and Chemistry. Magruder, C.
The magnitude of these savings is ~5% to 15% higher in a system with 20% wind penetration compared to a system with no wind power, and the savings are 50–60% higher in a system that requires capacity expansion. Controlled charging can also take advantage of the high levels of wind generation that commonly occur at night in the US.

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.
The power sector has become less carbon-intensive as natural gas-fired generation displaced coal-fired and petroleum-fired generation and as the noncarbon sources of electricity generation—especially renewables such as wind and solar—have grown. In 2005, noncarbon sources accounted for 28% of the US electricity mix.
Oil demand grew by less than 1%—the slowest rate amongst fossil fuels—while gas grew by 2.2%, and coal was the only fossil fuel with above average annual consumption growth at 5.4% Coal was again the fastest growing fossil fuel with predictable consequences for carbon emissions; it now accounts for 30.3% globally, and 8.4%
Other key findings from the May 2022 STEO forecast include: Solar and wind power will provide 11.1% Solar and wind are the only energy sources that will increase their share of US electricity generation this summer. US coal production will total 598 million short tons in 2022, which is a 3% increase from 2021. in summer 2021.
The Los Angeles Department of Water and Power (LADWP) has taken steps to transition out of the use of coal-fired electricity earlier than mandated by California state law. LADWP currently owns a 21% interest in the 2250 megawatt (MW) Navajo Generating Station, receiving 477 MW of coal-fired power from the plant.
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.

DOE Funding: $1,499,997. DOE Funding: $1,483,787.
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. Only when wind replaced coal itself did social costs decrease.

Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT. The first two reports dealt with nuclear power (2003) and coal (2007).

Ignite Energy Resources (IER), developer of a supercritical water technology, and TRUenergy have entered into a Memorandum of Understanding (MoU) to develop a commercial demonstration plant that will apply IER’s direct coal-to-oil and upgraded dry coal process to the brown coal at TRUenergy’s Yallourn mine in Australia.
Significant cost reductions can be achieved by front-loading the deployment of renewables, mainly wind and solar photovoltaic, and by utilizing the technologies needed to balance their inherent intermittency, such as energy storage and thermal balancing power plants.
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.
