In addition to high oil prices and the financial crisis, the increased use of new renewable energy sources, such as biofuels for road transport and wind energy for electricity generation, had a noticeable and mitigating impact on CO 2 emissions. Biofuels and other renewable energy sources start impacting CO 2 trends.
In October 2001, the group announced an agreement with Swedish startup H2 Green Steel. Electricity from renewable sources and its use in production of hydrogen from electrolysis are key elements of the transformation. This green hydrogen will replace the coal currently used in the conventional blast-furnace process.
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 carbon intensity of California’s economy has dropped 38% since the 2001 peak and is now one-half the national average. metric tons per person in 2016 (roughly equal to driving 26,000 miles).
The HBI can be used in electric arc furnaces (EAF) to replace scrap metal or in blast furnaces to replace coke (produced from coal) and iron ore. Conversion to green hydrogen from renewable energy sources will take place once available in sufficient quantities and at an economical cost. Earlier post.).
They used a lot more coal than they originally admitted to, several hundred million tons more. Another major shift is that China has become a voracious energy importer, especially of coal and liquefied natural gas. Like the United States, China has become among the world’s largest importers of oil, gas and coal.
Specific circumstances, such as the very warm fourth quarter of 2015 and relatively low natural gas prices, put downward pressure on emissions as natural gas was substituted for coal in electricity generation. Coal’s share of total electricity generation in the power sector fell from 54% in 1990 to 34% in 2015.
a Fischer-Tropsch process company, plans to build a plant in Rialto, California for the production of synthetic fuels and electric power from renewable waste biomass feedstocks. The carbon footprint of the plant is designed to be near zero as the fuels and power would be produced only from renewable feedstocks. Rentech, Inc. ,
Examining the role of shale gas, PwC’s report suggests that at current rates of consumption, replacing 10% of global oil and coal consumption with gas could deliver emissions savings of around 3% a year (1gt CO 2 e per annum). And governments’ support for vulnerable communities needs to consider more drastic actions.
The continent was mostly powered by locally mined coal until the 1950s, when imports of cheap Middle Eastern oil started transforming the energy picture. Since 2001, though, only the Norwegian gas output has kept on growing. The drop was steep enough to force Germany to produce more electricity from coal than from wind in 2021.
Indeed I am talking about Big Dick Cheney, who in addition to his many other immoral and criminal acts also shamelessly promoted the excessive use of oil, coal, gasoline and other fossil fuels by encouraging Americans to use all the energy they could afford to put on their credit cards. The Big Dick Cheney Effect.
With oil prices surging in the summer of 2008, the annual increase in global emissions of carbon dioxide (CO2) from oil, coal, gas and cement production appear to have halved according to preliminary estimates by the Netherlands Environmental Assessment Agency. Who said no good has come from the global financial crisis? per cent in 2007.
Plug-In Hybrids Are Cleaner (Even on a Coal Grid) [ to top ] This entire section is finally obsolete -- because we now have a definitive study by the Electric Power Research Institute and the Natural Resources Defense Council. Three more points: Both reports match up well with previous studies. The GREET 1.6

The American Lung Association oversees the Clean Air Choice program throughout the United States promoting alternative renewable fuels such as biodiesel and E85, partnering with fleets to replace legacy diesel engines, and by supporting the clean-air advantages of electric and hybrid vehicles. —Harold P.
9 ] In addition, the complex, deliberate, and lengthy publishing cycle of the IPCC’s Assessment Reports—which have so far been produced in 1990, 1995, 2001, and 2007—has not kept pace with the abrupt acceleration of many key indicators of climate change. ” [ 18 ].
