The causes of the recent decrease in US greenhouse gas emissions

Since their peak in 2007 GHG emissions in the USA have decreased more in absolute terms than in any other country. The results of this review suggest that approximately 40% of this decrease was caused by the replacement of coal with gas in generating plants, 30% by improvements in the efficiency of internal combustion engines and 30% by growth in low-carbon renewables. Another major contributor was the 2008-9 global recession, although its impact can’t reliably be quantified. Had economic growth continued at historic rates between 2007 and the present US GHG emissions would now be substantially higher than they are. Continue reading

The Changing Face of UK Power Supply

UK Grid Graphed provides a graphic summary of daily, monthly and annual UK electricity generation from 2012 to 2015 based on BM Reports as archived by Gridwatch. This post provides an overview of the UK Grid Graphed resource and the key observations to be made from the data. In summary, coal generation is in steep decline to be substituted by rising wind, solar, biomass and exports. Demand for electricity is also falling and government should be concerned about the extent that this is caused by rising electricity prices and policy. Continue reading

Greek Tragedy

After several years, several months, several weeks and several days of crisis, it looks like things are about to come to a head for Greece and its banks. It becomes easier to understand exactly what GREXIT may mean for the Greek people. What happens when the banks and the government run completely out of money? Continue reading

Global Energy Trends – BP Statistical Review 2015

The BP Statistical review of World Energy was published on Wednesday 10th June. Last year I published a short post summarising Global Energy Trends and this post up-dates those charts with the newly published data for 2014. Continue reading

Blowout week 74

The usual mix below the fold, including shale oil, the coal crisis in Germany, Austria now to sue the Czech Republic over nuclear, the doomed city of Hull, Exxon’s CEO speaks out on renewables, a solution to the energy storage problem, biofuels and water use, vanishing glaciers on Everest, an ice cream that increases climate change awareness and immediately following, are the EIA’s oil production numbers reliable? Continue reading

Blowout Week 62

Drawing one of the strongest links yet between global warming and human conflict, researchers said Monday that an extreme drought in Syria between 2006 and 2009 was most likely due to climate change, and that the drought was a factor in the violent uprising that began there in 2011.

UK Electricity Supply, Christmas 2014

On Christmas Day, children began opening their presents at around 05:00 am in the UK. As the excitement gathered pace, the country’s coal power stations were fired up providing 38% of all the electricity consumed. Nuclear hummed along all day providing a steady 8 GW and 26% of the total. Clean burning natural gas was demoted to third place providing just 14% of the total whilst providing a significant share of the load balancing service. Coal, nuclear and natural gas combined provided 78% of UK electricity on Christmas Day. Continue reading

Oil and Coal: trends in global energy substitution

The percentage contributions of oil and coal tend to move in opposite directions. Coal goes down, oil goes up. Oil goes down, coal goes up. Oil goes flat, so does coal. But neither oil nor coal show a clear overall relationship with the third major source of energy, natural gas. The suggestion is that oil and coal have been substituting for each other, with coal replacing oil or oil replacing coal depending presumably on market conditions at the time, but with gas remaining largely unaffected. Continue reading

Cycling Coal to Balance Electricity Grids

And so the question is if a coal fired power station is “switched off” when demand for coal fired electricity goes down are the furnaces extinguished thus eliminating CO2 emissions or are they kept burning, perhaps at reduced levels?

I have always felt the best way to tackle both emissions and energy scarcity was to improve energy efficiency at every level of society. The current strategy appears to be taking us in the opposite direction. Continue reading

Energy and Mankind part 3

If you look back at the history of Energy and Mankind, in 1950, nuclear power was the energy source of the future. The only power source that could not just rival FF but was superior to it. The future has not yet arrived and we need to hope that it has not been cancelled altogether. Continue reading

Global Energy Trends – BP Statistical Review 2014

In 2003, FF accounted for 87% of global primary energy consumption. In 2013, FF accounted for 87% of global primary energy consumption. This is testimony to the absolute failure of energy policies aimed at reducing CO2 emissions. Continue reading

China – the coal monster

In 2012 China consumed 50.4% of all coal produced on Earth. Most, but not all of that coal was produced in China, mainly from deep underground mines. Like Europe and the USA before it, China’s industrial revolution has been founded on coal that accounts for 68% of all energy consumed. Continue reading

Germany: energiewende kaput?

The penetration of wind energy in 2012 was 3.4% and solar 2.1% of total energy consumed and I would judge that this is too low a level of penetration from which to draw any conclusion about the success or failure of the energiewende. This in itself is a problem. Huge investment and publicity so far has produced rather little in return. Continue reading

Coal and the IPCC

The IPCC’s coal burn is enormous, twice the world reserves by 2100, and seven times reserves by 2500. Coal so dominates that it is not an exaggeration to say that the IPCC and climate-change research programs depend on this massive coal burn for their existence. Continue reading
