A Chinese Carbon Bubble?

While China’s coal consumption growth has slowed down, coal capacity still grows. This has led some to conclude that China’s coal consumption growth will resume. But continued buildup of coal-fired plants represents an investment bubble that will burst as overcapacity becomes too large to ignore.[read more]

Off the Well-Trodden Path: Where are the Hidden Solar PV Growth Markets?

February 20, 2015 by Roman Kilisek

Hidden PV Markets

According to the International Renewable Energy Agency, the US has the “potential to lead the global transition to renewable energy. It has some of the best renewables resources in the world.” Perhaps even more important in this context is that the US is deemed to also have “a vibrant culture of innovation."[read more]

For the first time this century China’s coal consumption has fallen, according to data from both the Chinese Coal Industry Association and the National Energy Administration. The amount remains in question, with the Coal Industry Association reporting around 3.5% but NEA data showing a fall of only 0.4%.[read more]

China Coal Use Can Peak this Decade: What Did the IEA Miss?

December 22, 2014 by Lauri Myllyvirta

China Peak Coal and the IEA

The IEA published its Medium-Term Coal Market Report, with a lot of attention devoted to proffering the notion that China’s coal consumption will continue to grow until the end of this decade. A thorough analysis of Chinese energy trends suggests that coal peak is much more achievable than the IEA made it seem.[read more]

Analyzing IEA Forecasts

This article takes a look at the accuracy and consistency of International Energy Agency forecasts by comparing a range of historical forecasts with actual data. The largest deviations are observed when looking at oil, coal and renewables other than hydro.[read more]

Utilizing GIS for Renewable Energy Projects

November 15, 2014 by Dan Liggett

GIS and Renewables

Your renewable energy infrastructure projects are far too expensive to make random decisions on siting. For many reasons – not the least of which are cost, efficiency and productivity – siting should be as exact as the science behind renewable energy itself.[read more]

Energy Future and Sustainability

If the rate of ocean heat uptake is the most fundamental single measure of the state of Earth’s climate, then ocean thermal energy conversion using a heat pipe is the single hope for an energy rich sustainable future, given, as I believe is the case, 97 percent of climate scientists are right.[read more]

New England Relying More on Natural Gas Along with Hydroelectric Imports from Canada

August 31, 2014 by U.S. EIA: Today in Energy

New England Energy Resources

Electric operators in New England have been both generating more electricity from natural gas and importing more hydroelectric generation from Quebec over the past decade. These two sources of electricity are displacing the use of coal and oil as generation fuels in New England.[read more]
