Drought and Hydopower Impacts

The diminished hydropower capacity of California’s dams cost electricity customers a total of $1.4 billion in the past three years, according to a study from the Pacific Institute. When the 2007 to 2009 drought is taken into account, the figure rises to $2.4 billion.[read more]

Putting Renewable Energy Growth into Perspective

Wind, solar, biomass and other renewable electricity sources grew by 103 gigawatts in 2014, and for the first time in decades, fossil energy's share of world electricity production is declining. Has the great Clean Energy Stagnation of the past three decades finally come to an end?[read more]

As California Loses Hydro Resources to Drought, Large-Scale Solar Fills Gaps

April 3, 2015 by Stephen Lacey

In 2013, yearly electricity generation from solar trailed every renewable energy technology in California except small hydro. But over the course of a year, solar generation more than doubled in the state, making it the second-biggest provider of renewable electricity in 2014 behind wind.[read more]

Power Can Be Both Clean and Reliable

A number of analysts have raised concerns that the proposed Clean Power Plan, aimed at reducing power plant carbon emissions, could threaten the reliability of electric power. But a closer look at the U.S. power system and the safeguards in place suggests that these reliability issues are manageable.[read more]

Electricity Saving Campaign in Brazil Obscures Energy Challenges

March 19, 2015 by Anthony Venezia

Brazil and Energy Challenges

The once electric buzz surrounding the prospect of Brazil as an emerging market powerhouse is no more. International investors are losing their taste for the country and it’s weakening economy, remarkable considering just a few short years ago Brazil was heralded as a harbinger of a new global economic order.[read more]

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]

Batteries Shmatteries: Let's Talk About the Biggest Type of Solar Storage

Solar and Storage Innovation

In talking about energy storage, the renewable energy industry usually thinks batteries, with few being aware of a much more powerful source of storage that can be integrated with intermittent sources of power like sun and wind: pumped storage hydroelectricity.[read more]

China's Coal Consumption Fell in 2014

January 28, 2015 by Lauri Myllyvirta

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]
