Nuclear Retirements Would Sabotage Clean Power Plan Carbon Reductions

September 1, 2015 by Jesse Jenkins

Nuclear power and the EPA Clean Power Plan

The EPA believes it’s new regulations will cut carbon emissions 32% by 2030. Reaching that goal depends on nuclear continuing to supply one-fifth of U.S. electricity. Retirements of existing reactors could sabotage the Clean Power Plan's emissions goals—and the EPA can't stop it. Here's why...[read more]

Technological Advancements Support Sustainability

July 9, 2015 by Dan Liggett

Sustainability and Tech

As the respected Worldwatch Institute cites in its 2015 global status report, released in June 2015, renewable energy continued to grow during 2014 against the backdrop of increasing global energy consumption, particularly in developing countries, and a dramatic decline on oil prices.[read more]

Levelized cost comparisons help explain value of various electric generation technologies

June 5, 2015 by U.S. EIA: Today in Energy

Power Generation and Cost

When power plants are built, several factors influence the choice of fuels and technologies that will ultimately generate electricity. Cost is one of the most difficult factors to compare, as technologies can have vastly different capital, fuel, maintenance, and financing costs, as well as different utilization rates.[read more]

Energy Source Comparison

You can’t get far in a discussion about the nation’s electric power sector without running into the question of costs. How do renewable sources, such as solar and wind, stack up against fossil fuels, such as coal and natural gas? How much will it cost utilities and ratepayers to build—and operate—a new power plant?[read more]

Europe Loses Billions in Badly Sited Renewable Power Plants

February 10, 2015 by Joseph Nyangon

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]

Hope For an Energy Rich, Sustainable Future

September 16, 2014 by Jim Baird

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]

Holland: Pioneering Sustainable District Heating Innovations

July 2, 2014 by Silvio Marcacci

Sustainable District Heating

District heating isn’t a new concept. Using heat from one resource to meet demand among a centralized group of consumers has long been in use, primarily through combined heat and power from natural gas. But communities are turning to sustainable sources for their heating demands.[read more]

I Almost Bought Hawaii's Electric Utility for $6B and Made It a Renewables Paradise

June 4, 2014 by Eric Wesoff

Renewables Paradise?

I have a confession to make. In 2011 I became involved, in a small way, in a multi-billion-dollar scheme to buy out HECO, Hawaii's electric utility, and take it private. The plan was to shift HECO from its reliance on fossil fuels and allow the island to be powered by its natural gifts of geothermal, solar and wind.[read more]
