Grid Passes Eclipse Test


Date: August 23, 2017 at 12:30 PM

This week, a total solar eclipse crossed the United States for the first time in nearly a century. The eclipse dimmed the sun for several hours, leaving utilities questioning the impact on solar power generation and whether grids are prepared to handle state policies mandating a greater renewable energy mix. As solar output plunged along the route of totality, grid operators and utilities were forced to manage the drop by bringing on greater amounts of natural gas and hydro. Those states with high solar producing capacity, such as California and North Carolina, were significantly impacted by the path of the… [more]

State Environmental Commitments Are Key to Nation’s Clean Energy Future

While it is clear that energy and the environment did not play a decisive role in the election, 2017 will nevertheless bring a new set of challenges for energy policy, and elevate the conversation to a higher level. At the federal level, the fight to stop climate change looks bleak. State Environmental Commitments and clear, deliberate leadership at the state and local levels will become essential to advance clean energy goals. Fortunately, New York’s history of advancing favorable environmental policies has resulted in valuable lessons that can be adapted and implemented in other states to increase economic development, create jobs,… [more]

What Will Energy Policy Look Like Under President Trump?

President-elect Donald Trump has only vaguely defined his plans for energy policy, via his website and campaign statements and tweets. As a result, one can only speculate what changes to expect from Trump energy policies. Nevertheless, a recent report by S&P Global Platts aimed to predict how electricity will be generated under Trump energy policies. The analysis assumed Trump would allow subsidies for renewable energy to continue their scheduled scale down through 2020, and enact no new policies to support wind or solar. This is consistent with recent reporting indicating that Trump does not plan to act against renewable energy… [more]

If a Tree Falls in the Forest…Should We Use It to Generate Electricity?

California is experiencing what has been dubbed the worst epidemic of tree mortality in the state’s modern history, with the death of an estimated 66 million trees since 2010. There seems to be widespread – but not unanimous – agreement that leaving close to 40 million dry tons of wood in the forest will increase wildfire risk to unacceptable levels. A tree-mortality task force is working to safely remove the dying trees by using the tree services where some of which can be harvested for timber. But given the current trajectory, lots of wood will be burned on-site. This begs… [more]

Intermittent Renewables Can’t Favorably Transform Grid Electricity

Many people are hoping for wind and solar PV to transform grid electricity in a favorable way. Is this really possible? Is it really feasible for intermittent renewables to generate a large share of grid electricity? The answer increasingly looks as if it is, “No, the costs are too great, and the return on investment would be way too low.” We are already encountering major grid problems, even with low penetrations of intermittent renewable electricity, which in the U.S. was 5.4% of 2015 electricity consumption. In fact, I have come to the rather astounding conclusion that even if wind turbines… [more]
