Pillars of Sustainability: How Cell Towers Can Transform the Energy Landscape, and Help Us Meet Global Energy Goals

Posted by Oscar Serpell

According to the World Bank, 100% of registered homes in the United States have access to the electricity grid, so it is unusual for a cell tower to be “off-grid,” and thus require a distributed source of energy in order to operate. However, in many parts of the world, mobile service has outstripped existing...


It’s Time for a Market-Oriented Approach to Clean Energy Investment in Pennsylvania

Posted by John Quigley

Pennsylvania has $9 billion worth of economically-justifiable distributed clean energy and energy efficiency projects waiting to be developed. Yet, there is little private sector activity in these markets beyond the minimum needed to meet modest state requirements for alternative energy and energy efficiency....


Details Matter on Energy Storage Policy in PJM

Posted by Thomas Lee

Will the growing share of renewables – which have created jobs and cut emissions –  threaten power grid stability? Intermittent renewable sources, such as wind and solar, are both variable (i.e. outputs vary across hours and seasons) and uncertain (i.e. you cannot perfectly predict this variation). As the public...


Side Effects Include... A Rare Opportunity for Pennsylvania

Posted by John Quigley

We’ve all seen the ubiquitous drug commercials on television that peddle the latest pill but list seemingly endless “common side effects” of taking it.  You wonder if the cure might be worse than the disease.

At least 12 states, and more than 200 U.S. cities have made a commitment to continue in the Paris Climate Agreement, and various...


Solar Supporters, Be Aware…Changes Coming?

Posted by Christina Simeone

Solar power is booming. But, supporters of solar energy need to be aware of at least two pending events threatening America’s short-term solar energy future. First, the potential for increased solar costs if new tariffs are placed on imported solar equipment. Second, how solar-heavy states like California manage...


As the U.S. Falters on Paris Agreement, Ethiopia Sees Opportunity in Renewables

Posted by Oscar Serpell

Donald Trump’s June 1st decision to withdraw the United States from the Paris Climate agreement was widely denounced by world leaders, scientists, and advocates around the world as ill-informed. Many believe the decision will significantly jeopardize our ability to succeed in this global effort to limit the planetary...


If It Sounds Too Good to be True, It Probably Is

Posted by John Quigley

If it sounds too good to be true, it probably is. I quoted that old saying three years ago in raising come cautionary flags about a provocative claim that the United States, and each of its member states, could get all of their energy from renewables by 2055. That proposition has since gained a life of its own.  It...


How Exxon Thinks About Climate Change

Posted by Mollie Simon

Although a carbon tax may seem like an impossibility given our current political climate, private companies have long been preparing to put a price on carbon. Wanting to plan for something that they see as a future inevitability, big oil companies have been building in carbon pricing to their financial models for...


Knowing the Unknowable: Benefits and Drawbacks to Agent-Based and Equation-Based Modeling

Posted by Oscar Serpell

Edward Lorenz’s famous hypothetical scenario of a butterfly flapping its wings and somehow, weeks later, causing a tornado hundreds of miles away, illustrates the chaotic and uncertain future outcomes of seemingly inconsequential behaviors taken today. This complexity, and the resulting uncertainty of predicting the...
