But the definition of circular economy remains unhelpfully broad.

When Amsterdam’s Schiphol Airport remodeled a terminal, it didn’t buy light bulbs; instead, the company signed a contract for “light as a service” from Signify, the company formerly known as Philips Lighting. Signify owns the physical lights, giving it the incentive to make products that last as long as possible and that can be easily repaired and recycled if anything breaks.

The service is one example of a shift to a circular economy model. Rather than just mining materials and manufacturing products that ultimately end up in landfills, companies are increasingly trying to figure out how to use resources in closed loops.

Lessons from the Lone Star State: A surge in wind power on the Texas grid didn’t cause reliability problems (and brought down electricity prices) because regulators improved the efficiency of wholesale electricity markets. Sarah Fields Photography/Shutterstock.com

U.S. Secretary of Energy Rick Perry in April requested a study to assess the effect of renewable energy policies on nuclear and coal-fired power plants.

Some energy analysts responded with confusion, as the subject has been extensively studied by grid operators and the Department of Energy’s own national labs. Others were more critical, saying the intent of the review is to favor the use of nuclear and coal over renewable sources.

So, are wind and solar killing coal and nuclear? Yes, but not by themselves and not for the reasons most people think. Are wind and solar killing grid reliability? No, not where the grid’s technology and regulations have been modernized. In those places, overall grid operation has improved, not worsened.

Beyond simply contracting for solar, utilities are increasingly investing in the sector to ‘position themselves to be the utility of the future'

Solar energy is becoming a generation resource so ubiquitous that utilities are looking beyond simply contracting for new capacity and are increasingly moving into the sector themselves.

Solar added a record-breaking 14,762 MW of capacity in 2016, nearly doubling its 2015 growth. The resource added 39% of all new U.S. generation capacity in the year, making it the leader among all resources for the first time.

Growth was dominated by utility investment in 2016, a trend that’s expected to continue, according to a new report from the Solar Energy Industries Association and GTM Research.

By almost any measure, the U.S. solar market is on fire.

Installations of solar panels are expected to soar by a third this year, the price of solar power is now cheap enough to compete neck and neck with gas and coal-fired power in places like California, and the fledgling industry received a vote of confidence last week when U.S. President Barack Obama announced a groundbreaking plan to curb power plant emissions. Even China's currency devaluation could cut panel costs for U.S. solar installers.

Wall Street, however, has been dumping solar shares this year, largely on concern, which investors say is misplaced, that tumbling oil prices will sap demand for alternative energy, even though oil isn't used to generate power.
