Rising panel costs hit solar power as electric-rate hikes boost appeal

By Mark Harrington

In recent weeks and months, a U.S. Commerce Department investigation has short-circuited a key supply source of solar panels from Asia, and one major supplier to the United States, LG Electronics, has exited the market, citing increased costs. The Commerce Department probe, looking at whether Chinese solar panel producers circumvented U.S. tariffs by shipping products through four other Southeast Asian countries, has reduced availability across the U.S. and led commercial solar firms to delay big projects.


Washington, D.C., is ‘ideally poised for electrification,’ Sierra Club finds. The city’s gas utility disagrees.

By Robert Walton

Renewable natural gas and green hydrogen could be used to help the District of Columbia affordably reach its 2050 carbon neutrality goal while avoiding costly grid upgrades, Washington Gas told the D.C. Public Service Commission in comments filed Tuesday.


PJM releases road map for creating ‘grid of the future’ to handle coming renewables, storage wave

By Ethan Howland

Torrid heat, raging wildfires and prolonged drought are putting California residents at increased risk of power outages, officials said Friday, as extreme weather driven by climate change puts additional stress on the state’s already-taxed energy grid.


Major grid dilemma: Treat fossil fuels like renewables?

By Miranda Wilson

Now, clean energy advocates have their sights set on another issue they say may give coal, natural gas and nuclear generators a leg up with PJM Interconnection, a regional transmission organization that oversees the flow of power in 13 states and the District of Columbia.


The fight for a national clean energy transmission system emerges on three fronts

By Herman K. Trabish Photo: Don DeBold

After years of studies showing a national transmission system is the most cost-effective way to meet growing clean energy and carbon reduction mandates, there is still no nation-spanning solution.

The federal government has finished another environmental review of a proposed transmission line that will carry wind-generated electricity from rural New Mexico to big cities in the West and similar reviews are planned for two more projects that would span parts of Utah and Nevada, the U.S. Interior Department announced Thursday.


Heat Pump Heads Rejoice: Washington State Now Requires the More Efficient Systems

By Lauren Leffer Photo: Silas Stein , AP Images

Washington is now the first state in the country to mandate energy-efficient (and possibly fossil fuel-free) electric heat pumps, over traditional furnaces and water heaters. The rules apply in new commercial and multifamily residential buildings with four or more stories.


The US has more clean energy projects planned than the grid can handle

By Jeff St. John Photo: George Rose , Getty Images

The proposed wind, solar and battery projects seeking interconnection to U.S. transmission grids today are enough to bring the country to 80 percent carbon-free electricity by 2030. But based on historical trends, less than a quarter of those planned projects are likely to be built.


Renewables are growing — but a backlog of projects is holding up a greener grid
