100% Renewables Plan Has ‘Significant Shortcomings,’ Say Climate and Energy Experts

Cities are increasingly moving ahead of countries in setting carbon-reduction goals and initiatives, according to a new report from banking giant HSBC.

More than 2,500 cities have now listed climate-change pledges on the Non-State Actor Zone for Climate Action (NAZCA) portal launched as part of the 2014 Lima-Paris Action Agenda, HSBC notes.

“We think this is extremely important because NSAs [non-state actors] can move quicker in implementing climate change policies and measures,” reads the report.

Cities and other NSAs tend to be faster than countries at making decisions, and are more accountable to their local electorates. They may also

Another week brings more moves and shifts at the upper levels of the energy industry.

The Edison Electric Institute (EEI), the national association of investor-owned electric companies, promoted Philip Moeller to executive VP of business operations group and regulatory affairs. Prior to EEI, Moeller served two terms as a commissioner with the Federal Energy Regulatory Commission.

(David Owens stepped down from the position this month. Listen to Stephen Lacey's lengthy podcast interview with Owens about his career and the range of issues that EEI is grappling with.)

It's a common claim from advocates: We know we can create a 100 percent renewable grid, because Stanford Professor Mark Jacobson said we can.

Jacobson's peer reviewed studies assert that it is possible to convert all energy use in the U.S., to wind, water and solar -- while maintaining grid reliability, saving money and creating jobs.

It will require a World War II-style mobilization, he notes. But it's possible.

That conclusion is being questioned in a big way.

On Monday, a battalion of fellow energy researchers published a rebuttal to Jacobson's plan in the same prestigious journal where his study

California’s Wholesale Distributed Solar Program Is in Trouble. Will Regulators Finally Fix It?

It looked like renewable energy advocates in Nevada were going to win the legislative Triple Crown last week, but two of the three clean energy bills in contention never made it across the finish line. 

Republican Governor Brian Sandoval vetoed the two bills on Friday, citing uncertainty amid Nevada’s pending shift to an open and competitive energy market. 

AB 206 would have increased the state’s renewable portfolio standard (RPS) to 40 percent by 2030, up from 25 percent in 2025, and created attractive new incentives for energy storage. The second bill, SB 392, would have established a 200-megawatt community solar program by 2023.

In the weeks after Energy Secretary Rick Perry kicked off a 60-day study examining the impact of wind and solar on fossil baseload power plants -- hinting that he might use DOE authority to halt state renewable energy targets -- an army of researchers, grid experts and renewable energy professionals showed up at his doorstep.

They were armed with a deep body of research (including a report from a prominent anti-subsidy libertarian think tank) and real-world experience (including from Perry's home state of Texas) showing that variable renewables aren't the threat to grid reliability that the Energy Secretary implies.

California’s Wholesale Distributed Solar Program Is in Trouble. Will Regulators Finally Fix It?

Huawei is obsessed with failure.

Or, to put it more precisely, the Chinese string inverter manufacturer is focused on pinpointing any possible source of failure in its products that need to endure at least 25 years in some of the world’s harshest conditions. It uses that information to ensure that its inverters achieve industry-leading reliability.

Not far from its corporate headquarters in Shenzhen, China, Huawei has a sprawling Global Compliance & Testing Center. The GCTC can mimic, and even exceed, the harsh conditions Huawei’s string inverters may encounter when they are deployed in large-scale solar power plants.

Huawei is the largest inverter manufacturer in the

Offshore wind equipment is reaching record heights and unforeseen low costs that are allowing it to be deployed with fewer and fewer subsidies.

MAKE Consulting (which recently joined the GTM and Wood Mackenzie family) has a new analyst note that further illustrates the increasing competitiveness of offshore wind.

Here are a few recent, relevant data points.

  • Denmark's Dong Energy, a leading offshore wind player, won two large wind tenders in the German North Sea unaided by any direct subsidies. (Although German ratepayers are footing the bill for interconnection to the grid, not an insubstantial cost, and that does amount to a subsidy.)
