Boston Globe: Major Solar Incentive Runs Out in Mass.

Solar energy in Massachusetts faces an uncertain future as two state programs that helped fuel a boom insolarinstallations are on hold, awaiting action by state officials.

On Friday, a generous incentive for the industry quietly evaporated, as subsidies that have helped finance solar power projects reached the limit set by the state. Another program, which allows homeowners and businesses to sell excess solar power to utilities, hit its limit in a large part of the state last year, and the legislature has yet to lift the cap on the amount of power that utilities must buy from these sources at retail rates.

Now the question is: What’s next?

CNN: The 370-mph 'Bullet' Fueled by Batteries

Speed freaks have been flocking to Utah's Bonneville Salt Flats for more than a century.

From Malcolm Campbell's Bluebird -- the first car to break the 300 mph barrier in 1935 -- to the jet- and rocket-propelled speedsters of 1960s and 1970s, the famous bleached white speedway has hosted some of the most iconic cars ever built.

Now a new breed of racers are taking on the famous speedway.

The latest arrival on the salt flats is an electric car -- the Venturi Buckeye Bullet 3 (VBB-3).

Vox: The Supreme Court Just Put a Crucial Part of Obama's Climate Plan on Hold

The Supreme Court just put a kink in President Obama's climate change plans. How big a kink? Well, that remains to be seen.

In a surprise 5-4 decision on Tuesday evening, the conservative justices halted implementation of the EPA's Clean Power Plan -- a major regulation aimed at cutting carbon-dioxide emissions from U.S. power plants. The hold will last until legal challenges to the rule are resolved.

Climate Central: Obama Confident in Climate Plan Despite Court Setback

The Obama administration is expressing confidence in its most sweeping climate change policy, despite the Supreme Court’s decision on Tuesday to block its enforcement while a major legal challenge works its way through the courts.

The Clean Power Plan, which aims to cut power plant emissions by 32 percent by 2030 compared to 2005 levels, was a critical part of U.S. negotiations at the Paris climate talks in December. The agreement struck there was bolstered by America’s promise to carry out its pledge to cut overall U.S. greenhouse gas emissions by 26 percent by 2025.

Consumer Affairs: Feds Decree Self-Driving Cars Are, Well, Driving Themselves

So let's say you're tooling down the road in one of Google's self-driving cars. A motorcycle policeman pulls you over and says you blew through a stop sign. Who gets the ticket?

Google thinks it should, since it is Google's software that is in control of the car. And the National Highway Traffic Safety Administration agrees, in a letter to Google.

But if that makes it sound like self-driving cars are just about ready to come streaming onto the 405, think again. Tests in northern climes are finding that the autonomous vehicles are not much better than humans when it comes to dealing with snow and ice.
