Very quietly, California utilities are threatening to undermine the dream of widespread clean energy in our state. If this happens, the state will lose jobs, our booming solar industry will suffer a major setback and our progress at cutting emissions and displacing dirty energy will stop in its tracks.
At issue is a proposed ruling that the California Public Utilities Commission (CPUC) is slated to consider on May 24, which would increase the number of rooftop-solar installations that qualify for "net metering." Net metering is like the rollover credits on your cellphone. It enables utility customers with solar panels connected to the grid to receive full credit for all of the electricity they produce. Excess power generated during sunny daylight hours gets fed back to the grid, and the customers earn a credit that helps offset their electricity costs during the times when they're using more power than they are generating.
Net metering is fair, and it's a critical part of the equation for making rooftop solar installations affordable for thousands of homeowners and small businesses. Thanks in large part to net metering, California has one gigawatt of customer-owned clean energy (more than 100,000 rooftop solar systems). In addition, clean energy fed back onto the grid by net-metered systems makes it possible for California to turn off more "peaker" power plants—the state's dirtiest and least-efficient—which are typically powered by diesel or gas and sited near poor neighborhoods.
Most California consumers probably take it for granted that they should receive the full value of energy they generate and put back into the grid. Why would they choose to buy or lease rooftop solar panels if they will be forced to give away a significant percentage of the power they generate to the same utility that's sending them a bill every month?
But we can't take net metering for granted, because when California passed its net metering law in 1996, it included restrictions. Most alarmingly, under the current law, utilities can refuse to accept new net-metering customers altogether once the amount of power coming from those customers reaches five percent of "aggregate customer peak demand."
The utilities have chosen to interpret "aggregate customer peak demand" as meaning the highest overall system demand for energy in California history, which was on July 25, 2006 during a record heat wave that killed more than 100 people. Under that interpretation, California will reach its five percent net-metering cap at approximately 2.5 gigawatts—which could happen as soon as early next year. The CPUC has proposed that a more sensible way to calculate "aggregate customer peak demand" is to add up (aggregate) the peak demand of every individual utility customer. If you calculate it that way, California will reach its net-metering cap at approximately 4.6 gigawatts of capacity. To put that in context, Gov. Brown has said the state needs to reach 12 gigawatts of installed local clean energy sources such as rooftop solar panels, small wind turbines and fuel cells by 2020.
Clean, renewable, locally generated energy is not a luxury for California nor, for that matter, the rest of the world. Failing to use clean energy translates to continuing to use dirty, polluting fossil fuels that threaten our health, our economy and our climate. We cannot afford to stumble when we should be running as hard as we can to take full advantage of the energy that rains down on our rooftops day after day—most of it wasted as we burn more coal, frack for more natural gas and drill for more oil. California is a leader—not just in the U.S., but in the world. It would be shameful if utility companies in this forward-looking state succeeded in making it harder for their customers to harvest the clean solar energy of the future.
The customers who want to buy or lease solar systems wouldn't be the only ones affected, either. At a time when the residential construction industry is still struggling, the boom in solar-rooftop installations has created thousands of badly needed jobs, which would be put in jeopardy.
Utility companies can't have it both ways. They cannot boast about how much they love clean energy while simultaneously working to undermine it. If the utilities don't like net metering (which, clearly, they don't), then the proper response is to propose something better—not to sabotage the current system and derail the transition to clean, locally generated power.
‘Existential Threat to Our Survival’: See the 19 Australian Ecosystems Already Collapsing
By Dana M Bergstrom, Euan Ritchie, Lesley Hughes and Michael Depledge
In 1992, 1,700 scientists warned that human beings and the natural world were "on a collision course." Seventeen years later, scientists described planetary boundaries within which humans and other life could have a "safe space to operate." These are environmental thresholds, such as the amount of carbon dioxide in the atmosphere and changes in land use.
The Good and Bad News
<p><span>Ecosystems consist of living and non-living components, and their interactions. They work like a super-complex engine: when some components are removed or stop working, knock-on consequences can lead to system failure.</span></p><p>Our study is based on measured data and observations, not modeling or predictions for the future. Encouragingly, not all ecosystems we examined have collapsed across their entire range. We still have, for instance, some intact reefs on the Great Barrier Reef, especially in deeper waters.

"Today's interim report from the UNFCCC is a red alert for our planet," said UN Secretary General Antonio Guterres.
The report, released Friday, looks at the national climate efforts of 75 states that have already submitted their updated "nationally determined contributions," or NDCs. The countries included in the report are responsible for about 30% of the world's global greenhouse gas emissions.

Plastic Burning Makes It Harder for New Delhi Residents to See, Study Suggests
India's New Delhi has been called the "world air pollution capital" for its high concentrations of particulate matter that make it harder for its residents to breathe and see. But one thing has puzzled scientists, according to The Guardian. Why does New Delhi see more blinding smogs than other polluted Asian cities, such as Beijing?

In a historic move, the Delaware River Basin Commission (DRBC) voted Thursday to ban hydraulic fracking in the region. The ban was supported by all four basin states — New Jersey, Delaware, Pennsylvania and New York — putting a permanent end to hydraulic fracking for natural gas along the 13,539-square-mile basin, The Philadelphia Inquirer reported.
