SD to hit net metering cap – higher elec rates for solar customers

solar

SDG&E will likely surpass its cap on the number of rooftop solar systems that can sell electricity back to the utility in just a matter of days — well before any other utility in the state.

“It’s an indication that more San Diegans are choosing to go solar so that they have a choice as far as what they pay for electricity as opposed to being beholden to a monopoly,” said Daniel Sullivan, CEO of Sullivan Solar Power.

But blowing past the cap also means that homeowners and others who want to use net metering — the billing mechanism in which utilities pay rooftop solar customers for the excess electricity their systems send back to the grid — are going to have to pay a little bit more.

Under rules set by the California Public Utilities Commission, once net metering at the state’s three investor-owned utilities exceeds 5 percent of peak customer demand, a “successor tariff” goes into effect for new customers.

As of Friday afternoon, San Diego Gas & Electric was just 8.2 megawatts shy of hitting its 5 percent cap. That translates into about 1,250 typical residential rooftop systems needed to reach SDG&E’s cap, according to state figures.

Once the cap is reached, those who want to use net metering will have to:

*pay a one-time interconnection fee that is estimated to cost between $75 and $150

*pay an estimated 2 cents to 3 cents per kilowatt hour for all of what is called “non-bypassable charges” for the electricity their buildings consume from the grid. The charges will help pay for low-income and efficiency programs, and

*go on a “time-of-use” rate instead of the flat rate paid by most residential consumers each month.

Data In – Reneables not stopped by cheap oil

data

The report looked at wind, solar and geothermal energy, as well as energy from biofuels, like sugarcane. It did not take nuclear energy or hydropower into account when calculating renewable energy capacity.

While the falling cost of solar and wind power drove the increase, renewables also got a bump from new investment by private companies and national governments, according to the report. Overall, investment in renewables hit $286 billion in 2015, up from $273 billion the previous year.

Wind and solar accounted for a majority of new renewable energy projects in 2015. The world’s solar capacity has been growing steadily for a decade, and last year saw the biggest leap in new solar capacity ever.

Machine turns your food waste into gas for cooking

biogas

HomeBiogas based in Beit Yanai, Israel, is a biogas system that turns food and organic waste into clean cooking gas, and its byproduct can be used as liquid plant fertilizer. Best part? It easy to assemble and can be placed in your own backyard.

You can place all kinds of organic waste including meat, dairy and even used kitty litter into the system. Once inside, bacteria inside the digester will decompose the organic material and release biogas.

This Machine Turns Your Food Waste Into Gas For Cooking

Homebiogas, which costs $995 for a limited time, runs without electricity and its daily gas output is equivalent to about 6 kilowatt-hours of energy.

“In layman terms, enough gas for three hours of cooking,” Ami Amir, marketing and business development for HomeBiogas, told Waste 360. “It accepts meat, fish, fats, oils and dairy stuff — all of which are not treatable by composters.”

Amir adds that the gas may be used for lighting or heating water by using devices that are compatible with low-pressure biogas.
