How California Can Avoid Throwing Away Solar Energy

Why would anyone even consider shutting down as much as 80 percent of California’s giant solar power plants, which cost Read More →

California Has Too Much Solar Power — And That’s a Good Thing

No business wants to create a solution in search of a problem, particularly in the slow-changing energy industry. Instead, businesses want to find solutions for problems that exist and create ways to make money off their solutions. Enter the exigent problem California is facing: it has too much solar energy.

How California Blackouts Will Make Solar and Batteries A National Story

By Bill Roth, Triple Pundit

California again faces potential blackouts. This time it is tied to a natural gas storage facility called Aliso Canyon owned by Sempra Energy’s Southern California Gas. The site’s ability to deliver energy was crippled by a natural gas leak described as an ecological disaster comparable to the BP oil rig explosion. State officials worry that this key facility will not be able to deliver sufficient supplies to California’s natural gas generating plants during summer peak electricity demands. Read More →

The Perils of Wholesale Distributed Generation: Can California Live Up to Its Promise?

By Tam Hunt (Community Renewable Solutions LLC), Greentech Media

There has been a lot of excitement about the promise of wholesale distributed generation in California in recent years. But the state still hasn’t lived up to its promise. Wholesale distributed generation (DG) refers to front-of-meter systems (typically sized between 1 megawatt and 20 megawatts) that sell power directly to the utility or a third-party offtaker. This is an important market niche that remains underdeveloped. Read More →

Smug About Your Solar Roof? Not So Fast

By Severin Borenstein (Professor, UC Berkeley), The Los Angeles Times

If you’ve installed solar panels on your roof and feel aglow with environmental virtue, you may be in for a rude awakening. There’s a good chance someone else has purchased your halo and is wearing it right now. In most states (including California), rooftop solar panels earn Renewable Energy Certificates, which quantify how much clean electricity they produce. But if panels are leased or installed under a power purchase agreement, it’s the “third-party owner” — not the homeowner — who gets those certificates. Read More →

A Sunny Future for Utility-Scale Solar

By John Finnigan, The Energy Collective

Utility-scale solar and distributed solar both have an important role to play in reducing greenhouse emissions, and both have made great strides in the past year. Utility-scale solar is reaching “grid parity” (i.e., cost equivalency) with traditional generation in more areas across the country, and solar received a major boost when the federal tax incentive was recently extended through 2021.

Solar Power’s Pathway to Energy Supremacy

By Philip Wolfe, Renewable Energy World

In my previous article, I showed that there are no technological, resource or land area constraints that would prevent solar power from delivering any proportion of the world’s electricity needs, up to and including 100 percent. My follow up article illustrated how its viability is a function of the solar resource, declining capital costs, and their relation to traditional electricity prices. It showed why solar is already the low-cost option in places like Chile, and projected that this so-called ‘grid parity’ will progressively extended to other parts of the world. How fast that happens will depend in part on logistics, but primarily on regulatory issues; so this final article addresses in particular the politics of rolling out utility scale solar generation.

Energy Storage: Power Revolution

It is 2025 and another sweltering summer’s day in California. Millions of solar panels are soaking up the Sun’s rays to power the air-conditioning systems that keep homes and offices throughout the state cool. The devices are working efficiently thanks to an intelligent conversation taking place between the appliances and the electrical grid. As clouds drift across the Sun, casting shadows, the air conditioners deftly increase or decrease their output in sync with the varying flow of solar energy. In areas where the demand for electricity looks as though it will overload the power-transmission lines, home air-conditioning units take it in turns to go offline for an hour. In other areas, where solar power threatens to exceed demand, hot-water heaters are turned on to absorb the extra energy. Read More →

Building the 21st Century Power System

Imagine for a moment that you are a homeowner or a small-business owner and you just shelled out $25,000 or more for a shiny new rooftop solar generator. Then imagine your electric utility told you that you could not hook it up to the grid right away, not until your neighborhood circuit was upgraded. And even then, it said you could only turn it on during certain hours. I am guessing you would not be a happy customer. Read More →

California’s huge solar projects causing energy poverty

When ex-Gov. Arnold Schwarzenegger and former Interior Secretary Ken Salazar made their way onto a hot, dry alkali flat just west of the Interstate 15 freeway between Barstow and Las Vegas in late 2010, all anyone knew for sure was that they were opening an era of giantism in solar electricity in California. What no one could predict was that they were also putting a stamp of approval on the spread of energy poverty in many parts of this state. Read More →
