Tesla announces prices for home battery

Power generation for both traditional electricity uses and transportation is changing.

Michael Liedtke and Jonathan Fahey wrote for AP and Inc. 1 May 2015, Elon Musk Unveils Tesla’s Ambitious New Home Battery System: “Our goal here is to fundamentally change the way the world uses energy,” Musk told reporters gathered in Hawthorne, California.

The batteries are likely to become more useful if, as expected, more utilities and regulators allow Continue reading

Fixing climate change is profitable

Batteries are just one of many reasons, including electric vehicles, smart grid, solar and wind power (including pass HB 57 and you can profit by getting financing for your own solar panels), plus massive savings on health care and electricity bills; batteries are one of many reasons that fixing climate change will save us all money, clean up our air and water, expand our forests, preserve property rights, and make some people rich:

In fact, a recent report suggests that revenue from the distributed energy storage market — meaning battery packs and other storage devices located directly at homes and businesses (many of which now generate electricity through solar) — could exceed $16.5 billion by 2024. Another report predicts $68 billion in revenue in the same time frame from the grid-scale storage market. This includes large-scale battery packs, hydro-storage systems that use cheap abundant electricity to pump water uphill to drive turbines later on, or even solar thermal systems that store energy as heat in molten salt.

And it’s all happening fast, so fast your jaw will drop if you’re not paying attention. So let’s stop talking about the costs of fixing climate change. It’s not just no-cost and free, not just in the future but right now; we’re all actually going to be better off through fixing climate change: healthier and more prosperous.

Solar boom charts

When a power source grows 66% a year on average people start taking notice. Few had heard of the Internet in 1993: now it’s in your pocket. In less than a decade, by 2023, solar power will generate more energy than any other U.S. source. To keep Georgia from being left behind, this is the year to change a 1973 law.

If charts like this one aren’t familiar yet, they will be in the next year or two:

Tim McDonnell, Mother Jones, 7 November 2014, Here Comes the Sun: America’s Solar Boom, in Charts: It’s been a bit player, but solar power is about to shine.

At 66% more per year, solar power’s current 1% of U.S. electricity next year will be 1.66%, then 2.76%, then Continue reading

Slight changes at Southern Company @ SO 2014-05-28

Solar car charging station at the Southern Company Stockholder Meeting: that’s new. Other solar changes were detectable, if you knew what to look for, and with hints from SO CEO Tom Fanning and new R&D VP Larry Monroe here are some, while we’re waiting on SO for video and transcript.

Two demonstration solar charging cars were on the lawn outside the breakfast tent: Continue reading

Last day to oppose NRC bad nuclear waste plan

Today you can object to the Nuclear Regulatory Commission’s (NRC) inadequate plan for radioactive waste storage.

Comment through regulations.gov on Docket #NRC-2012-0246-0456; here’s a link to the comment form.

NRC’s web page on Waste Confidence:

The public comment period on the Waste Confidence Draft Generic Environmental Impact Statement and proposed rule ends on Friday, December 20, 2013.

Background from Beyond Nuclear:

No safe, permanent solution has yet been found anywhere in the world—and may never be found—for the nuclear waste problem. In the U.S., the only identified and flawed high-level radioactive waste deep repository site at Yucca Mountain, Nevada has been canceled. Beyond Nuclear advocates for an end to the production of nuclear waste and for securing the existing reactor waste in hardened on-site storage.

Facebook event with more information.

Here’s a petition:

The NRC, by court order, has been required to gather public input regarding a Generic Environmental Impact Statement (GEIS) regarding the storage of nuclear waste that is grossly inadequate and leaves over 150 million Americans who live within 50 miles of a nuclear power plant at risk.

The NRC has declared that it would only be a SMALL risk to the environment and communities near nuclear power plants to store nuclear waste on-site for 60 years, 160 years or even INDEFINITELY if no permanent repository is established….

And NRC’s oversight committee is the Subcommittee on Energy and Power of the Energy and Commerce Committee, which just held a hearing 12 December 2013 on Oversight of NRC Management and the Need for Legislative Reform.


Which first to get more solar: fight big money or new technology?

In Georgia we’re still below 1% electric power generation from solar, and we can get to 20-30% with no new technology whatever. Georgia Power’s nuke overruns are already causing a reaction of still more distributed solar. Yet even that good news gets the usual reaction: “This is necessary but not sufficient: a breakthrough in energy storage technology is required.” Which just ain’t so; distributed rooftop solar alone is plenty to move Georgia way ahead. That’s why Edison Electric Institute calls distributed solar a massively disruptive influence on the utilities’ century-old cozy baseload model. What’s holding solar back is those same big utilities, who understandably don’t want to change their long-time cash cow. But they’re going to change, and pretty quickly.

People unfamiliar with the sunny south (which is most of the world south of, oh, Germany), still say things like this: Continue reading

Wind produces much energy

According to Herald Scotland 2 May 2011, Row after wind farms ‘turned off’:
Six wind farms were given six-figure payments to switch off their turbines because the Scottish grid network could not absorb all the energy being produced, it has emerged.

Research by the Renewable Energy Foundation (REF) found energy companies were paid a total of £900,000 for stopping the turbines for several hours between April 5 and 6 this year.

The REF said some of the payments were as high as 20 times the value of the electricity which would have been generated if the turbines kept running.

The National Grid makes constraint payments to power stations that agree to stop generating in order to stabilise the network.

It happens when the grid system or a section of the system is unable to absorb all the electricity being generated, and some generators that are contracted to generate are asked to stand down.

Sounds like they just need to fix their prices. Adding some local storage of some kind would also help.
