PG&E, our local utility in Silicon Valley, caused a number of wildfires — including the recent Camp fire that destroyed the town of Paradise, killed 86 people and destroyed over 13,000 homes.The primary reason for this and other similar fires is that PG&E skimped on power line maintenance while enjoying record profits. Now they are bankrupt (again), and are scrambling to deal with the upcoming wild fire season.
Public Safety Power Shutoffs may happen far from fire danger areas. And these shutoffs could last for 48 hours or longer. So anyone relying on electricity for the necessities of life must prepare for an extended outage. Unfortunately, their recommendations ignore the cleanest, cheapest and safest backup power solution – solar and battery storage. Instead, PG&E recommends gas generators and stockpiling several days of fuel. Dumb idea to store all this extra fuel in fire-prone areas. Not to mention the challenges of connecting, starting and operating a gas generator safely.
Here is the letter that PG&E sent to my home:
Given the growing threat of extreme weather, we want all of our customers to be prepared for power outages. If elevated weather conditions, including potential fire risk, threaten a portion of the electric system serving your community, it will be necessary for us to turn off electricity in the interest of public safety. This is called a Public Safety Power Shutoff. We know how much our customers rely on electric service and want to work together to help you prepare for power outages.
A Public Safety Power Shutoff could impact any of our more than 5 million electric customers, including your home or business. Because elevated weather conditions can last several hours or days, we suggest preparing for outages that could last longer than 48 hours. Electric backup generators can keep the lights on, help appliances stay running, preserve perishable foods, and power essential equipment and electronics during a power outage.
Generators can also pose safety hazards, so it is important to understand how to safely operate your generator before an emergency occurs. This means doing regular safety checks and being sure you have enough fuel to last a few days.
As you can see from their letter above, PG&E recommends a gas generator for backup power (remember, the “G” in their name stands for “GAS”). No mention at all about using a cleaner, cheaper, quieter and safer battery backup system. Simple reason: they don’t want you to install solar or batteries since that reduces their revenue and profits. And if you buy an automatic natural gas generator they’ll make even more money selling you natural gas.
So Listen up to this week’s Energy Show as we discuss your options for dealing with these Public Safety Power Shutoffs — as well as considerations for selecting the best battery backup system to protect you and your family during these outages.
Studies show that electrifying our transportation and building sectors are the fastest ways to reducing greenhouse gas emissions. These sectors combined generate nearly 70% of total greenhouse gases in many states, including California.
Our country is making excellent progress in the transportation sector as electric vehicles replace conventional gas vehicles – which generate zero emissions when powered by solar- and wind-generated electricity. Since trucks and buses are larger, it will take a few more years before electrification of these vehicles becomes commonplace. Nevertheless, since average vehicles are on the road for about 10 years, it is entirely feasible to completely electrify California’s vehicles in 10 to 20 years. Without national leadership, this transition will take longer in the rest of the country.
25%of green house gas (GHG) emissions come from the building sector – mostly heating, cooling and lighting. When many buildings were constructed they were heated by fossil fuels, most commonly natural gas for both space heating and water heating. With new heat pump technology it is actually cheaper to heat and cool a building with electricity – resulting in zero GHG emissions if this electricity is generated by solar or wind. Other GHG savings measures — such as LED lighting, better windows and insulation, electric ovens, induction cooktops, and better building controls – are also relatively straightforward to implement.
For new construction, it is easy to build these more efficient and cost effective solutions in. But just in the state of California it will take 50+ years for the approximately 12 million existing single family homes 3 million apartments and 700,000 commercial buildings to completely change over to these new technologies.
Unfortunately, we don’t have 50 years to make this transition – more like 10-20 years if we want to prevent global temperatures from rising more than 1.5 degrees C. On the surface, the key barrier to making this transition is the cost for new vehicles and the cost to retrofit existing buildings. New buildings are relatively easy since building electrification is actually cheaper than space and water heating with fossil fuels.
The real barrier to this transition in existing buildings is the stubborn and selfish attitude of incumbent fossil fuel industries. Architects, builders and contractors are happy to install appliances powered by electricity instead of natural gas. But fossil fuel providers, including gas utilities, oppose these electrification efforts at every opportunity. Just consider the extra costs your utility adds to upgrading your electric service and removing your natural gas connection. Please Listen Up to this week’s Energy Show as we discuss solutions to removing these barriers to building electrification.
California was the first state to set aggressive goals to reduce greenhouse gas emissions. Senate bill 32, AKA Cap and Trade, will reduce greenhouse gas emissions 40% below 1990 levels by 2030. We are well on our way to meeting these goals, and happily a dozen other states are pursuing similar paths. In 2018 Governor Brown issued an executive order to go even further: achieving carbon neutrality by 2045 and negative greenhouse gas emissions afterwards. The Governor and Legislature have allocated more than $6 billion dollars — collected from the Cap and Trade Program — to fund the transition away from polluting fossil fuels.
Greenhouse gas emissions come from a variety of sources: 40.6% transportation, 25.8% industrial processes, 12.6% commercial (mostly buildings), 11.9% residential, and 9.2% from agricultural and forestry. As a result of previous policies, most significantly renewable portfolios standards, solar and wind — we have hit most of our goals in the electricity generating sector. Excellent progress is also being made in transportation, most notably with electric cars. California is also making progress in the commercial vehicle segment by incentivizing electric buses and trucks.
Nevertheless, almost 25% of our GHG emissions still come from buildings: natural gas for space heating, hot water heating, clothes washing and drying, cooking, and pool heating. New construction standards, both for commercial buildings and residences, will almost completely eliminate natural gas in new buildings. However, natural gas appliances are embedded in our existing homes and commercial buildings, and many of these buildings will be with us for another hundred years (if they are not under water by then).
It’s a big job to change out the appliances in our current building infrastructure. To learn more about these challenges and realistic solutions, please Listen Up to This Week’s Energy Show as we speak with Jeff Byron. Jeff served as the Commissioner at the California Energy Commission for 5 years and more recently a member of the Cleantech Open and Band of Angels. Jeff actually walks the talk, and currently lives in a net zero carbon emission home.
California utility companies recently announced their Public Safety Power Shutoff programs across the state. Bloomberg News said “California May Go Dark This Summer and Most People Aren’t Ready.” California’s Governor Gavin Newsom was quoted as saying “I’m worried. We are all worried about it for the elderly. We are worried about it because we can see people’s power turned off for not just for a day or two but potentially for a week.”
These public safety power shutoff events are already happening around the state. Utilities turn off the power if there is the possibility of danger imposed by things such as high winds or wildfire, dry vegetation, low humidity, observations of dangerous conditions by field personnel and red flag warnings from the National Weather Service. The Paradise fire in 2018 was started when PG&E decided NOT to shut power off in a fire prone area. Now all utilities are erring on the side of caution, shutting off power when there may only be a remote chance of a fire – certainly better than burning down a town.
Unfortunately, looking back over the past fifty years, the reliability of our power grid is not getting better. The weather is getting hotter, there is more housing in forested areas, we need electricity more than ever, and some utilities have been skimping on maintenance to maximize their profits. Electricity has become the most important fuel for our society. So when the lights go out, our 21st century lifestyle reverts to the19th century.
To learn more about these Public Safety Power Shutoff programs, what the utility companies suggest (buy a gas generator!), plus better solutions (hint: solar with battery backup), Listen Up to this week’s Energy Show.
There is a new electricity provider serving customers in the city of San Jose: San Jose Clean Energy (SJCE). Technically they are not a utility since PG&E still provides distribution services: maintaining local wires and transformers, as well as providing billing. SJCE’s electricity is cleaner (almost all from renewables) and slightly cheaper.
Some people wonder why we need another utility or electricity provider. The reason is simple: investor owned utilities (IOUs) like PG&E charge more for electricity than municipally owned utilities. These new electricity providers, called Community Choice Aggregation (CCA) utilities, are managed by the cities and/or counties they serve, operate with low overheads, and buy power from inexpensive wind and solar farms.
The utility industry is going through a massive transformation. Old fashioned coal, nuclear and gas power plants are more expensive than wind and solar. In fact, business and residential customers can install solar on their rooftops for much less than it costs their local utility to delivery power. Prices for battery storage are dropping, making it cost effective for customers to install a battery system both for time-shifting energy use as well as backup power. As a result of these “behind the meter” electricity technologies, the economics of centrally generated power sold by an investor-owned utility no longer make sense in many locations.
In addition to San Jose Clean Energy, Northern California is already served by CCAs in Marin (Marin Clean Energy), San Mateo (Peninsula Clean Energy), Santa Clara County (Silicon Valley Clean Energy), with about a dozen more CCAs in operation or in formation. To learn more about CCAs and how they are taking off in communities across the U.S., listen up to this week’s Energy Show.
Barry Cinnamon has been blogging about the Solar Industry since 2007.
Barry hosts The Energy Show, a weekly 30 minute talk show that runs every Saturday at 1:30 PM on KDOW Radio AM in San Jose California.
Every week Barry provides practical money-saving tips on ways to reduce your home and business energy consumption.
Barry Cinnamon heads up Cinnamon Solar (a San Jose residential and commercial solar and energy storage contractor) and Spice Solar (suppliers of built-in solar racking technology). After 10,000+ installations at Akeena Solar and Westinghouse Solar, he’s developed a pretty good perspective on the real-world economics of rooftop solar — as well as the best products and services for homeowners, manufacturers and installers. His rooftop tinkering led to the development of integrated racking (released in 2007), AC solar modules (released in 2009), and Spice Solar (the fastest way to install rooftop solar modules).
