The Energy Show
Summary: The Energy Show, hosted by Barry Cinnamon, is a weekly 30 minute talk show that runs every Saturday 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 Energy Systems (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).

Copyright 2019 - The Energy Show, Barry Cinnamon Unless you have rooftop solar, you’re probably incredibly unhappy about rising electric bills. This misery is even worse for commercial customers since -- in addition to energy charges (billed on a kilowatt-hour basis) -- they also pay for peak demand charges (billed on the maximum kilowatt demand each month). For example, let’s say your business uses industrial equipment and a variety of office equipment. Your company uses 50,000 kwh of energy per month; at a rate of $0.15/kwh, your electric bill is $7,500 per month. In addition, your peak demand may be 300 kilowatts in a typical month; at a peak demand rate of $20 per kilowatt, you also pay $6,000 in demand charges every month. As a conscientious and generous employer, you decide to install 20 EV chargers in your parking lot so your employees can charge up their cars while at work. Each employee may charge up their car with about 10 kwh per day — or $1.50 worth of electricity each, or $600 for all employees each month. A nice employee perk, and not too expensive. However, since 20 employees plug in their cars at about the same time every morning, and each charger draws about 5kw, your extra electricity peak demand will be 100 kw, or an extra $2,000 per month. Ouch! So for many commercial customers, peak demand charges are a bigger cost than energy charges. Ordinary rooftop solar systems may not have a big impact on demand charges. However, batteries or special control systems in conjunction with rooftop solar can significantly reduce these demand charges. To learn how your company can reduce peak demand charges, listen to this week’s Energy Show as we speak with John Powers with Extensible Energy. Extensible Energy has software that helps commercial solar buildings to use electricity intelligently and reduce peak demand charges.
Copyright 2019 - The Energy Show, Barry Cinnamon 30% of the costs of a solar or battery storage system are paid for with the Solar Investment Tax credit. The Solar Investment Tax Credit (ITC) is the biggest renewable energy incentive in the country, and helps make solar affordable for just about every business or homeowner in the U.S. with a sunny rooftop. The solar ITC has been around for almost ten years – but 2019 is the last year that it is in full effect. The solar ITC steps down to 26% in 2020, 22% in 2021 and zero for residential systems in 2022. As in year’s past, there will be a big rush to get systems installed before the end of the year – and even a bigger rush at the end of this year since systems will effectively be 4% more expensive on January 1, 2020. Moreover, California’s public utilities have put their foot on the solar + battery storage accelerator with upcoming Public Safety Power Shutoff announcements. The 30% tax credit fully applies to battery storage systems used for backup power as long as the battery is charged by solar at least 75% of the time. Businesses and homeowners are realizing that a clean, renewable, and quiet solar + battery backup system is more reliable and cost effective than traditional built-in gas and diesel generating systems. The solar ITC is a straightforward credit (not deduction) on your business or personal tax return, and is not affected by the alternative minimum tax. Other incentives, such as business equipment depreciation, can also be combined with the solar ITC – in many cases cutting the total cost by 50% or more. To learn more about how your home or business can leverage the Solar Investment Tax Credit for both energy and backup power, tune in to this week’s Energy Show.

Copyright 2019 - The Energy Show, Barry Cinnamon 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.
Copyright 2019 - The Energy Show, Barry Cinnamon The United States is a representative democracy. Citizens vote for politicians who, theoretically, advocate for their needs: things like better healthcare, lower taxes, cleaner air, and new technologies such as solar. But one cannot check off the “solar” box on a voting ballot. Instead, we have to vote for elected officials whom we trust will work on solar policy on our behalf. Vote Solar was founded in 2002 by Adam Browning and David Hochschild to bring solar into the mainstream by helping to shape solar policy. Among the policy wins that Vote Solar has achieved includes incentives (tax credits and rebates), modernizing our electric grid, expanding access to solar and storage technologies across all economic sectors, and advocating for solar + storage friendly electric rates. Polls across the U.S. show that solar and renewable energy rate 90% and higher in the minds of voters . The challenge is turning that latent voting power into actual political power. Please Listen Up to this week’s Energy Show as Adam Browning, Vote Solar’s Executive Director, explains how their advocacy efforts have achieved so many solar wins to date — along with the hard work we all have ahead of us as we make solar a mainstream energy source throughout the U.S.

Copyright 2019 - The Energy Show, Barry Cinnamon 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.
Copyright 2019 - The Energy Show, Barry Cinnamon The 2020 presidential election has been in full swing for months, even though it’s still only 2019. Are things going faster as I get older, or are we in a constant stage of electioneering? Hmm, don’t answer that. With one notable exception, all of the presidential candidates have positions on climate change – AKA Global Warming. President Trump’s position is basically to deny climate change, mock renewable energy, pull out of the Paris climate accords (signed by every other country in the world except the U.S. … perhaps they know something that we do not), brag about the U.S.’s oil production, and futility try to resuscitate the coal industry. Sometimes I feel as if I’m watching the Twilight Zone on my parent’s Magnavox black and white TV. The Green New Deal has been proposed by a number of Democratic members of Congress. This plan is aspirational – the Green part is what we really need to address climate change, but the New Deal part is painfully lacking in specifics and realistic funding mechanisms. Jay Inslee’s “Evergreen Economy for America” is a well thought out plan that has a chance to meet our global warming targets. Joe Biden’s “Plan for a Clean Energy Revolution and Environmental Justice” is a little more political than practical, and may not provide enough funding fast enough. Listen Up to The Energy Show as we cover the politics of energy and the environment, ranging from the Trump administration’s environmental agenda (some would characterize this as oxymoronic), the Green New Deal, Jay Inslee’s Climate Plan, and what it will take for our next president to get us on the path of limiting global warming to 1.5 C.
Copyright 2019 - The Energy Show, Barry Cinnamon 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 the 19th 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.
Copyright 2019 - The Energy Show, Barry Cinnamon We’re talking about VAMPIRES on this week’s show — energy vampires. I know, it’s not Halloween yet, but these little energy suckers are insidious. I guarantee that you have dozens of little devices plugged into your home that are using a small amount of standby power, sucking energy all day and night. It really adds up, and causes nightmares for energy geeks like me. Research shows that these “plug loads” are about 1/3 of a home’s total energy consumption. We’re not talking about big appliances or lighting – but sneaky little things plugged in or wired in all around your home. Think about what you have. Obvious vampire loads are devices like computers, routers, Wi-Fi repeaters, phone chargers, TVs, cable boxes, cable modems, and entertainment consoles. Less obvious vampires are things like security systems, motion detectors, appliances (anything with a clock and an illuminated LED). The really sneaky devices that you might not see include doorbell and thermostat transformers, WiFi thermostats (Nest), hot water and furnace ignitors, garage door openers, irrigation systems, outdoor lighting control systems, cordless vacuum cleaners, and pool timers. To get a handle on this infestation, I went to every room with a Kill-A-Watt meter to measure the power consumption of each device. It added up to over 250 watts of 24×7 power — over $500 per year. To learn more about these energy vampires — how to identify them, calculate their costs, and stamp them out — tune in to this week’s Energy Show.
Copyright 2019 - The Energy Show, Barry Cinnamon To reduce greenhouse gas emissions we need to electrify all of our buildings. New electric appliances — such as heat pumps and induction stoves — are often less expensive to operate than conventional natural gas appliances. For example, at $2/therm for natural gas and $0.30/kwh for electricity, it costs about $1 to heat up a 65 gallon hot water tank for both gas and electricity. Add in rooftop solar and you can heat that tank for less than $0.25! So from both an economic and environmental standpoint it absolutely makes sense to replace old gas appliances with new electric appliances. Except for one big problem: many older homes have a 100 or 125 amp electrical service — which is insufficient to run most domestic hot water heat pumps, heat pump HVAC systems (heating and cooling), induction electric stoves and level 2 electric vehicle chargers. Not to mention anything other than a relatively small (< 5 kw) rooftop solar power system. The solution is to contact your electric utility to get an electric panel upgrade to a 200 amp system. Unfortunately, an electric panel upgrade is complicated. Every house is different — some homes have overhead wiring which is relatively easy to replace, and some homes are powered by underground wiring which can take many months and dollars to upgrade. Navigating the utility and city regulations for electric service upgrades can be a nightmare. To help us understand these issues — as well as the shortcuts and rebates that are available from some utilities — our guest on this week’s show is Sue Kateley. Sue is the former Executive Director of CALSEIA (now known as CALSSA), and has also worked as the Chief of Staff for California State Senator Bradford. Please listen up to this week’s Energy Show as Sue walks us through her personal experience with PG&E and her electrician as she cost-effectively completed an electric panel upgrade — and took advantage of some of the little-known incentives and procedures that can make this process much faster and cheaper.

Copyright 2019 - The Energy Show, Barry Cinnamon Every time I fly into a city I’m amazed at the number of naked, white, empty flat commercial rooftops that should be producing megawatts of power. Even in solar friendly cities such as San Jose there are only a few blue rooftops that one can see from the air. On this week’s Energy Show we’ll be talking about the tremendous opportunity for installing solar on flat roof commercial buildings. There are three reasons why commercial solar hasn’t grown as quickly as residential and utility solar. The first is customer economics: most commercial buildings are occupied by tenants who pay the electric bills, so the building owner does not have a compelling financial motivation to invest in solar to reduce the tenant’s operating costs. The second reason is that many building owners do not have the up-front capital for installing solar, nor do they have the long-term credit viability for a PPA or lease. The third reason is that, even with the ITC and low solar panel prices, the payback is still three to five years -- too long for businesses making shorter term investments. Fortunately, technology for installing solar on flat roof commercial buildings has continued to improve, reducing the mounting system and labor costs substantially. These new mounting systems are able to maintain the roof’s structural integrity, while at the same time addressing seismic and water intrusion issues. My special guest on this week’s Energy Show is Costa Nicalaou, CEO of PanelClaw. They have completed nearly 10,000 flat roof projects in 30 countries and over 2,000 permit offices. Please listen up as Costa explains PanelClaw’s newest products, and how they provide supporting engineering and permitting services to their network of commercial rooftop installers.
Copyright 2019 - The Energy Show, Barry Cinnamon Cities and states all over the country are making a big push to eliminate greenhouse gas emissions in both new and existing buildings. Not only are these changes a necessity to slow down global warming trends, but in many cases building energy costs are also dramatically reduced. Whole House Electrification (WHE), my latest favorite TLA (three letter acroynum) is accomplished by replacing all gas appliances (including your car) with cleaner and more efficient electric appliances such as heat pumps, EV chargers and electric induction stoves. LED lighting, better HVAC controls and upgraded insulation also help reduce building energy consumption. But starting a WHE project can be daunting -- even for an energy geek like me. Conventional wisdom recommends a home energy audit. When I did my energy audit using the DOE’s Home Energy Advisor program it recommended adding insulation to my stucco walls (almost impossible), sealing my ducts (they were really old), upgrading my old furnace and replacing my noisy air conditioner. None of these recommendations were really right for me. The reason is that traditional energy audits do not take into account the dizzying array of electric appliances, toys and embedded devices that power our 21st century lifestyle. Most of these energy audits are flat out wrong -- ignoring rooftop solar, battery storage, heat pumps and time-of-use electric rates. Combined, these new technologies provide significant savings for an electric home. Luckily, I found a kindred soul, Steve Schmidt, a pioneer in the new energy analysis industry. Steve founded Home Energy Analytics, which uses smart utility meter data to figure out what is really going on with energy in your house. Please Listen Up to this week’s Energy Show for Steve’s approach to prioritizing and then reducing energy costs, as well as his insights into Whole House Electrification.
Copyright 2019 - The Energy Show, Barry Cinnamon After your heating and cooling system, the next biggest energy hog in most homes is your swimming pool. I won’t feel bad if you skip this podcast if you don’t have a swimming pool — unless you’re an energy geek like me. My recent experiences addressing the energy problems in my old house really focused my attention on my swimming pool; in comparison, fixing my HVAC system was relatively easy (that’s the subject of another podcast). Here is a summary of my annual pool expenses: $1,300 for pool pump electricity ($0.45/kwh), $1,800 for pool maintenance, $500 for evaporative water loss (1.5 cents/gallon), $100 every time I want to heat up the pool in the spring/fall for the weekend ($1.75/therm), and $10 every time I want to heat up the spa. I’m too busy on weekends to do the pool maintenance myself, and the pool’s oval shape is not conducive to a pool cover. So I focused on reducing my pool’s electricity and gas consumption. It was surprisingly easy to cut my $1,300 electricity cost down to about $130 per year. First I installed a variable speed pump (about $1600) — if you have a pool, do this now. Second, since this pump is so quiet I run the pump at night during off-peak rates — currently $0.13/kwh. Third, with solar power on my roof my costs are down to about $65 per year ($0.07/kwh for solar electricity amortized over 25 years). Keeping the pool at a comfortable temperature is usually more problematic…except for our family since my wife and I don’t swim, and the kids generally don’t care how cold the water is. But if you want to keep your pool comfortably warm in the spring and fall, the best option is a solar pool heating system that uses black plastic collectors mounted on your roof through which pool water is pumped. Note that if you have this type of system you will need to run your pool pumps during the middle of the day — which may be during peak electric rate times. Another option is a pool heat pump. Air to water heat pumps are good in warm and humid climates (not always best in hot and dry climates). If you are more concerned about heating a spa, a water to water heat pump (cooling the pool and heating the spa) might make sense. For more about reducing your pool’s total operating costs so it’s no longer an energy hog, Listen up to this week’s Energy Show.
