Welcome back to Part 2 of our interview with Scott Sullivan, my friend and one of the best networked executives in the industry. Earthquake excitement has diminished in the New Jersey area, but seismic changes in solar continue around the country. In Part 1 we discussed what happens in the solar and storage industry — really every industry — when company profits decline. It’s a tough adjustment to make, and many companies have not yet recovered from this high interest rate environment. Neverthel...

Seismic changes in the solar and storage industry? Who would have thought that our friends in New Jersey would relate so viscerally? Their recent 4.8 magnitude quake in early April literally extended this metaphor across the country. Metaphors aside, the solar and storage industry is changing faster now than I have ever seen: * Electric rates are soaring, along with utility profits * Solar equipment costs — panels, inverters, batteries — are declining * UL-3741 standards for rapid shutdown throw...

March isn't just about shamrocks and leprechauns; it's also Women's History Month, highlighting the incredible contributions of women in various fields. But have you ever wondered about their role in the energy transition? In general, women are just as involved as men — not just in solar, but also in batteries, hydrogen, policy-making, electrification, and manufacturing. However, there's a glaring gap in representation when it comes to the construction side of energy systems. But not at Luminalt...

The Learning Curve for understanding home batteries and solar systems is steep. Your battery system education will require mastering at least twice as much jargon, TLAs (that’s Three Letter Acronyms), specifications and industry gossip than ordinary solar systems. So if you don’t want to get bamboozled by an aggressive salesperson, this week’s podcast is a great place to start. Some of the topics and questions include: * What is the best way for me to expand my existing solar system? * What are ...

The Utility Empire is striking back. As a result, the rooftop solar industry is experiencing its first decline in growth ever. In California alone the end of Net Metering has resulted in an 80% drop in rooftop installations and 17,000 job losses among passionate Rebel solar installers. Utilities in other states are following California’s lead, leveraging their Death Star-caliber monopoly powers and millions in lobbying money to further reduce competition. Even though we need rooftop solar more t...

This week we’re talking about World Domination. Domination of energy production, that is. In the re-scrambled words of the wise and infamous Dr. Evil: “Why make Gigawatts when we can make…Terrawatts!” Indeed, solar is on track to completely dominate electricity generation. Solar is growing faster than wind, nuclear and LNG ever did. Alternatives to solar such as nuclear fission, nuclear fusion, CO2 capture and sequestration (CCS), and CO2 direct air capture (DAC) are way too expensive and very s...

If you’re thinking about solar there’s something important you should know. It should be obvious, but just in case: there is no such thing as Free Solar. Getting solar — or a battery -- installed on your house is not cheap and certainly not free. These projects are significant construction and electrical improvements. No company will install solar or a battery for free. I guarantee it. The Romans had a term for it: Caveat Emptor. Let The Buyer Beware. Unfortunately, disreputable companies still ...

It’s no surprise that this is the most common question, since the solar panels themselves are the biggest cost component of a typical rooftop system. But I’m not going to give you the single "Best Panel" answer you may be looking for. Sorry. With over 100 companies making solar panels worldwide — and vast differences in efficiency, aesthetics and reliability — there is no one answer. So instead I’ll focus on the factors and characteristics to help you make the best decision for your particular c...

As in year’s past, we in California greet the New Year with yet another electric rate increase. It’s almost impossible to believe this time — but on January 1, 2024, PG&E raised electric rates by another 28.4% according to the San Jose Mercury News. Just follow the money. Since 2017, Utilities and the IBEW spent over $111 million on politicians and ballot measures to maintain their monopoly. So it should be no surprise that our government passed laws that make California’s peak rates the highest...

I’ve added electrification predictions for 2024 to my customary set of solar and storage predictions. Electrification incentives in the Inflation Reduction Act (IRA) are already starting to drive demand for heat pumps and electrical upgrades, just as tax credits accelerated the solar and EV markets in the past. So here I go again sticking my neck out with these ten home energy predictions for 2024: EVs will be equipped with integrated 240-volt generators for home backup and evening power Heat pu...

It’s not a matter of IF your hot water heater dies – but WHEN. According to the Department of Energy, the average lifespan of a hot water heater is 13 years. So if your hot water heater is over ten years old – or if you’re planning to electrify your home -- the time to PLAN for a Heat Pump Water Heater (HPWH) is NOW. Heat pump water heaters have become consumer favorites — and the bête noir of natural gas companies – because they have efficiencies in the range of 200-300%. Much more efficient th...

The goal to cap global warming to 1.5C is just a pipe dream. At the rate the earth is warming we’ll hit that threshold in 2026 or sooner. And since our consumption of fossil fuels continues to increase without any meaningful reductions of airborne CO2 concentrations, we are on pace to hit 3C by 2035. It doesn’t take a doctor to diagnose the illness: our planet is sick from global warming. Or to determine the cause of the illness: CO2 emissions. Or the cure: stop burning fossil fuels. But fossil ...

When you electrify your home – with a heat pump HVAC system, EV charger, induction cooktop or heat pump water heater – your demand for electricity will go up. Duh. Or as Tim Allen would say: “I need more power.” Incentives as part of the Inflation Reduction Act (IRA) help reduce the upfront costs of these electrification upgrades. But the only way to reduce the operating costs of these new electrical appliances is with more solar power on your roof. But upgrading an old solar system is not for t...

By 2035 all new cars in California will be electric. It’s an achievable goal based on lower operating costs and rapid price declines for new EVs. But the current per kwh costs of EV charging continue to increase -- and we continue to be woefully short of necessary EV charging infrastructure. I predict a massive backlash against expensive and inconvenient EV charging. Our EV deployment goals are likely to fail. Miserably. The reason is simple: our EV charging paradigm is based on utility profit m...

Inside Scoop About Heat Pump HVAC Systems If you can answer these three basic questions, then don’t bother listening to this podcast. The questions are tricky, so if you're the least bit uncertain I suggest you listen to this week's riveting Energy Show episode. How can a heat pump be 300% efficient? Are gas furnaces still the most popular new heating system? Can you get an $8,000 IRA rebate and $2,000 Federal Tax Credit for a heat pump installation in 2023? First, we’ll delve into the way a hea...

There is one thing for certain as you electrify your house. You’ll need more electricity. Duh! But getting more electricity from the street to your house is not easy. Bizarrely, it often takes longer to do these electrical upgrades than it does to install your new all electric appliances. When — not if -- your old gas hot water heater dies, you don’t want to wait months for a new 240 volt circuit for that new super-efficient electric heat pump water heater. Nor do you want to delay the installat...

The Inflation Reduction Act, or IRA, became law in August 2022. It's packed with incentives across the entire value chain, including domestic manufacturing, energy-efficient products, and clean saving energy. But these fantastic incentives do not yet match the realities of what you can get today for your electrification project. The table below shows the most significant IRA electrification incentives that are available to homeowners in 2023, as well as pending IRA incentives in 2024. Many utili...

Batteries were everywhere at September’s RE+ Conference in Vegas. I counted over 100 different battery company and system vendors. It was more of a battery and solar tracker show than a solar show — demonstrating the rapid evolution of these clean energy technologies. But out of a hundred batteries on the show floor, there are only half a dozen that I would recommend to homeowners. Home battery systems should provide reliable backup power during a blackout, and also generate utility bill savings...

Proving the solar skeptics wrong, the U.S. Energy Information Administration (EIA) now expects that utilities will add 54.5 Gigawatts of solar generation capacity in 2023. And this capacity does not include 6.4 Gw of residential installations and 1.7 Gw of commercial installations expected in 2023. SIDEBAR: a Gigawatt is a billion watts of power. In 1955 the eminent Dr. Emmett Brown stated that the only power source capable of generating 1.21 Gigawatts is a bolt of lightning. Obviously things ha...

HEADLINE: Higher Electric Rates and More Blackouts Unfortunately, this is the new normal for most of the U.S. In other words: SNAFU This situation will not change. It’s a little-known fact that utilities use our money to influence politicians to maintain their monopoly. To the tune of $18m in California just in 2022. Government regulators are supposed to ensure that utilities provide inexpensive, reliable and safe power. However, this poorly regulated capitalism is not working. Just look at your...

Our society is moving rapidly towards electrification. Building electrification is good for the climate, good for our health, and good for our economy. We’ll all be using more electricity — it’s inevitable. Luckily, using all this extra electricity for our heating and our cars is inexpensive when you get it from rooftop solar and storage. But utilities have a monopoly on electricity distribution. They’re rubbing their greedy hands together like Montgomery Burns, safe in the knowledge that as lon...

On this week’s show we’re talking about the first steps toward your home electrification project. What I call the Low Hanging Fruit. These are easy and cheap energy efficiency measures — most of which you can do yourself (DIY) or do not require any special contractors. Many people recommend starting with an energy audit of your home. However, unless you're working with a local energy auditor that knows your local conditions and incentives down to the city level, the standard energy audit recomme...

More heat pumps were sold in 2022 than gas furnaces. And that was before the Inflation Reduction Act (IRA) kicked in, which provides an $8,000 rebate for most heat pump installations — on top of a $2,000 federal tax credit and city/county incentives that can exceed $3,000. Heat pumps are cleaner, more efficient and less expensive than most conventional gas furnaces and air conditioners. But the variety in heat pump system configurations, efficiency, and costs is enough to make even a geeky engin...

How would you like to reduce your home energy costs, improve your health and comfort, and at the same time do your part to improve the environment? If your answer is “yes,” then listen to this week’s Energy Show episode. If your answer is “no,” then maybe you don’t need your share of the $10,000-$40,000 incentives that are available for your home. The concept of Home Electrification is simple: you replace gas appliances with electric appliances — either all at once, or as the old gas appliances ...
