Whole House Electrification with Howard Wenger

Whole House Electrification with Howard Wenger

To slow the global warming trend, a number of states have committed to the aspirational goal of 100% carbon-free energy. As a species that literally evolved from burning wood and hydrocarbons, how can we possibly run our modern lives and economy without fossil fuels?

We can indeed achieve this transition quickly and economically. First, by converting all power generation to renewable, non-carbon sources. And second, by converting all fossil-fuel burning vehicles and appliances to electricity. Steady progress towards these conversions is being made. For example, 32% of California’s retail power came from renewable energy in 2018. The state is well on the way to converting to 100% renewable electricity. Use of EVs is growing steadily, and new building codes mandate the use of rooftop solar and electric appliances instead of natural gas.

The challenge is with the existing stock of residential and commercial buildings. Homes and businesses predominantly use natural gas for space heating, hot water heating and cooking. That’s where the concept of Whole House Electrification come in. Whole House Electrification is conceptually simple: replace gas appliances with electric appliances. In reality, one needs an energy audit to prioritize these conversions, then hire five different specialty contractors to do the work: insulation, solar, HVAC, plumbing, electrical and pool. It can be a daunting task.

Fortunately there are some pioneers out there – one of whom is my friend Howard Wenger. Howard was also a pioneer in the solar industry, with stints at AstroPower, PowerLight and SunPower. Please listen up to this week’s Energy Show as Howard discusses his experiences as he converted his house to 100% electricity, supplied — naturally — by solar.

Legal Issues for PG&E’s Bankruptcy with Angela Liponovich of Estriatus Law

Legal Issues for PG&E’s Bankruptcy with Angela Liponovich of Estriatus Law

PG&E’s bankruptcy will have a dramatic effect on all electricity users in northern California — as well as utility investors, California taxpayers, and the solar industry in general. Moreover, the bankruptcy of one of the largest utilities in the country is a harbinger of the need to change the traditional utility business model. Not only are utilities experiencing competition from businesses and homeowners installing their own solar and storage systems (for less money), but utilities are also experiencing much greater than expected costs related to maintaining their transmission and distribution services. Devastating fires are more common, people are living in more fire-prone areas, our need for electricity is increasing … and this situation is likely to get worse. (more…)

Is There a MicroGrid in Your Future

Is There a MicroGrid in Your Future


You know what they say: “Video killed the radio star.” Well I’m going out on a limb and adding video to this week’s podcast. But since my fans say I have a perfect face for radio, I’m not worried that this video podcast will affect my Arbitron ratings. Nevertheless, my guests on this video podcast are much more telegenic, so I encourage you to click through to this video link. (more…)

Avoiding a Global Warming Disaster

Avoiding a Global Warming Disaster

The bad news about global warming continues unabated. This fall the United Nations Intergovernmental Panel on Climate Change (fondly referred to as the IPCC) sent up an emergency flare. According to Amjad Abdulla an IPCC board member and chief negotiator for the Alliance of Small Island States, “The report shows that we only have the slimmest of opportunities remaining to avoid unthinkable damage to the climate system that supports life, as we know it.“ Obviously, small island states are at the most immediate risk. But if the earth’s warming trend continues, many populated areas around the globe will essentially be uninhabitable. (more…)

Fuel Cells Are Making a Comeback

Fuel Cells Are Making a Comeback


Energy storage is critical to our ability to eliminate the use of fossil fuels. Basically, we need a way to store the abundance of daytime solar and use this energy at night. Although lithium ion batteries have been getting most of the attention, fuel cells provide another way to convert fuels into electricity. (more…)

Climate Change – Time to Start Panicking

Climate Change – Time to Start Panicking


These days you can’t watch TV, read a news story or listen to the radio without seeing catastrophic fires, hurricanes, and high temperatures. The world is getting hotter. To illustrate, Death Valley recorded the hottest month ever recorded on Earth. Temperatures averaged 108.1 degrees day and night, all of July 2018. That beat last year’s record monthly temperature. This is not just a U.S. only story, it’s a worldwide issue. During the month of July 2018 record high temperatures were set on every single continent in the northern hemisphere (it was winter in the southern hemisphere). (more…)
