David Hochschild — California and the Dawn of the Clean Energy Era


David Hochschild

On Wednesday, October 24, David Hochschild, a commissioner on the California Energy Commission, delivered some hopeful news about the progress California is making to reduce climate pollution. His talk, sponsored by Acterra, took place at the Foster Art and Wilderness Foundation in Palo Alto and was titled, “Sunrise from the West—California and the Dawn of the Clean Energy Era.”

Hochschild was appointed by Governor Jerry Brown to the California Energy Commission in February 2013 in the environmental position. A longtime solar energy advocate, he worked with San Francisco Mayor Willie Brown to put solar panels on public buildings, and cofounded the Vote Solar Initiative, an organization advocating for local, state, and federal solar policies. He served as executive director of a national consortium of leading solar manufacturers and worked for five years at Solaria, a solar company in Silicon Valley.

Hochschild’s goal now is to “bring light in dark times,” when the national government is going in the opposite direction from what we need for clean energy development. He believes that California can show the rest of the country—and the world—how it’s done.

First, he showed how predictions of the growth of solar and wind were way too low. While the line on the graph for the prediction of solar implementation barely moves up, the actual installed solar generating capacity jets up at a steep angle.

On a different graph, going down in exactly the opposite direction, is the line representing the value of the top four coal companies. They have lost 99 percent of their value in recent years.

“It’s the beginning of the end of an era,” said Hochschild.

Hochschild disparaged the long history of subsidies to the oil industry—which are still going strong with no end date. Meanwhile, the much smaller subsidies for solar have short time spans.

“This causes a tilted playing field,” said Hochschild. “We’re wasting money propping up the oil industry.”

California’s economy has grown, as has its population, but the state’s emissions have gone down, except in one area—transportation. But with the passage of SB 100 with Governor Brown’s signature in September, the state is on track to reach 100 percent clean energy by 2045.

Hochschild explained that the 100 percent number represents “clean” energy, which is still being defined, but would not include nuclear. To get there, we will need to have diversity in the portfolio, including wind, solar, hydroelectric, geothermal, and others.

“For years, skeptics have said that moving to clean sources of energy would ruin the economy, drive up unemployment, and raise energy rates, but it hasn’t,” he said.

California actually leads the rest of the U.S. in renewables installed but has had 46 percent economic growth while over the same period the U.S. has seen 35 percent.

“Because we set energy standards, we use half the energy that the U.S. uses,” said Hochschild. “These old arguments are just wrong.”

Hochschild said that as a large market, California can affect manufacturers’ decisions on what to build. For example, our standards on the energy efficiency of TV sets saves consumers $1 billion a year, but the effect is magnified because companies choose to incorporate those standards into their products for everyone.

Three light bulbs

One easy way to save energy is to switch to LED light bulbs from traditional incandescents, which are being phased out. Starting on January 1, 2018, stores in California were permitted to sell the incandescent bulbs they had in stock but couldn’t order more. As it is, customers are embracing LED bulbs, which cost a little more (prices have been dropping) but last 20 to 25 years and use 80 percent less energy than incandescent bulbs.

Newer LED bulbs are available in a soft white and other shades, so they feel more familiar, emitting a warm glow. The compact fluorescent bulbs, which tended to have a harsh light quality, have faded away now that LEDs have taken over.

Topaz Solar Farm

Hochschild displayed images of large solar farms in the California desert that are producing vast amounts of electricity. The technology is improving so fast, he said, that they were able to incorporate improvements into the panels and the installation process mid-project.

The major computer and software companies, such as Google and Facebook, are all signing on for 100 percent renewable energy. Hochschild showed an aerial view of Apple’s massive donut-shaped campus, covered with 17 MW of solar panels.

The list goes on. California has the world’s second-largest lithium-ion battery plant (behind Tesla’s giant Gigafactory in Nevada). California leads the nation in energy from biomass, too.

Block Island

Block Island Offshore Wind Farm in Rhode Island

Offshore wind farms are developing—we saw the Block Island offshore wind farm in Rhode Island – the first one in the U.S. Offshore farms are easier to construct in the East, Hochschild explained, because the Atlantic shoreline is shallow, while the Pacific’s drops off. However, there is a new way of creating offshore wind energy in the Pacific Ocean by installing floating platforms for the windmills, tethered down to the sea floor. There are some significant benefits.

“Offshore wind installations out at sea are not only invisible from land, but more important–the wind blows more of the time out there—60 percent versus 35 percent on land,” said Hochschild. “And because it blows at different times of the day from the times when the sun is shining, it can offset times when solar panels aren’t generating electricity,” he added.

Offshore windmills are more expensive to install, but with greater capacity, they catch up by generating more energy.

Regarding employment, there are 86,400 solar workers in California. That’s more than the workers in every other energy industry. And, it’s growing, as solar installations are increasing, reaching about a million in California.

Hochschild believes that the best plan for clean energy would be to electrify all services and run them off a clean grid as we reduce use of natural gas. He talked about how much natural gas is used in homes today for furnaces, stoves, water heaters, and some dryers. But some new homes are being built without gas lines at all.

“It saves $3,000 right away by not having to run the gas pipes,” he said.

The good news continued. One hundred percent renewable energy will power the state’s high-speed rail system, when it’s built. California institutions have taken $6 trillion out of investments in fossil fuels.

Hochschild compared the fossil fuel industry methods now to the tobacco industry in the 1950’s. Service personnel during World War II were given cigarettes as part of their rations, building lifelong habits. Advertisements showed celebrities like Marilyn Monroe smoking, and even a doctor. Hosts smoked on TV. About half of the population were cigarette customers then.

“The industry was selling cigarettes and also doubt about the health risks,” he said, comparing it to the way fossil fuels are denying climate change today. “But with rigorous campaigns and limitations, such as placing warnings on the packs, removing cigarette ads from TV, raising the age to buy cigarettes, and increasing taxes, smoking is at about 15 percent now, and is heading down. We need to do the same thing with the fossil fuels industry.”

Electric vehicles are part of California’s plan to reduce CO2, and the state adopted the Zero Emission Vehicle Action Program in 2013. In January, Governor Brown signed Executive Order B-48-18, which sets goals of building 200 hydrogen fueling stations and 250,000 electric vehicle charging stations for 1.5 million EVs by 2025. The goal is 5 million EVs a year by 2030, which means that 40 percent of new vehicles would have to be EVs by then.

Per the ZEV Action Program’s website, in 2017, 5 percent of vehicles sold in California were EVs. There are now about 474,000 EVs in California, so there’s a long way to go to meet the goals, but sales are increasing, and Hochschild thinks it will accelerate.

“100 percent clean energy is solvable—but it’s not a silver bullet—it’s silver buckshot,” Hochschild said. “It is a combined effort of developing clean energy sources, increasing battery storage, lowering demand, and creating a regional grid,” he added. He also said that it’s likely that the first 80 percent of the way will be easier, while the last 20 percent could be more challenging.

So, although things look dire, California is leading the way, and will be doing a lot more in the future.

My Chevrolet Bolt EV at a Year and a Half

Bolt 7-8-18

Today marks the exact halfway point of my three-year lease on my 2017 Chevrolet Bolt EV, and the report is positive. I’ve accumulated 13,920 miles and have seen consistent range of 200-plus miles through the whole 18 months. Most of the time it’s between 220 to 230 miles, even with the heat/AC turned on. Other than a couple of minor glitches in the entertainment system, which haven’t reappeared appeared lately, the car has been trouble- and service-free. It has never gone back to the dealer, although I’m supposed to get the tires rotated.

What’s also been completely consistent is the silent, smooth trips I’ve taken, and the ability of the car to accommodate whatever I want to carry. That means an upright bass, two bass guitars, an amplifier, and multiple stands and cords for gigs with Fault Line Blues Band. I do not frequent places like the Home Depot or Costco, but if I did I’m sure I’d have no problem carting home loads of whatever I bought.

I did run into a situation a couple of weeks ago where the Bolt’s 238 miles of range was insufficient. I needed to drive 300 miles (each way) to Arcata, California to attend the Humboldt Chamber Music Workshop at Humboldt State University. For a story on my happy week there, please see this story on Medium.

In any case, I surveyed the route online and found nothing much available for charging, so I borrowed a vehicle from the press fleet and pressed on. It was the gas-powered Ford EcoSport, a small crossover that occupies the bottom slot of Ford’s six-vehicle SUV menu. It did the job fine, but so would my Bolt–if the charging infrastructure was more developed. Here’s the EcoSport story

What I recommend for anyone considering an EV is to think carefully about how often you need to take a trip of more than the range of your car. In my case it’s perhaps two, maybe three times a year. That means that I can still drive all-electrically nearly all the time and then just borrow or rent a hybrid or gas-powered vehicle for those rare times when it won’t do the job. It sure beats burning fuel all year long just so you can have one car that does everything.

If you can’t do this, then a plug-in hybrid is still a reasonable choice. Just look for the most electric range you can get. The Bolt’s sibling, the Volt, does a fine job of enabling local driving with its 53-mile EPA battery range and carries an engine that kicks on when it’s needed to change the battery. That way, you’re free to go anywhere. The downside is that you still have an engine, radiator, oil, etc. to deal with like in an ordinary internal combustion engine (ICE) car. But driven mostly within the battery range, it’s essentially an electric car.

In summing up, as I’ve stated before, the Bolt EV has filled my needs so perfectly and pleasantly that it has become “my car,” rather than an object of journalistic attention. I keep a notepad in the car but only use it to write down interesting music I hear on my SiriusXM channels and custom license plates I see that I think might amuse my wife. This is good news, because other than the range limitations mentioned above, and availability of a place to plug in at home or work, there’s no reason why you can’t live happily with an EV.

Note: You may wonder why I haven’t posted a story here since April 16th. Other than my Bolt being completely familiar (nothing new to report) I have written seven stories on other vehicles and published them in the San Leandro Times, Tri-City Voice, and Clean Fleet Report. Please visit these sites if you want to read me regularly (All the EVs, hybrids, and alternative fuel cars end up on Clean Fleet Report).

More soon.

 

Acterra Shows How to Go EV

IMG_1914

On a beautiful Spring day in Palo Alto this Saturday, April 14, EV owners offered test drives and showcased their vehicles to attendees of the 2018 Earth Day Festival in Palo Alto. The event was put on by Acterra, a Palo Alto-based group that brings people together to create local solutions for a healthy planet. As an Acterra EV Ambassador, I brought my Kinetic Blue Bolt EV, and was joined by owners of Nissan LEAFs, Volkswagen e-Golfs, BMW i3s, Fiat 500Es, Teslas, and other popular electric vehicles.

I was one of the folks who left their car parked, and had many interesting conversations, answering questions and demonstrating features of the car, while helping people understand how much fun it is to drive an EV, and how we deal with their few shortcomings.

My car (the Blue Bolt EV) was first in line of the staged vehicles, next to a VW e-Golf and Nissan LEAF–two direct competitors.

IMG_1908

We owners had fun chatting when no visitors were around. Everyone has a story. The VW e-Golf next to my car was a late ’16, so the lease deal was amazing, after a significant down payment, just $75/month!. The white ’16 LEAF behind it, owned by my friend Greg, was purchased used, at a significant cost saving over a new one. And that’s a good example of how to get into EV driving without a huge initial outlay.

Not only were cars on display, but a number of them were also available for test drives, as seen by the orange Bolt, black BMW i3, and silver 2018 Leaf driving through the area in the photo below. This gave attendees a chance to get behind the wheel and viscerally sense the smooth, quick, quiet EV benefits. There were three Bolts available, as well as the two stationary ones, so we were well represented.

There were information booths, including Acterra, charger manufacturer ChargePoint, and the City of Palo Alto. I spoke with Hiromi Kelty, City of Palo Alto Utility Program Manager, who told me that 20% of Palo Altans drive EVs compared to 3% statewide. She also told me about the EV Charger Rebate that organizations in Palo Alto can receive when they install EV chargers – up to $30,000. For more information, go to cityofpaloalto.org/electricvehicle or call (650) 329-2241.

I showed my car to dozens of people, and had some interesting conversations. I allowed one 6-foot-5 man to adjust my seat, steering wheel, and mirrors to see if he fit in the car and could see if he was driving. The good news is that he did fit! The bad news is that it took a while to get my driving position back to normal. But I was glad to do it.

One man, who was sharing rides in his new Tesla Model 3, brought along a battery-powered skateboard. At $1,500, it an expensive toy, but could be useful for traveling between mass transit and your workplace, or for good clean fun. I declined a test ride.

IMG_1922

When the session was over, around 1:30, we put away our signs, folded our tents, and drove our EVs home. It felt like a worthwhile experience. I only hope that someone we spoke with will decide to get their own EV.

Chevy Bolt EV Easily Makes a 165-Mile Trip

Not long ago, owning an EV meant you were strictly limited on how far afield you could roam. The typical 70 to 80 miles per charge was a real issue.

That’s why, when I heard the Chevrolet Bolt EV had an EPA range of 238 miles, I knew it was the only choice for me. I couldn’t afford a Tesla, but really needed decent range.

I have a particular reason–my granddaughters live about 80 miles away and I wanted to be able to go visit them in my new car without stopping to charge. So yesterday, nearly three weeks after taking delivery, I made the 165.6-mile round trip.

My driving experience since getting my Bolt EV gave me confidence that I could do it. The driving range display gives estimated range, with “Max” and “Min” brackets above and below it, and the estimate appeared to be close to my actual mileage. But you never know until you try.

I filled my battery up on the Level 2 ChargePoint charger at work on Friday, and topped it off with my little 120-volt charger at home on Friday night. On Saturday, just before we left, the display looked like this:

img_7737

Note: That 203-mile figure is with the climate control on. With it off, the number would be about 10 miles higher.

We headed north and plugged in my wife’s iPhone to use Apple CarPlay to enjoy the James Taylor Greatest Hits album No. 1. It provided a soothing experience for a projected hour and a half on the road. I limited myself to 65 mph on the mostly freeway trip. I used the cruise control part of the time, and drove in Low, too. Low, with its greater brake regeneration, adds about 5 percent to the total.

We encountered some traffic in the MacArthur Maze in Oakland and around Petaluma (as usual), and inched along for a little while. Those two sections of the trip regenerated more energy than flying along unobstructed, and made the trip take a little longer. But I was encouraged that as we made progress, the projected range was staying higher than I expected it would.

After we pulled up in front of my son and daughter-in-law’s house, I examined the gauge:

img_7738

At an hour and a half, we had driven 82.8 miles, but the range indicator only moved from 203 to 144–or 59 miles. We had nearly three quarters of the battery charge left. That was fantastic!

We spent about four and a half hours with the family, and after a pleasant meal and much animated conversation and some hugs, we climbed back into the Bolt EV and headed home. I wasn’t worried about running out of charge on the way home.

This time, it was later, and traffic flowed steadily at 65 mph the whole way. That meant less opportunity to regenerate electricity, and we took more of a hit in the range. The final screen looked like this (darker because it was nighttime when we arrived home).

img_7740

This time, the 82.8 miles reduced the range by 91 miles–about 50 percent more than the trip up there–but not that far off from the actual traveled distance. We had less recharging ability, but saved a quarter of an hour of road time. 53 miles was a fine cushion. Our 165-mile trip showed up as 150 miles of range used. The Bolt EV passed my test.

The silence of the motor and smooth ride made our trip pleasant, the upgraded Bose stereo and Apple CarPlay kept us entertained, and I now know my Bolt EV will do the job!

 

Electric Fiat 500e- a Smooth Operator

Now nearly four weeks in to my electric car adventure with  Fidelio, the blue Fiat 500e, I’m really enjoying the smooth, powerful performance I get from him. Whether I’m zipping around town, accelerating onto the freeway, or climbing up the significant hills in my neighborhood, the little electric motor is more than up to the task.

Fascinating also is the way I can actually gain charge on a trip. Yesterday, I drove about four miles into Hayward, the next town over. The trip being mostly downhill or level, I ended up with a net range gain. I started with 46  on the range indicator and pulled into my destination with 51! Of course, I gave it back on the way home, but that’s the kind of numbers game you play when you’re driving an electric car today.

I keep coming back to the smooth, quiet experience I have every day commuting 18 miles each  way to work. I think the reason is that electric motors are much quieter, because they are so much simpler than gas engines. With just one moving part, the shaft, an electric motor creates virtually no vibration.The pistons of a gas engine move up and down, turning the crankshaft, which generates a lot of vibration and noise. That’s why there are engine mounts and mufflers. But you won’t find them in an electric car.

IMG_4597

I’ll admit that with its shroud, wearing the same dot pattern you’ll find on the front, sides, and back of the 500e, you can’t see much in this photo, but notice that there’s no fan or radiator here!

I found a nice little comparison online that explains the differences between electric motors and gas engines, in brief. It also shows why electric cars are cheaper to operate and require much less maintenance. The real issue remains the range and charging time, and I believe that will be mitigated in the near future, with better batteries and quick charging.

The bottom line for today, though, is to plan, so you have enough charge available. Your car sits most of the time anyway, so just be sure it’s plugged in! According to the dash readout in Fidelio, recharging from yesterday’s jaunts was going to take about 11 hours using household 120 current. So what? I was in my house hanging out and sleeping.
