Clean Energy: Good News Bad News

First some good news:

Corporate clean energy buying surged to new record in 2018

Corporations purchased 13.4 gigawatts of clean power through long-term contracts, more than doubling 2017’s total, helped by demand from new industries and previously untrodden markets

Scenery conflict (I’ll just add, that solar panels replacing some nice vistas is better than post-apocalyptic landscapes replacing some nice vistas): Rhode Island town grapples with how to promote solar and protect rural views

Similarly, Massive Wisconsin solar proposal splits farmers and clean energy fans

And … Oregon adopts strict rules for solar panel farms on high-value farm soil

And for those who want to pay more but perhaps have something cool: RGS Energy Revives Dow’s Solar Roof, Claiming Better Efficiency and Lower Costs

Minnesota Energy: Decarbonize, locally produce

The McKnight Foundation and GridLab contracted Vibrant Clean Energy, LLC, to prepare a report called Minnesota’s Smarter Grid: Pathways Towards a Clean, Reliable and Affordable Transportation and Energy System. Among other things, the report says:

The study has shown that the economy in Minnesota can decarbonize by 80% (from 2005 levels) by 2050. All the decarbonization pathways involve deeper energy efficiency of existing electric demands (particularly in the industrial sector), heavy electrification of transportation, transitioningheating of space and water from natural gas and resistive heating to heat pumps, building new zero-emission generation technologies, and retiring fossil-fuel generation.

The electrification of other sectors provides the electricity sector with new demands, which have different load profiles to existing demands and have greater flexibility potential. These new loads provide increasing sales for the electricity sector to invest against. Further, the greater flexibility allows the electricity grid to incorporate more variable resources, which are low-cost and nearzero emissions. Further, the electrification provides net cost savings for consumers because the reduction in spending on other energy supplies (natural gas for heating and gasoline for transportation) outweighs the additional spending in the electricity sector for the electrified loads.

Decarbonizing the not so low hanging fruit

We, we humans, need to stop releasing fossil carbon into the atmosphere well before 2100 or we are doomed.

The main reason we are not heading headlong into that project, getting it done right away, is because of the fossil fuel industry combined with a deep seated self-hate on the part of Republicans, who would rather end civilization and make all of our children suffer than to do something an environmentalist might suggest.

The road to decarbonization is the same as the road to electrification plus the road to making all of our electricity with something other than coal, oil, methane, and the like. This could involve a certain amount of liquid fuel that is generated using wind and solar power, and magical bacteria or something, perhaps with a mix of plant material or other bio-sources.

There are easy ways to do part of this fast. For example, building wind farms is easy and produces piles of electricity. Same with solar. “But wait wait,” you say. “Those sources are intermittent, we can’t…” But I say to you, if this is your first thought, you are out of date (or are a Republican?). Solar and wind are indeed intermittent, but we can still use them as the backbone of our power system. This is a problem, but not one that can’t be figured out and has been, in fact, largely solved using a number of approaches. And, that is off the topic of this post.

We can also put solar panels on our roofs to a much greater degree than we do now. It has been estimated that a reasonable, not overdone but pretty thorough, deployment of PV panels on the roofs of America would cover about 40% of our in-building electrical needs as they stand now. This added to the eventual (though expensive, yet easy) deployment of heat pumps and total electrification of everything in those buildings probably averages out (the heat pumps reduce energy demand, the electrification increases demand for electricity as compared to gas or oil).

There are other types of low hanging fruit as well, such as increasing efficiency, telecommuting.

But what about the hard to do stuff, the major uses of energy that can’t be changes so easily?

There is a new review paper out in Science that discusses this. The paper is:

Net-zero emissions energy systems, boy Steven Davis, Nathan Lewis, Matthew Shaner, et al. Science 360(6396).

If you click on that link, you might be able to see the paper, as I think it is OpenAccess.

The paper identifies the following areas as tough nuts to crack:

  • Aviation
  • Long-distance transport
  • Shipping
  • Steel production
  • Cement production

It identifies the following technologies as helpful:

  • Hydrogen and ammonia fuels
  • Biofuels
  • Synthetic hydrocarbons
  • Direct solar fuels

The paper also identifies “highly reliable electricity” and energy storage as key areas of further development.

I do not see any major surprises in this paper, but that is because it is a review paper. I think it is a useful read to help organize one’s thinking on the transitions we will attempt, should the Republicans allow it, over the next decades.

Nuclear Plant Bill Riles, Confuses, Perhaps Conspires

There is a pair of bills working their way through the Minnesota state legislature that would change the way Xcel Energy can pay for certain costs of maintaining and upgrading its nuclear power plants between now and their eventual final shut down several years hence.

The Best US Electricity Generation Graphic Ever, No Kidding

Carbon Brief has produced a US based (sorry, rest of the world) interactive graphic that accesses an extensive underlying database that shows everything about the electricity generation that there is to know. Each generation plant, each type of electricty, capacity, etc. and you can view the information by state, by type of energy, and with some other toggles.

Here is an example. Continue reading The Best US Electricity Generation Graphic Ever, No Kidding

Climate and energy are becoming focal points in state political races

Just a pointer to my colleague John Abraham’s current post in The Guardian:

The latest example, Minnesota gubernatorial candidate Rebecca Otto has a strong clean energy proposal

As soon as Donald Trump won the presidential election, people in the US and around the world knew it was terrible news for the environment. Not wanting to believe that he would try to follow through on our worst fears, we held out hope.

Those hopes for a sane US federal government were misplaced. But they are replaced by a new hope – an emerging climate leadership at the state level and a continuation of economic forces that favor clean/renewable energy over dirty fossil fuels. In fact, it appears that some states are relishing the national and international leadership roles that they have undertaken. Support for sensible climate and energy policies is now a topic to run on in elections.

This change has manifested itself in American politics. One such plan stems from my home state, but it exemplifies work in other regions. I live in the state of Minnesota where we are gearing up for a gubernatorial election, which is where this plan comes from.

My state is well known as somewhat progressive, both socially and economically. The progressive policies resulted in a very strong 2007 renewable energy standard, which helped to reduce carbon pollution and create 15,000 jobs.

As an aside, it is really painful for me to…

Puerto Rico, now’s your chance!

Puerto Rico can become the first significant size polity to rebuild itself from the ground up to be totally Carbon free. Or at least, that seems like a good idea. If only the US Government wasn’t so anti-Puerto Rico, owing to the president being, well, Trump.

Anyway, there is now a pile of money and effort pouring int Puerto Rico and this can be used in part to give Puerto Rico sigificantly more economic and energy security in its future, if only energy-smart decisions are made now. So let’s see what Get Energy Smart Now blog has to say about this!

Puerto Rico’s electricity system, prior to Maria, heavily relied on centralized diesel power generation with above-ground power transmission: very high cost electricity, dependent on continued fossil-fuel imports, with great vulnerability to disruption.

Post disaster, thoughtful policy and efforts would seek to maximize value in the Disaster 4R chain: relief, recovery, reconstruction, and resiliency against future impacts.

Rapid deployment/installation of solar-power centered micro-grids to Puerto Rico is a clear example of a Disaster 4R.

Here are some rapid thoughts as to such a Solar Disaster 4R package.

Go HERE to see the bullet pointed suggestions which could ultimately lead Puerto Rico into the next era of energy planning and development. As noted in the bullet points of the post, the success and validity of any such overhaul is based on it coming from the Puerto Rican society, economy, and local population.

States Can Lead the Way on Climate Change

True that. In the US, energy policy and regulation happens much more at the state level than the federal level, and our federal government went belly up last January anyway. Some states will not lead, they will go backwards, but others will lead, and show the way.

So, here I want to highlight this new item in Scientific American by Rebecca Otto.

States Can Lead the Way on Climate Change
The Trump administration’s threats to abandon Obama’s Clean Power Plan and exit the Paris accords don’t necessarily mean all is lost

The word “corporation” does not appear in our Constitution or Bill of Rights. But as Rhode Island Sen. Sheldon Whitehouse notes in his book Captured, corporations had already grown so powerful by 1816 that Thomas Jefferson urged Americans to “crush in its birth the aristocracy of our moneyed corporations, which dare already to challenge our government to a trial of strength, and bid defiance to the laws of our country.”
Today the conflict between the unfettered greed of unregulated capitalism and the right of the people to regulate industry with self-governance has reached extreme proportions. Corporations now have more power than many nations and feel justified in manipulating democracy to improve their bottom lines instead of the common good.
Nowhere is this problem more pronounced than…

Then where? THEN WHERE??? Go read the original piece!

Rebecca Otto’s Clean Energy Plan for Minnesota

Earlier today, Minnesota Gubernatorial candidate Rebecca Otto released her energy transition plan. It an ambitious plan that puts together several elements widely considered necessary to make any such plan work, then puts them on steroids to make it work faster. To my knowledge, this is the first major plan to be proposed since the recent dual revelations that a) the world is going to have to act faster than we had previously assumed* and b) the US Federal government will not be helping.

Here’s the elevator speech version: Minnesota residents get around five thousand dollars cash (over several years), monetary incentives to upgrade all their energy using devices from furnaces to cars, some 80,000 new, high paying jobs, and in the end, the state is essentially fossil fuel free.

About half of that fossil fuel free goal comes directly from Continue reading Rebecca Otto’s Clean Energy Plan for Minnesota

Rebecca Otto’s Clean Energy Plan for Minnesota

Earlier today, Minnesota Gubernatorial candidate Rebecca Otto released her energy transition plan. It an ambitious plan that puts together several elements widely considered necessary to make any such plan work, then puts them on steroids to make it work faster. To my knowledge, this is the first major plan to be proposed since the recent dual revelations that a) the world is going to have to act faster than we had previously assumed* and b) the US Federal government will not be helping.

Here’s the elevator speech version: Minnesota residents get around five thousand dollars cash (over several years), monetary incentives to upgrade all their energy using devices from furnaces to cars, some 80,000 new, high paying jobs, and in the end, the state is essentially fossil fuel free.

About half of that fossil fuel free goal comes directly from the plan itself, the other half from the economy and markets passing various tipping points that this plan will hasten. The time scale for the plan is roughly 10 years, but giving the plan a careful reading I suspect some goals will be reached much more quickly. This means that once the plan takes off, Minnesotans will have an incentive to hold their elected officials accountable for holding the course for at least a decade.

The central theme of the plan is to use a revenue-neutral carbon price, which is widely seen by experts as the best approach for cleaning up our energy supply. The simple version of the carbon price works like this: Releasing carbon is saddled with a cost, way up (or early) in the supply chain. So you don’t pay a gas tax or any kind of energy tax, but somewhere up the line the big players are being charged for producing energy reliant on the release of fossil carbon. They, of course, have the option of producing electricity from wind and solar.

The campaign notes, “Rebecca’s Minnesota-Powered Plan doesn’t raise taxes a single penny. It levies a carbon price on fossil fuel companies, and pays 100% of the revenue back to Minnesota residents, so we can take charge of our own energy.”

That money is then distributed to any citizen who wants it (of course they will all want it), evenly, across the board. So, in theory, your cost of living is a little higher if dirty energy producers are in your own personal supply chain, but lower if they are not, and in any event, you are paid off to not care. The point is, if you personally eschew fossil carbon releasing products or energy sources, you get the payoff and someone else is paying for it. That would apply to both individuals and companies, because companies can often make those choices. For example, a school bus company would be more likely to replace an old dirty bus with an electric bus rather than a propane bus. (Just yesterday, an electric bus set a record, going over 1,000 miles on a single charge! Electricity is some pretty powerful magic.)

The Otto plan has a twist. While 75% of the carbon price is distributed evenly and directly to all citizens, 25% is distributed as refundable tax credits intended to cover 30% of the cost of clean energy improvements that use Minnesota companies. This may include solar panels, heat pumps for heating and cooling, insulation, new lighting, etc. New or used electric cars count. So it all goes back to the people, but some of it is directed to support the energy transition for individuals and families.

(A “refundable credit” is a tax credit that you still get even if you did not pay enough taxes to use it, so people of any income will be able to access the clean energy benefits.)

The conservatively estimated potential cash gain for a typical Minnesota family is laid out in this table from the Otto campaign:

That is for one year. As the plan matures, a decade down the line, we can assume the carbon price component will diminish, but the household payback for being off fossil fuels will increase, and, guess what? The plant gets to live and your children don’t have to live in as much of a dystopian future!

The clean energy technologies that will need to be deployed mostly already exist, and most of them can be processed and supplied right here in Minnesota. Indeed installing PV panels and car chargers, or efficient heat pump based furnaces, etc. is the kind of job that can not be outsourced to some other country, because your house is here so the work gets done here! It is estimated that some 80,000 long term high paying jobs will be generated from this infrastructure redo. That will in turn increase revenues to the state and quite likely, will spell surpluses, some of which are likely to be tax rebates or other sorts of payoffs to the citizens of the state.

A quick word about the Coal-Car Myth. Some will read about this plan and say, “yeah, but … if I drive an electric car and stuff, that electricity is even worser because it is made with dirty coal and stuff.” (Yes, I make the Coal-Car Mythers sound a bit dull because, at this point, you’d have to be a bit dull to still be thinking this). First, know this: There are circumstances under which burning coal to make electricity to charge a car will be more efficient than running a gasoline car. To conceptualize this, imagine two engineering teams in a competition. One is to make an energy plant using coal, the other is to use an energy plant using only 6 cylinder Ford motors. The winner builds the plant that is more efficient. The team using the thousands of internal combustion engines will lose. Second, know this: It is simply not the case that all of our electricity comes from coal, and every week there is less and less of it coming from coal. Electric cars have the promise, by the way, of outlasting internal combustion cars on average. So, over perhaps half the lifespan of a given electric car, what might have been a tiny increase in efficiency for a small number of electric cars (the rest start out way more than tiny) will become a great efficiency. It is time to switch to electric cars in Minnesota.

You can expect opposition to this plan from the likes of the Koch brothers, who are currently spending just shy of a billion dollars a year, that we know of, to keep fossil fuel systems on line and stop the clean energy transition. I asked Rebecca Otto what she expected in terms of push back. She told me, “Investing in clean energy means investing in our communities and taking charge of our own energy, instead of subsidizing big oil. Hence, big oil will be the stumbling block, as this will affect their bottom line over time.”

I asked Rebecca why this is something that needs to be handled by the states, rather than at the national level. She told me, “The crippling dysfunction in Washington is persistent and we need to act now. Oil companies are spending billions of dollars to rig the system against clean energy solutions. We need to break their stranglehold on our democracy and put people, not oil companies back in charge.”

She also noted that “we also have a moral imperative to do something and the federal government has become paralyzed by big oil propaganda and political spending. The states could become laboratories to begin to tackle climate change. And whoever does is going to reap the economic benefits from the job creation. These jobs pay 42% higher than the state’s average wage.”

Economists say the carbon price is the best way to make the energy transition happen. Regular Minnesotans benefit the most, the Minnesota economy benefits, and the environment benefits. This is a good plan. I endorse it.

This plan, which you should read all about here, has also been endorsed by the famous and widely respected meteorologist Paul Douglas, by Bill McKibben of 350.org, St Thomas scientist and energy expert John Abraham, and by climate scientist Michael Mann.

I’ve got more to say about this plan and related topics, so stay tuned.

Here’s a video of Rebecca Otto discussing energy from the roof of her solar paneled home, with her windmill generating electricity in the background. Apparently, she walks the walk!

Powering Minnesota to prosperity through energy leadership


*You may have seen recent research suggesting that we have more time than previously estimated to get our duck in a row with clean energy. That research was misrepresented in the press. A statement made by one of the authors clarifies: “..to likely meet the Paris goal, emission reductions would need to begin immediately and reach zero in less than 40 years’ time.”

Australia Solar Thermal Plant: Messed up reporting

SolarReserve will build, for the South Australia government, a solar thermal plant rated at 150 MW, which is about 25 MW more than that government uses currently. Over time, assuming Australia goes all on clean and green, the amount of electricity used by South Australia will increase substantially, but for now, this plant will provide the extra to the regional grid.

A solar plant is a way of making the use of solar more full time. Instead of just producing electricity by sunlight, perhaps storing some in batteries, it uses sunlight to produce heat, which is then used to run a turbine all day and all night, and across periods of cloudiness (which are rare in the case of this particular plant’s location).

Putting it another way, this kind of plant solves the problem that clean energy tends to be intermittent. Putting it still another way, this kind of plant reduces the need to store electricity that may be overproduced or produced irregularly by photovoltaic solar or wind plants.

But the reporting of this story sadly demonstrates counterproductive lousy anti-clean energy commentary delivered in an envelope of crap reporting (because the reporter did not understand the story enough to ask the right questions). Here is a quote from the story in The Guardian

<blockquoteWasim Saman, professor of sustainable ernergy engineering at the University of South Australia, said solar thermal was a more economical way of storing energy than using batteries.

“The significance of solar thermal generation lies in its ability to provide energy virtually on demand,” he said.

But Dr Matthew Stocks, a research fellow in the research school of engineering at the Australian National University, said solar thermal also had limits.

“One of the big challenges for solar thermal as a storage tool is that it can only store heat. If there is an excess of electricity in the system because the wind is blowing strong, it cannot efficiently use it to store electrical power to shift the energy to times of shortage, unlike batteries and pumped hydro,” he said..

No. Investing in this kind of plant is a move to reduce the problem of storage.

Show me an article about a new nuclear power plant, an upgrade to a coal plant, or a new natural gas plant, that mentions that these technologies are not batteries. This is nothing other than a senseless contrary opinion pulled out of the nether regions of a reporter’s notebook. The search for false balance continues even at the Guardian, which really should know better.
