Here’s a lengthy but excellent article from The Atlantic: “What If We Never Run Out of Oil?”
It certainly is an interesting concept – one that I find quite credible. For instance, we have recently discovered untapped reservoirs of methane hydrate (think of it as combustible ice) that collectively is the volume of the Mediterranean Sea. What happens when we develop the technology to extract, refine, and distribute it cost-effectively? (more…)
Here’s an infographic that summarizes some of the observations on the adoption of small modular nuclear reactors (SMRs). The reader will note that some of this stuff is so vague that it’s really valueless. For instance, Ambassador Hamad Al Kaabi, Permanent Representative of the UAE to the International Atomic Energy Agency says:
“More than 60 countries have expressed, to the IAEA, their interest in nuclear power, but when you look at grid sizes, many of these countries cannot accommodate a full-sized commercial reactor of today’s standard, given the size of their networks. You can assume that a lot of these countries – if they were actually going to develop nuclear power programs – would be looking at smaller capacity reactors.”
Anyone who takes this to mean that SMRs are right around the corner isn’t thinking very clearly. Personally, I’m one of the 83% who believes that the “lack of cost competitiveness with other forms of energy” is what will kill this, and render the whole discussion moot. The falling cost of solar, the already low levelized cost of wind energy will (actually already has) put a spear through SMRs.
Thanks to 2GreenEnergy supporter Don Harmon for alerting me to this wonderfully accessible piece on the environmental issues associated with lithium. If for no other reason, this is important because of the frequent argument that the potential for lithium shortages or the ecological hazards of mining the metals make the whole enterprise of lithium-ion batteries unsustainable.
Question: Most of us who follow the reports of our climate scientists understand that the average temperature of the Earth’s surface is rising. When was the last time in our planet’s history that the summer melting of the arctic ice was as severe as it is today?
Answer: Can be found at http://2greenenergy.com/cool-guess-answers/8732.
Relevance: Melting ice has the potential to cause a “runaway” effect with respect to global climate change, as the darker water absorbs more heat from the sun than the lighter colored ice, which tended to reflect that heat back into space.
I usually try to attend these Renewable Energy Finance Forums, though I’m going to skip this one, as it focuses on the Latin American and the Caribbean – a part of the world in which, sadly, I haven’t historically gotten too involved.
It sure would be good if I could change that, and somehow get a consulting “gig” to explore the migration to renewable energy down there. (more…)
2GreenEnergy supporter Steve Levy asks for my opinion and advice on getting a large number of small investors to back the development of solar energy projects. He sent me his latest paper – one that he presented at this year’s meeting of the American Solar Energy Society, dealing with creating a new kind of ‘investor,’ based on the agglomeration of micro-investments.
He notes: The issue that I am most interested in is, if 95% of the public believes that solar energy is what they want; then, what would be the entry level investment that the public would accept to become an investor in a MLP (master limited partnership)? How does one convince the public that it is a good investment? (more…)
I try to attend the annual University of California at Santa Barbara Summit on Energy Efficiency, now in its 4th year. This year’s meeting will focus on “Materials for a Sustainable Energy Future.” I plan to “join the Institute for Energy Efficiency and leaders from industry, academia, national labs and government to hear insights into the materials challenges, opportunities and latest developments relating to key technologies impacting energy efficiency.”
Outgoing Energy Secretary Steven Chu is speaking at this event, and, since I approve of him generally, I’ll make an extra effort to check out the talk. When we think of the unlovely convergence of energy and politics, it’s hard not to think of what Chu, a person of both passion and intellect, would have done had he not been handcuffed by the will of special interests. In fact, I may simply ask this question and see what happens. (more…)
My talk the other day to the Santa Barbara Savvy Investors’ Club went very well. As I told my wife when I pulled out of the driveway on my way, “It’s a room full of people who read a lot about sustainability. If I can’t do well with this demographic, I’m in trouble.”
If there were to be a problem, it would occur from “preaching to the choir.” After all, 45 minutes of a speaker’s telling you what you already know and believe can get a bit tiresome (more…)
There is so much general ignorance on the basic issues confronting renewable energy and electric transportation that it’s sometimes hard to know how to react to articles like this one on “vehicle to grid,” i.e., the concept that large number of EVs can eventually be used to provide power back to the electrical grid at times of peak load, or at least offer “ancillary services” in the form of wave-form regulation, etc. The average reader could infer that we’re somehow right around the corner from V2G, and this is most certainly not the case. In fact, in the four years that I’ve been attending conferences on the subject, I haven’t seen too much substantive movement in this direction; in particular, the technical standards under which all this will (or could) happen are still under discussion.
The good news is that the concept makes a great deal of sense. I.e., the introduction of significant quantities of battery storage will provide a number of benefits in addition to reducing/eliminating our dependence on gasoline and diesel, with their litany of negative environmental and political consequences. In addition to V2G, electric transportation will enable a large increase in the amount of wind energy we are able to generate and use productively, as the wind blows hardest at night, during off-peak periods.
It’s not news that there’s a growing trend towards building green homes, but what if you live in a home that’s not so green-friendly? Well, for starters, you’re not alone. In the U.S., there are about 125 million single-family homes with the majority being built before energy-efficient developments, according to the National Association of Home Builders. Don’t panic, it’s not too late to come to the greener side, and no you don’t have to demolish your green-less home and re-build a new one. Homeowners that want to make the switch to a greener home should consider a few modest upgrades that will put them on the right path to becoming a green-hero.
Start with an energy audit. An energy audit is exactly what you need when you’re looking to improve your home’s energy efficiency. An energy assessment will give you an evaluation on your home’s green status. It will determine where and how energy is being lost, which systems are operating inefficiently, and what cost effective measures can be taken to better green your home. (more…)
