Guest Blog by S. A. Shelley: The last decade has seen an explosion of new digital tech incessantly infiltrating all areas of our lives. There were cells phones before 2010 as well as websites and such, but with the advent of smart phones, 5G, the internet of things, everything is now wirelessly connected. New things such as crypto currency and EVs have also made significant inroads into society in the last 10 years. Many of these technologies are, of course, promoted as green and helping the world. Such is always the case when new technologies arise, and there are enough people to advocate for their favorite thing: Bud or Bud Light, Democrat or Republican, Trudeau fan or intelligent person.Continue reading New Digital Tech Solutions Equal More Old Energy Tech

What’s up with the Texas power grid?
OWOE Staff: So what’s going on with the power grid in Texas? Last week the state was hit by a polar vortex winter storm (Uri) that brought snow and ice and record low temperatures. Such storms aren’t especially rare – it snows and ices in Houston about every ten years. But this time it created one of the biggest power outages in US history (Fig 1), and the Texas power grid came within minutes of failure. Then the real fun began. The Governor blamed the power failures on the wind turbines in West Texas freezing up, but had to retract the comment almost immediately when the grid operator, ERCOT (Electric Reliability Council of Texas), announced that the majority of the power outages were due to gas supply shortages and freezing of the conventional thermal power plants. A former Texas Governor claimed that Texans would rather endure power failures than have more regulation of the industry. Senator Ted Cruz, from Texas, who had a history of denouncing renewable energy as the cause for California’s power outages fled the cold to take his family to Cancun and immediately had to fly back due to public outrage. A photo of a helicopter deicing wind turbines in Texas went viral as an example of renewable power being dependent on fossil fuel and chemicals, until the photo was identified as actually being an extreme case of deicing an old-style turbine in Sweden from 2014. Texans who signed up for electricity plans that charge based on wholesale electricity prices are now facing bills in the thousands of dollars. Etc, etc.Continue reading What’s up with the Texas power grid?
Green Energy in Germany, How’s it Really Going?
Guest blog by S. A. Shelley: With so much talk about Green New Deals (U.S.A.) and a Green Way Forward (Canada) these days, I thought it might be worth looking at the poster child for green energy, Germany and its frequently lauded Energiewende . Way back in 1971, the Germans started thinking about ways to shift their energy mix in order to promote sustained economic prosperity, especially, at that time, in the face of Global authoritarian (communist) threats. It was necessary then to find ways to reduce West Germany’s dependence on the Soviet bloc for energy supplies. After all, in case of war, one cannot expect one’s enemy to continue supplying fuel for one’s tanks and jet fighters.Continue reading Green Energy in Germany, How’s it Really Going?
The latest push for fossil fuels – rhetoric or reality? Part 1 – Coal
By W. H. Luyties, editor OWOE. With the election of Donald Trump as president of the US and control of all 3 branches of the government in the hands of Republicans, who have historically been strong supporters of fossil fuel interests, one lightning rod topic has been the push to increase coal and oil production in the US. This has energized both proponents of fossil fuels, who see an opportunity to possibly save their industries (coal) or increase production (petroleum), and opponents, who fear the environmental consequences of such a change. But is this a real threat to the global move away from fossil fuels, or is it simply rhetoric to energize a political base? Continue reading The latest push for fossil fuels – rhetoric or reality? Part 1 – Coal
Net Metering: A brilliant concept whose time has passed?
There is no doubt that the practice of net metering for residential solar photovoltaic systems has been a key enabler of the rapid growth of rooftop solar generation in the United States (see OWOE: How does net metering encourage private investment in home solar systems?). But has it outlived it usefulness? Or, has it even become a barrier to greater renewable penetration into the marketplace?

Peak Oil vs Peak Coal
Last month’s OWOE blog “Did the World Hit Peak Oil in 2015 and Nobody Noticed?” generated some interesting discussion. One follower raised a very good question regarding whether we have compared the fate of the oil industry with the fate of the coal industry in terms of the effect of oil and gas as disruptive technologies. Since it’s been some time since we touched on coal, now is an ideal time to use this question as a lead-in to the broader subject. The simple answer is “yes”, as the relatively recent rapid decline in coal production and usage has been a demand driven phenomenon caused by many of the same issues as we are seeing with coal. If we look only at the US, peak coal occurred in 2008, as illustrated in this figure from the Energy Information Administration (EIA).
A real world case for renewables – Puerto Rico
Islands represent unique challenges for supply of energy. By nature they tend to be distant from conventional, large scale energy sources, and they tend to lack natural resources necessary to produce power locally, which is particularly true for small islands. A case in point is Puerto Rico. This month my wife and I traveled to Puerto Rico for the first time for a much-needed vacation. Dealing with, or even thinking about, energy was one of the furthest things in our mind. However, two days into our stay, energy became the most important aspect of our vacation. Continue reading A real world case for renewables – Puerto Rico
Toxic Nature of Energy Dialogue in the US
A perfect example of the toxic nature of the energy dialogue in this country arose last week in Southern California. There has been a long running environmental disaster north of Los Angeles involving a methane gas leak from an injection well at the Southern California Gas storage facility near the town of Aliso Viejo and the community of Porter Ranch. Continue reading Toxic Nature of Energy Dialogue in the US
Recent Controversy over Renewable Energy Credits
As another example of the complexities of energy in today’s world, we have the latest controversy surrounding Renewable Energy Credits, (RECs – pronounced “wrecks”). A REC is a financial tool in the form of a certificate that represents the generation of one megawatt-hour of electricity from a renewable energy source. RECs are not tied to the physical delivery of electricity and can be bought and sold on the open market. For example, a utility that has been mandated to generate a minimum level of electricity from renewable sources can buy RECs as opposed to developing their own sources or purchasing green power from another provider. A company that produces renewable power earns RECs and can then sell them. The benefit to the purchaser is to be able to take credit for the green power and meet their commitments at an acceptable cost, while the benefit to the seller is receiving income to offset the cost of their investment.

Paris Climate Change Agreement and More
December has been another big month for the environment with the United Nations Conference on Climate Change (also referred to as the Paris Climate Talks and COP21) ending in a broad, world-wide agreement to reduce greenhouse gasses in an attempt to combat global warming. The agreement confirmed the target of keeping the rise in temperature from the pre-industrial world to below 2°C, which scientists believe is necessary to prevent a global catastrophe. The agreement even establishes for the first time, that the world should be aiming for a rise of only 1.5°C to protect island states, which are the most threatened by the rise in sea levels. The Paris agreement requires all countries to review their contributions every five years from 2020; they will not be able to lower their targets and are encouraged to raise them. In addition, countries will aim to achieve carbon neutrality in the second half of the century. See CPO21 for more information. Continue reading Paris Climate Change Agreement and More
