When Will Renewable Energy Prices Stop Dropping?

June 15th, 2019 | by George Harvey

Some people have asked when the prices will stop falling. Their understanding is that the decline in price really is unpredictable, and they believe that no definitive answer can be made about what source of energy will be least expensive in the future. In some important ways, they are wrong. The declines are predictable, to a degree


Nuclear Power Is Not Safe

May 13th, 2019 | by George Harvey

One nuclear industry safety assessment figure claims risks are only one-tenth as great as the historic record shows they are. If the people in the industry know it, they are not admitting to a serious safety problem. If they don’t know it, they are simply ignorant of their industry’s record. Either way, I think it is clear that nuclear industry safety analyses should be regarded as untrustworthy


Pity The Poor Republican Party

November 5th, 2018 | by George Harvey

Miami is the home of almost half a million people. Its real estate has immense value. But Miami is built on porous sandstone, so even a seawall will not save it because the water flows right through the rock it is built on. To makes matters worse, Miami is just one of many communities in its area that are threatened. It is a problem across the whole southern end of Florida


If Trump Rejects The IPCC Report, He Is Giving China A Powerful Weapon

October 10th, 2018 | by George Harvey

One thing Trump clearly does not understand is that trade wars are won by cutting off the competition from its suppliers and customers. This means isolating the enemy. It implies building alliances and cutting the enemy off from its friends. This is something that probably cannot be done by an isolationist country


Trump’s Trade War – Headed for Catastrophe

September 26th, 2018 | by George Harvey

When I wrote “Trump Is Already Losing The Trade War,” last March, I did not envision things going quite this badly for him quite this fast. Here it is just six months later, and I think it is possible to predict that Trump’s America can only suffer increasing losses as the catastrophe goes on


Refurbishing Baseload Power Stations To Backup Renewables

September 4th, 2018 | by George Harvey

A number of stories have popped up in the news recently about turning traditional hydroelectric stations, which generate power by using water captured from a flowing river, into pumped storage facilities, which cycle the water using more energy to do so than they produce


Where Are New Grid Tech Investments Going?

July 25th, 2018 | by George Harvey

On July 24, Mercom Capital Group (MCG) released its “Q2 2018 Battery Storage, Smart Grid and Efficiency Funding and M&A Report.” The report is available online, though it is a bit pricey at $299 to $499. Mercom Capital Group is a highly regarded clean energy consulting firm with worldwide influence. Its new report provides a picture of mergers and acquisitions (M&A) and other funding that took place during the second quarter in the fields of battery storage, smart grid, and energy efficiency


Trump Fiddles As Fossil Fuels Burn

June 4th, 2018 | by George Harvey

Coal and nuclear power are both dying, falling victim to natural gas and renewable energy. Trump used to blame the Democrats, and especially “Obama’s war on coal.” He used to take the position that removing subsidies for renewable power would be sufficient to bring a renaissance to the coal industry. But despite his efforts, coal plants have just kept closing


Elon Musk Harpooned Baseload Power

May 15th, 2018 | by George Harvey

With batteries like the Hornsdale Power Reserve, power from solar and wind power will be more valuable, because with battery backup their power can be used to supply an increasing share of baseload power. And that increase in value, which might not necessarily be reflected by an increase in price, makes their power all the more attractive


Power To Methane

May 14th, 2018 | by George Harvey

The idea behind power-to-gas has been around for a while. It uses electric power to produce gaseous fuel, usually hydrogen. The advantages are that it can be used to take up excess electric energy from renewable generation in a chemical form. Later, the fuel can be used as needed.


How Long Will PV Prices Continue To Fall?

April 30th, 2018 | by George Harvey

Prices of solar photovoltaic (PV) systems follow economic laws just like other things, such as computers and cars. That does not mean that the precipitous drop in prices will slow, however.


A Trade War With China Will Be A Tough Ballgame

April 3rd, 2018 | by George Harvey

Donald Trump, and those who support him, have good reason to be afraid of China in this tough game of hardball. China is in the ball park, ready to play. But the President of the United States, who issued the challenge, is in a sandbox holding a small bag of marbles


Trump Is Already Losing The Trade War

March 28th, 2018 | by George Harvey

Donald Trump has failed to understand one essential point about a trade war. To win it, you need friends. In that ignorance, he is antagonizing customers at the very time his competition is courting them.


Don’t Bet On A Decline In Chinese Solar PV Production

March 19th, 2018 | by George Harvey

Chinese domestic demand for solar cells and modules is projected to decline. Combined with the growing protectionism, this is expected to produce a difficult period for the Chinese solar industry, according to reports. They say it looks like gloomy times are coming for the Chinese solar industry. My advice is, “Don’t bet on it.”


The Community Microgrid As A Virtual Power Plant

January 24th, 2018 | by George Harvey

The design for a community microgrid project that is forming in Warner, New Hampshire, seems rather prosaic at first glance. It is simple, with a few buildings, some solar panels, batteries, inverters, and all the regular gear. It seems an appropriately small start for a town with only 444 people in its center and a total population well below 3,


Renewable Energy Grid Parity Confusion, Old Data, & Media Errors

January 15th, 2018 | by George Harvey

The International Renewable Energy Agency (IRENA) has been much in the news since it released its report Renewable Power Generation Costs in 2017. Article after article has told us that it said we could see the costs of renewable energy drop to meet those of fossil fuels by
