New nuclear power for New York

July 9, 2025 By EarthWise Leave a Comment

New nuclear power plant is coming in New York

Nuclear power has been around since the 1950s, but it has fallen out of favor in recent decades, in part due to a couple of traumatic disasters at nuclear power plants.  In fact, only two new nuclear power plants have been built in the US in the past 30 years, and they took a very long time and an enormous amount of money to build.

However, in recent times there has been a great deal of developmental work on nuclear power.  Such newer technologies as small modular reactors, molten salt reactors, light water reactors, and more hold promise for safer, less expensive, and higher performance nuclear power.

In late June, New York Governor Kathy Hochul announced that she has instructed the New York Power Authority to develop and construct a zero-emission advanced nuclear power plant in Upstate New York.  The plant is to produce 1 GW of power, about half of what the decommissioned Indian Point Power Plant produced when it provided significant amounts of power to New York City residents.

Renewed interest in nuclear power has emerged in part because of the soaring electricity demand from AI data centers.  Companies like Amazon, Google, and Microsoft have all begun investing in nuclear power for this reason.

NYPA is instructed to begin evaluating technologies, business models, and locations for the new power plant and will seek to secure key partnerships needed for the project.  As things stand, it is not known what technology the plant will use, where in Upstate New York it will be located, how much it will cost to build, who will pay for it, and how long it will take to build.

A Big Year For Rooftop Solar | Earth Wise

July 19, 2023 By EarthWise Leave a Comment

Rooftop solar growing around the globe

The global capacity of rooftop solar power grew by 49% in 2022.  Overall, the installed amount of rooftop solar grew from 79 gigawatts to 118 gigawatts last year and it is projected to reach 159 gigawatts by the end of this year.  By comparison, a typical nuclear power plant can produce 1 gigawatt; a gas-powered power plant is typically half a gigawatt.

Rooftop solar constitutes a relatively small fraction of the total global installed solar capacity, which is dominated by utility-scale solar arrays.  Total installed solar capacity rose from 950 gigawatts to 1,177 gigawatts last year and is projected to reach 1,518 gigawatts this year.  That is enough power to meet more than half the electricity demand of the European Union.

The rapid growth of solar power can only continue if there is more energy storage put in place to manage the peaks and troughs in solar output.  Countries will also need to upgrade their power grids to be able to transport excess solar power from where it is generated to where it is needed.   Bottlenecks in the grids of most of the leading solar-producing nations are already interfering with further solar development.

The overall potential for rooftop solar is based on the number of rooftops that would be suitable for solar power, which depends on the size, shading, orientation, and location of the roofs.  According to the National Renewable Energy Laboratory, rooftops in the United States have the potential for more than 1,000 gigawatts of solar capacity. Currently, only about 4% of US homes have rooftop solar.

Coronavirus And European Energy | Earth Wise

Coronavirus Boosts European Renewable Energy

As people all over the world shelter in place and much ordinary commerce and other activities have ground to a halt, there have been big changes in energy usage.   With production halted, offices shut down, schools closed, and public transport operated on reduced timetables, the demand for energy has decreased dramatically.

In Europe, as a result of all this, during the first quarter of this year, renewables’ share of total energy production was greater than 60%.  Wind farms provided more than 40% of the renewables’ share of total electricity generation.   During February, Denmark, Germany and Ireland saw nearly 50% of their electricity demand met with wind power.  Hydroelectric power was the second largest source of renewable energy during the first quarter, with Norway providing the largest share of this.  In contrast, generation from nuclear plants was at its lowest first quarter figure for the past five years.

The large shift to renewable generation was in great part due to the overall reduction in demand.  This impacts nuclear and fossil-fuel generation much more than renewables because those plants can be throttled back or shut down entirely so as not to needlessly consume costly fuels.   Generation that runs on sunlight, wind, or flowing water does not require fuel expenses, so it makes sense to prefer them when demand is reduced.

The reduction in demand has in turn had a major effect on fuel costs as oil reached low prices that haven’t been seen in years.

The decline in demand and fuel prices and the enhanced role of renewables are expected to continue in the current quarter as the timetable for renewed economic activity remains unknown.

Energy From Jellyfish

Jellyfish are fascinating in appearance but generally are nothing but trouble.  Their stings can ruin a tropical vacation but they can cause far more damage than that.

Long Island Wind

The Interior Department has recently defined a “Wind Energy Area”, consisting of about 81,000 acres, located 11 miles south of Long Island.  The designation is a first step to opening up the acreage for large-scale, competitive wind energy leasing through the Bureau of Ocean Energy Management.
