Leen Weijers wow, I knew it was expensive....and impossible, but your analysis is spot on, and needs significant attention. How is it the Biden administration thinks offshore wind, no less, makes any sense...in the mean time we are destroying our marine habitats for useless generation that is not going to show up on time and when needed at an incredibly high expense to the rate payers. #wind #intermittent #costprohibitive #notgreen #unreliable #thermodynamics #secondlaw

A complicated way to ask for 12 GW of wind power to work as reliably as a nuclear, coal, or natural gas power plant. see also: https://lnkd.in/etwTyAm8 #missionimpossible #windenergy #energietransition #klimat

Thank you Leen Weijers! There are several misconceptions when renewables supporters discuss wind and solar. The difference between MW nameplate rating and MWH rating is one. Another widely misunderstood concept is the difference between PRIMARY and SECONDARY Energy. Thanks for providing some easy to understand explanations #Climatepolicy#Energypolicy #EnergySobriety

When Lazard calculated how wind power cost change by “firming” it with battery backup, it grossly underestimated wind’s intermittency and its impact on Levelized Cost of Energy (LCOE). I reviewed 2022 wind power data for Texas, as measured by ERCOT, to determine what battery it would take to ensure that 34% (TX wind capacity factor) of the nameplate 35 GW wind capacity works 95% of the time. Sorry, that is a complicated way to ask for 12 GW of wind power to work as reliably as a nuclear, coal or natural gas power plant. TX wind misses the required 12 GW 45% of the time with its current ~10 GWh storage backup. In what Lazard calls "firmed" wind power with 4-hr of battery backup, wind power under-delivers 35% of all time. To decrease the power shortcoming to only 5% requires a whopping 7 TWh in battery storage. That’s 700x the size of today’s battery system and increases wind power LCOE 30x from about $40/MWh to 1,200/MWh. There are other ways to ensure reliable power at low cost, but cheap & reliable wind power is an oxymoron.  https://lnkd.in/eyHFC6CC #renewables #batterystorage #windenergy #energytransition #LCOE

Let the grumbling begin! #PJM #Capacity auction results cleared - Massive jump - Nearly 10x jump. According to @pjminterconnection the power mix from generators included 48% gas, 21% nuclear, 18% of coal, 1% of solar, 1% of wind, 4% of hydro, 5% of demand response and 2% from other resources. #energy #power #electricity #renewables #prospectresources

What are the three primary categories of power systems? Generation: True to its name, the generation system produces and exports power. It encompasses various sources, including gas engines, power stations, nuclear power, renewable energy, and tidal schemes. Load: This system imports power and applies to any setup lacking internal power generation. Examples include industrial sites, data centers, residential areas, and commercial supplies. Storage: As the name implies, the storage system retains power. Storage is increasingly prevalent and involves accumulating energy from renewable sources, such as solar and wind power, often stored in batteries, and pump storage. This foundational knowledge is both elegant and imperative.

Solar is booming in the United States as power demand surges, outpacing the growth of any other electricity source and disproving claims that the energy transition is a failure. To be sure, solar remains a small portion of total electricity generation in the U.S., standing at just 3.9% of the nation’s power mix in 2023 compared to the 43% share held by natural gas, according to the Energy Information Administration, the statistical unit within the Department of Energy. 🔗Read more about this story and our other notable updates mentioned below in this week's Renewable Energy Update: https://hubs.li/Q02DZdcN0 ✔️ NYSERDA opens latest solicitation for large-scale, land-based renewable energy ✔️ City of Pasadena, California, unanimously approves $100M, long-term contracts for renewable energy, battery storage ✔️Energy Dept. announces $900M for modular nuclear reactor projects #RenewableEnergy #Solar #Energy

I was really amazed by the 3rd workshop of the Sustainable Energy Accelerator program. The increasing adoption of non-conventional energy sources, such as solar, wind, hydrogen power has significant implications for electricity tariff structures. The operation and maintenance (O&M) of these non-conventional sources must be considered alongside the O&M of conventional sources like thermal and nuclear power plants. The variable nature of non-conventional sources, such as the intermittency of solar and wind power, requires careful planning and management to ensure grid stability and reliability. The cost associated with the integrating, balancing and backing up these non-conventional sources must be accounted for the electricity tariff. Additionally, the maintenance requirements and life cycle cost of non-conventional power generation assets differ significantly from conventional sources, leading to the need for more comprehensive tarrif framework. The electricity tariff differ from countries to countries based on their respective regulations and policies. #SEAImpact #Energytransition #Newtechnologies

This is the root of the challenge with renewables powered by the diurnal cycle (direct solar and indirect solar via wind). The energy isn't when and where you need it, especially in the winter when overcast skies remove direct solar as a resource when energy for heating is needed. Firm generation backup, energy storage, lots more long-distance transmission capacity and demand management are the costs that are often ignored. Space Solar Solves all of that. #sbsp #spacesolar #solar
