<p>The apparent volatility of electricity generation from a single wind turbine is negligible, because what counts is the wind and PV output over large areas. Due to regular weather fronts, electricity output from wind and PV in Europe is surprisingly stable; when there is less sunshine, there is more wind.
In 2025, for example, the weekly electricity output from wind and solar PV was 14.0 TWh, with no week falling below 10.5 TWh. If more wind power were installed in Eastern Europe, the curves would flatten out even further.<p><a href="https://www.energy-charts.info/charts/energy/chart.htm?l=de&c=EU&interval=week&legendItems=lw3w1&week=-1&partsum=0&year=2025" rel="nofollow">https://www.energy-charts.info/charts/energy/chart.htm?l=de&...</a></p>

<p>A single wind turbine or a single PV module obviously provides only variable amounts of electricity. However, this is not the case for many PV modules and wind turbines spread across the entire continent. Wind and PV complement each other very well in Europe because of regular weather fronts; when there is little wind, there is more sunshine.<p><a href="https://www.energy-charts.info/charts/energy/chart.htm?l=de&c=EU&interval=week&legendItems=lw3w1&week=-1&partsum=0&year=2026" rel="nofollow">https://www.energy-charts.info/charts/energy/chart.htm?l=de&...</a><p>In Europe, the average weekly electricity generation in 2025 was 14.0 TWh, and no week fell below 10.2 TWh.
In 2026, the average output was about 15.5 TWh, and so far, no week has fallen below 12.5 TWh.<p>Of course, batteries are needed for short-term storage, but with the creation of excess capacity in wind and solar power, the troughs below the load curve become narrower and shallower, drastically reducing the need for storage.</p>

<p>Not really. Nuclear power requires massive subsidies. In Germany, the "De Height" wind farm was completed in August. Sixty-four 15-MW turbines generate about 4 TWh of electricity annually, which is sold entirely on the open market without any EEG funding.<p>The market for baseload electricity has disappeared in Germany, as renewables push the residual load to zero or below for almost the entire year:<p><a href="https://www.energy-charts.info/charts/power/chart.htm?c=DE&legendItems=myi&interval=year" rel="nofollow">https://www.energy-charts.info/charts/power/chart.htm?c=DE&l...</a><p>The base load is an imaginary line passing through the troughs of the residual load curve.</p>

<p>Here is an analysis from Germany: Quarter-hourly spot prices compared to the share of renewable energy generation in total generation. A higher share of renewables puts massive downward pressure on the spot market electricity price.<p><a href="https://www.energy-charts.info/charts/price_scatter/chart.htm?l=en&c=DE&bzn=DE-LU&renewable_share_of_generation=1" rel="nofollow">https://www.energy-charts.info/charts/price_scatter/chart.ht...</a><p>Since price elasticity for electricity is very high, the market cap decreases by approximately €150,000 for every additional GWh of renewable energy production. A single additional offshore wind turbine with an annual output of 60 GWh reduces the combined revenue of all electricity producers by about €9 million per year that it is in operation.<p>Blocking wind power and solar projects only serves to secure the profits of monopolists and oligopolists in the electricity market, but causes massive harm to the economy.</p>

<p>Nuclear power has been killed off by economic forces; there’s no turning back. 
Solar and wind power generate cheap electricity in abundance, and midday electricity prices in Europe regularly dip into negative territory (as low as minus €500 (sic!) on May 1!).<p>Modern grids do not require high-risk investments in ultra-inert baseload power that ultimately fails to find a market; instead, they require low-risk investments in highly flexible power sources, such as batteries or pumped-storage facilities and transmission upgrades, that can capture surplus electricity at low cost (sometimes negativ) and sell it hours later at favorable prices.<p>The 2036 electricity futures price for Germany is €70/MWh. The break-even point for France’s EDF for old nuclear power plants that had long since been written off financially was at roughly the same level in 2020. Due to rising labor costs, their break-even point is now significantly higher. There were solid economic reasons why EDF was recently nationalized 100%. New nuclear power plant construction in France is a foreseeable economic disaster. Private investors would have fled long ago.</p>

<p>MS Access can use DBF files almost as if they were standard Access tables. This was particularly useful when working with ESRI Shapefiles, as it allowed the DBF files to be edited in Access and the changes to be viewed directly in ArcGIS. When editing maps, Access was often more convenient than the ESRI Editor.</p>

<p>Wind and solar power are remarkably stable in Europe. Last year, the average weekly electricity output was 14.0TWh; not a single week fell below 10.5 TWh.<p>Weather fronts move across the continent on a very regular basis; when the wind dies down, the sun shines more.</p>

<p>Nuclear energy is pure economic madness in a context where wind and solar power are generating a surplus of electricity. Today, May 1, electricity prices in Europe are in some cases at the technical minimum of minus €500/MWh.<p>Thermal power generation, which is difficult to control, is completely unnecessary in an environment where we have negative electricity prices practically every day from March to October. In Europe, we need rapidly controllable energy sources—obviously more storage capacity.<p>Due to the many hours during which electricity prices are close to zero, the economically viable full-load hours of a nuclear power plant are reduced to barely 3,000 hours per year, effectively tripling the real levelized cost of electricity (LOCE). In addition to the high costs of nuclear power plants, there is also the enormous expense incurred by the government for military and police security at the facilities.<p>Since the government prioritizes nuclear power, this leads to heavily manipulated electricity prices, with homeowners with solar panels being among the biggest losers, as they are required to feed electricity into the grid but are effectively paid the full negative prices (usually via weighted average pricing methods)</p>
