But fusion power plants needs to breed and separare tritium, prevent excessive tritium losses in the first wall. The plasma-facing materials in tokamak are subject to very harsh conditions, mutch harder conditions then reactor walls in a fission power plant.

For example Greenpeace had it roots in the oposition to nuclear weapon testing at the end of 1960s.

"They introduced many innovations as they built their designs, including bell crank suspensions, as pioneers in amphibious tanks, and the use of diesel engines that were less likely to catch fire compared with gasoline tank engines that were being used at the time."

"Balcony solar power systems are generally permitted up to a capacity of 800 watts, with this limit referring to the maximum inverter output. Consumers must register their systems in the Federal Network Agency's market master data register. This registration is important to maintain an overview of installed solar energy and to ensure compliance with legal requirements."

" In many EU countries, balcony power plants are already permitted with higher power limits. Countries like the Netherlands , France , and Italy allow balcony power plants with a capacity of up to 2000 watts or even more. These countries have recognized that the integration of mini-PV systems plays a crucial role in achieving their climate goals. The Netherlands, in particular, actively promotes balcony power plants through tax breaks and financial incentives.

Another example is Austria , where the power limits are less strict, and systems with up to 800 watts per module are permitted. Consumers can install multiple modules, each with up to 800 watts. The total output of the solar system is therefore not as strictly limited as in Germany. For example, two 800-watt modules could be used, resulting in a potential total output of 1600 watts . In combination with a suitable inverter, more electricity could be used or fed into the grid. Here, too, simplified registration procedures and regional subsidies support the use of solar power. "

The Germans manage their electric grid very well, the last major electric blackout in Germany was in 2006. (More than 15 million clients of the Union for the Co-ordination of Transmission of Electricity (UCTE) did not have access to electricity for about two hours on this date.)

Those links and the associated large costs, were not necessary in the past. I would like to note that, the amounts of electricity produced each year in Europe didn't change much for the past 40 years.

" In late 1983, in an effort to bootstrap the GNU operating system, Richard Stallman asked Andrew S. Tanenbaum, the author of the Amsterdam Compiler Kit (also known as the Free University Compiler Kit), for permission to use that software for GNU. When Tanenbaum advised him that the compiler itself was not free, but rather only the university, Stallman decided to work on a different compiler. "

"Increased rates of component life consumption due to thermal fatigue, mechanical fatigue and wear caused by differential thermal expansion comprise the bulking of cycling (costs)," according to the International Energy Agency's Coal Industry Advisory Board.

"Every time a power plant is turned on and off, the boiler, steam lines, turbine and auxiliary components go through unavoidably large thermal and pressure stresses," the National Renewable Energy Laboratory (NREL) wrote in a report on cycling costs published in April 2012.
