Japan did a lot for their solar PV market, much like they did for hybrids, with subsidies for the hardware, and contracts with power companies for buy-backs. People are switching away from gas/kerosine heating and water heating, and going to electric. Pretty hard to go anywhere and not see panels on roofs, or little mini-panel farms where rice fields used to be. (Compare that with back home: I can count on one hand the number of houses I see with PV on the roof.)Carlos_C wrote: ↑Tue Jan 14, 2020 1:46 pmFukishima had some bad design
there were two other reactors hit by the Tsunami on Onagawa was even closer to the epicentre
If we go on mass to electric vehicles and start heating our homes with electric rather than gas .......renewables will not atm be able to cope with that demand and we either have to stay on fossil fuels or ramp up nuclear
The Onagawa Nuclear Power Plant (女川原子力発電所, Onagawa (About this soundpronunciation) genshiryoku hatsudensho, Onagawa NPP) is a nuclear power plant located on a 1,730,000 m2 (432 acres) site in Onagawa in the Oshika District and Ishinomaki city, Miyagi Prefecture, Japan. It is managed by the Tohoku Electric Power Company. It was the most quickly constructed nuclear power plant in the world.
All the reactors were constructed by Toshiba. The Onagawa-3 unit was used as a prototype for the Higashidori Nuclear Power Plant.
The plant was shut down after the 2011 Tōhoku earthquake and tsunami. The Onagawa nuclear power plant was the closest nuclear power plant to the epicenter, and facing the Pacific Ocean on Japan's north-east coast, experienced very high levels of ground shaking – among the strongest of any plant affected by the earthquake – and some flooding from the tsunami that followed. All three reactors at the power plant successfully withstood the earthquake and tsunami without incident.
Following an IAEA inspection in 2012, the agency stated that "The structural elements of the NPS (nuclear power station) were remarkably undamaged given the magnitude of ground motion experienced and the duration and size of this great earthquake,". More recently, Tohoku Electric reported that the third floor of No. 2 reactor building lost about 70% of its structural rigidity and the first floors lost 25%, compared to when they were built, and was planning to reinforce the structures for increased quake resistance. In 2013 the station operators sent an application request to restart unit 2 at Onagawa to the Japanese Nuclear Regulatory Agency.
Great! Just make sure that the population is falling as food production land is being taken up for solar power generation. That should be the first consideration.
Even in a 100% solar powered world also with heat, industry and mobility. The area needed for solar power plants is not even 1% so is not in competition with land needed for food production. There are also first plants with combined PV and agriculture and some crops even profit from the partial shading of panels.
Actual solar panels and plants are recyclable and it is done in practice, already seen it in big plants as in Europe we start to have a relevant number of return. Dismounting a PV plant gives a slight positive output as the recycling of valuable material as Cu, Al, Ar, Si etc. pays back the effort for removal. In more than 95 % of the panes there are no relevant toxic materials apart from a small part of Pb which can be extracted aswell during recycling. Just the US company "First Solar" uses the toxic cadmium, but in a stable untoxic combination and they have an own recycling process which I would expect to work well, as the have to recycle a lot since more than 10 years with returns around 2%.
As said I don't know the situation in the "Country of Fracking". In the over 10 countries in 2 continents I have seen many 100 of PV plants:Matteo V wrote: ↑Tue Jan 14, 2020 7:14 pmNo wait, let's first investigate the environmental impact of solar farms being installed on land that was once green vegetation. From what I have seen of solar farms, the ground is covered with crushed rock and then sprayed with soil sterilant chemicals to prevent weeds and trees from growing up in the area. All of this land that is taking up by solar farms is essentially sterile and devoid of life.
Not expert for that, but as far I know wind turbines are often shut of not for single birds but for swarm of birds.
Yery cool and indeed the best way, have done it myself in the past but now more distant to the lake. But also know guys doing it even with windsurf equipment. Actually tring to go by bike again this year.
It ain't an electric car if I use a gasoline generator to charge it. And that's the whole problem with Renewables and Electric vehicles. And I am right on topic with this one! A percentage of the electricity put into your battery is always going to be from NOT solar or NOT wind-generated power. This leaves nuclear hydroelectric or fossil fuels such as natural gas and coal to produce the electricity you use when driving the vehicle.
