And waves across an ocean can travel for thousands of miles... It is very rare to have no waves crashing upon a seashore. And as for all renewables, you always have a mix of sources to guarantee a diverse supply.

Not all waves are generated by the action of wind over water, some are the result of tidal motion of the sea over the sea bed, turbulence due to the inflow of rivers. And as Martin says these waves can travel for trans-oceanic distances. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

The most significant place in the UK is the pentland firth So far most trials there have failed because the tidal power is so strong the generating devices have broken their moorings. |

tidal action is not waves. waves don't transport water, tides do |

Some may not like this, but... This Tiny Modular Nuclear Reactor Just Got the Green Light From U.S. Regulators. In a major step forward for the burgeoning modular nuclear reactor movement, the U.S. Nuclear Regulatory Commission (NRC) approved all but the final formalities on a tiny reactor design put forth by industry leader NuScale. The July 29 announcement comes after six years of steady work toward regulatory approval.... |

Finally Canberra is leading the way forward. No new gas connections for ACT homes and businesses from 2023 under plan to phase out fossil fuels. Now if they hand out some of that ultra white roof paint to cover up those dark heat absorbing rooves and turn them into reflectors that would be good too. |

Seeing as our last government sat on their coal with gas 2 businesses combined to start cutting the ties. A 'graphite battery' in Wodonga will be Australia's first commercial thermal energy storage. When Finland recently unveiled the world's first "sand battery", there was speculation that Australian manufacturers would soon be rolling out their own versions, as they looked to burn less gas.Now if that little system can cut gas use by 20% using renewable electricity (as claimed) then it wouldn't be hard to scale gas out altogether there. ...The time it takes for TES units to pay for themselves through gas savings depended on where a business was getting its electricity, Mr Zaal said.And that has to be a plus on top. |

One small step for the USA. One Giant Leap for saving our only one planet?... CNN News - Al Gore predicts impact of Democrats' massive climate bill wrote: 14 Aug 2022 - Former Vice President Al Gore discusses the massive healthcare and climate bill passed by Democrats that will soon be signed by President Biden.

Uruguay goes 100% renewables powered for their entire country. They even export completely clean green electricity to their neighboring countries. ... All for a lower cost than that for using dirty old fossil fuel. So... Why the negative title for this report?... Uruguay's price for using almost 100% renewable energy | DW News ... Is the final skewed line in that report inserted in there so as to confuse the real world circumstances, as explained by this comment? https://www.youtube.com/channel/UCvPzhsxmD6hT_NllNv1XpSw wrote: It doesn't matter that the cost of producing renewables are lower, because THE PRICE is set by speculations in "free market". That's why they are happy to export their electricity to Brazil and Argentina. A solution would be to set two parallel prices for local users and export, but that would lead to a potential trade war. Way to go clean! All on our only one planet, Martin See new freedom: Mageia Linux Take a look for yourself: Linux Format The Future is what We all make IT (GPLv3) |

No matter what your spin is, the truth of the matter is that 'renewable energy' all relies on the same old fossil fuels that have gotten us this far. Where do you think all the energy came from to make their plastics and build their batteries? And what are they going to do with them when they reach their end of life? California ALREADY does not know what to do with all of their expired solar panels. Nothing exists without the energy of the sun stored via the petroleum in the ground. Can we do better? Yes, but it will take years more than the greenies will currently accept as possible. The 'greenhouse effect' is already in a steady motion that will not be affected by anything that 'environmentalists' can or will do. It is already in motion and cannot be stopped. So just sit back and enjoy the warming. "Time is simply the mechanism that keeps everything from happening all at once." |

https://factcheck.afp.com/doc.afp.com.327A429 "A 2017 study published in the scientific journal Nature Energy calculated that one gigawatt hour of solar electricity produces five tonnes of greenhouse gases, compared to 820 tonnes for a coal-fired power plant." This is inclusive of the total energy requirement to manufacture and transport solar panels. "The European Environment Agency says around 90 percent of the mass of the wind turbines can be recycled" "Research cited by the EPA and International Council on Clean Transportation (ICCT) also shows that electric vehicles make less planet-warming emissions over their life cycles than gasoline cars." ""In any case, it's clear that the social and environmental impact of global warming is catastrophic, at a different scale than the mining of battery raw materials, and that battery electric vehicles have a much lower global warming impact than combustion engine cars," "According to the European Environment Agency, 95 percent of the materials in solar panels can be recycled." https://www.newscientist.com/lastword/mg24332461-400-what-is-the-carbon-payback-period-for-a-wind-turbine/ "In 2006, turbine manufacturer Vestas studied the carbon payback period for various turbines. This took into account extraction and manufacturing of raw materials, production of the turbines, their transport, erection, operation, maintenance, dismantling and disposal, and the same for their foundation and the transmission grid. The figure was between seven and nine months, depending on the type of turbine. Other analyses have come up with similar figures." Personally, I am more concerned about running out of fossil fuel... if alternatives buy humanity enough time that some long-term solutions in development can come online (ie thorium or breeder nuclear, fusion) so much the better. |

"The European Environment Agency says around 90 percent of the mass of the wind turbines can be recycled" "Can be" is not will be, or is economic, or carbon reducing and until all three are assured it is just more hot air warming the planet. Get studies on what is happening now, not what best practice should be! |

I'm more interested in the 5 - 10% that cannot be recycled. My gut reaction that the majority is the structure and mechanical parts and the parts, that so far cannot be recycled, are at the center of the electrical generation equipment that contain the rare earths and other minerals that are in short supply and are all difficult and dirty to mine and process. edit] Did a little more digging. Suspect those 90 - 95% numbers are questionable as the blades are about 15% of the structures and they are made from glass or carbon fibres that cannot be recycled and go into land fill. Also in that bad news the blades when produced have an expected life of 25 years, BUT are often replaced after 10 - 15 years for more efficient blades. https://www.azocleantech.com/article.aspx?ArticleID=1209 |

Actually there are a few alternative things that can be done with the blades. Engineers are building bridges with recycled wind turbine blades. Can We Repurpose Old Wind Turbine Blades? And in the end. What happens to all the old wind turbines? |

Hi-tech glass fibre, and other fibre reinforces polymers are being recycled into a variety of lower grade polymer reinforcement materials. Wiggo points to bridges, but use is also being found in road surfaces, low-end cement, railway sleepers (railroad ties), garden furniture are also using these difficult to recycle materials. In some cases the recycling is being inhibited by the companies and authorities doing the first stages (collection and sorting) just can't be bothered.

Germany opens a passengers rail line with hydrogen-fueled trains Fourteen hydrogen trains powered by fuel cell propulsion will exclusively run on the route in Bremervörde, Lower Saxony. The 93 million euro ($92.3 million) deal has been struck by state subsidiary Landesnahverkehrsgesellschaft Niedersachsen (LVNG), the owners of the railway, and Alstom, builders of the Coradia iLint trains. The Elbe-Weser Railways and Transport Company (EVB), which will operate the trains, and gas and engineering company Linde, are also part of the project. Now wouldn't it be ironic given Germany's recent fuel issues if the hydrogen was made from natural gas, oil, coal, or water electrolysis using coal-generated electricity. :^p Hydrogen is of course only an intermediary. |
