And doing so ignores the not inconsiderable problems of getting the power from the Sahara to where it is wanted in Europe, never mind the USA. (Also many such schemes ignore the fact that solar is only directly available during daylight hours at the panel so one either needs a whole interconnected network of such farms in different time zones, or some way of storing energy for use during panel-night.)

We have high efficiency "DC interconnectors" that you can imagine can replace the existing leviathan fleets of dirty big old oil tankers. And we have multiple different good tech for overnight storage of solar power. The next steps are to work through the infrastructure costs, politics, and the inevitable delaying tactics of the existing dirty old fossils industry. We can can quickly and efficiently go clean, given the political impetus.

Here is another following in the tire tracks of Elon Musk and Tesla: Volvo Cars to go fully electric by 2030 If Sweden can do that, why not the rest of the world?

Here is another following in the tire tracks of Elon Musk and Tesla: If Transport is to go 100% electric, then at 2016 petroleum product usage we need 30 trillion kWh of energy to replace it. An increase of 20% over present day electricity production. Even if plans are in place to increase electricity production rather than replace old dirty stations it takes more than 10 years to get approved, built, commissioned and connected up. |

If Transport is to go 100% electric, then at 2016 petroleum product usage we need 30 trillion kWh of energy to replace it. An increase of 20% over present day electricity production. Which is why we already have for the UK a lot of new electrical capacity that is in the process of being built up, hopefully all to be ready in time. The biggest spoilers are the ridiculously expensive nuclear plans all suffering delays and going badly over budget from a very expensive start in the first place... That sort of money can cleanly rebuild our national grid and double the renewables capacity and still leave cash to spare for storage... The joker in the UK strategy is what might be done with the promise of hydrogen... Whichever way we go, will it all be soon enough? There are multiple threads there to watch!

Is this a good way to go? Chinese £3,200 budget electric car takes on Tesla wrote: A budget electric vehicle (EV) selling in China for $4,500 (£3,200) is now outselling Tesla's more upmarket cars. Could that 'take off' in the USA? 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) |

Interesting, but sadly I doubt that the tiny car would make a substantial impact on the US (or even European) car markets. Simply, it's too small as it has been scaled around the average person in China and not the average European let alone the average American. That said, given the price and inducements reportedly being offered it is hardly a shock that it is outselling Tesla (free road tax, a tenth of the price etc.). Having been in several major Chinese cities I would say anything that reduces the number of ICE engines in use will be a good thing.

Climate change: Jet fuel from waste 'dramatically lowers' emissions A new approach to making jet fuel from food waste has the potential to massively reduce carbon emissions from flying, scientists say. |

https://cleantechnica.com/2021/03/25/all-eyes-on-4-million-diesel-killing-hydrogen-locomotive-in-california/ Hydrogen gets props as a zero emission fuel. When deployed in a fuel cell, it reacts with ambient air to generate electricity. Water is the only byproduct. However, shadowing the tailpipe is a long, dirty tail. Almost all of the hydrogen circulating the globe today is produced from fossil energy, mainly natural gas. |

Announced by the Green Homes Grant scheme to insulate houses axed A much-promoted grants programme to help UK householders insulate their homes is to be scrapped within days.To be fair, I wouldn't fight to save the scheme in the current form. The chumocracy have made a complete horlicks of it, as usual. But to do it this way? I think I smell the smell of a big scoop on the front page of one of the Sunday newspapers. We'll find out in the next hour or so. |

... To be fair, I wouldn't fight to save the scheme in the current form. The chumocracy have made a complete horlicks of it, as usual. But to do it this way?... The biggest effect to go usefully efficiently Green is to break up the presently in force all-too-effective effective house building monopoly that everyone suffers. Those few companies have extremely profitably minimized standards, exploited unskilled labour, and pushed house sales prices to extraordinary heights, all for incredibly badly sloppy build. We also have deliberately (very profitably) restricted supply, and a boom-bust cycle whenever our government panics about the housing supply. Totally, a blight across our landscape, and ever more costly to our planet, that is getting ever more expensive to remediate... But politics, and lobbying, and party donations and all that... Oh what a glorious mess! Nothing short of an overhaul throughout the entire process is required.

For a brief example of what can be done: Britain's electricity system 'greenest ever' over Easter wrote: Great Britain's electricity system was the greenest it had ever been at lunchtime on Easter Bank Holiday Monday, its operator has said.

France moves to ban short-haul domestic flights Lawmakers voted in favour of a bill to end routes where the same journey could be made by train in under two-and-a-half hours.That doesn't quite cover everywhere (Paris - Marseille is just over 3 hours minimum). But it's a lovely run, the bar is open, and the tickets are cheap(-ish). Beats our poxy little HS1 into a cocked hat any day. |

Another positive yet small step?

Here's something that should have been done over a decade ago: Carbon Mapper satellite network to find {pollution} super-emitters wrote: A constellation of satellites will be flown this decade to try to pinpoint significant releases of climate-changing gases, in particular carbon dioxide and methane. Notice how that is being launched by a CHARITY. Was there not a "Carbon Mapper" satellite that was to be launched in the 2000's that was delayed and in effect sabotaged by the then Bush administration?... All a game of how the polluters cannot get 'caught' at their dirt?...

Look up the MOPITT instrument on the NASA Terra satellite. been on orbit since late 1999, still flying. The instrument team is a small group out of Canada, and the Principal Investigator is English I believe (sounds English from his accent but I never asked him directly). Very nice group of people. We have over 20 years of near constant data from this instrument. There are several other missions doing atmospheric pollution research, Aura (launched 2004) also, but unfortunately half of it's instruments have stopped working anymore. Dedicated carbon missions like OCO-2 (launched 2014). and many more. https://climate.nasa.gov/nasa_science/missions/?page=0&per_page=40&order=title+asc&search= no political conspiracy here. things get delayed/sacked for a lot of reasons, that mostly have nothing to do with politics.

Thanks for those. Looks like the one I was thinking of was: Orbiting Carbon Observatory: Launch Failure That had been delayed multiple times and was in the midst of: Scientists Say Bush Stifles Science... wrote: In his final State of the Union address, President George W. Bush devoted several lines to science and technology topics. He called for research and funding to reduce oil dependency and reverse the growth of greenhouse gases.. Climate Change Research Distorted and Suppressed wrote: ... In September 2002, the [Bush] administration removed a section on climate change from the Environmental Protection Agency’s (EPA) annual air pollution report, even though the climate issue had been discussed in the report in each of the preceding five years... The worst of times: Bush's environmental legacy examined wrote: ... see the Bush years as a concerted assault, from the administration's undermining of the science on climate change to its dismantling of environmental safeguards to its support for mining and oil interests. ISTR that there were various games at play to defund (or 'deregulate') anything and everything that showed the coal, oil and gas industries in any sort of bad light...
