Since 2014, Costa Rica has been producing more than 98% of its electricity from hydro, geothermal, solar and wind.
Here are some inspiring countries that are using clever combinations of renewable resources and efficient, targeted policies to drive down their emissions.Sweden. In 2012 Sweden reached their target of 50% renewable energy 8 years ahead of schedule. ...Costa Rica. ...Scotland. ...Iceland. ...Germany. ...Uruguay. ...Denmark. ...China.
And the list has Grown we can include USA AND Many Eu countries.
So renewable energy is just not a Labour pipe dream it can be achieved in this country

 - have you a working example of this scheme in mind? I know flywheels are already storing energy from windmills if that is what you are asking. have you a link to this solution for when there is no wind?.. |

Excess energy can be stored, not sure if flywheels is the best option, pump storage and batteries are also options but realistically a background of nuclear or coal fired is always going to be a necessity to eke out the stored energy. Dinorwic pump storage is huge and was expensive yet is only small scale in terms of the needs of the grid. It was only there to iron out peak demands over short time periods of a few hours. Flywheels are currently being used Sandy as a method. If there are other methods then great. Batteries wouldn't work on the National grid though. As for nuclear, that's fine. I have no problem with building nuclear plants. The major issues though by only going nuclear is cost and time. Windfarms take a year to set up and get operating, nuclear plants take decades and a huge investment cost. Starmer wants the UK to be enery self sufficient by 2030 and that is realistically possible with renewables. The GPO using flywheel storage way back in the 50s if I recall. The biggest problem seems to be the bearings and even with magnetic bearings the energy stored seems to degrade quite badly. I have some solar panels and a wind turbine but storage is my main problem and in the summer I have to do most power tool jobs when the sun is shining. I have looked at water, as I have a hill behind, but volume is the problem and as far as batteries are concerned I would need at least two dozen of the deep cycle lithium to be any real use in the winter. On a nationwide scale I see these problems not as insurmountable but challenging. |

I was hoping that this was going to be a system that was in use commercially - but it seems to be just an idea that scientists are researching. At least with Nuclear power we know it works. |

How do countries like costa Rica that depends upon renewable energy to pwer it electricity supply.
They must have some source of power saving device.

It is an idea that is commercially used. Fly wheels work and been used for centuries. And they are building flywheel storage in Scotland anyway and that is before GB energy has been set up. At this point I am arguing with someone who doesn't want to accept that maybe Labour are onto something here and that wind can make the UK energy sufficient by 2030 at a low cost and nuclear by 2050 at a huge cost. |

On a nationwide scale I see these problems not as insurmountable but challenging. I'm sure our engineers can work it out Sandy. Magnetic Flywheels are very good actually as there isn't much friction but like everything it may need maintenance from time to time and in terms of the national grid, it is just to make sure we have energy when the wind doesn't blow so it can afford some degradation given it is meant to be for short term storage. Also, bit of trivia... do you know that on windy days the national grid has to shut windfarms down because it doesn't have the capacity to store the electricity? Seems to me flywheels are long overdue. |

They have hot water geysers that provides most of their domestic heating. |

Excess energy can be stored in flywheels. Dinorwic pump storage is huge and was expensive yet is only small scale in terms of the needs of the grid. It was only there to iron out peak demands over short time periods of a few hours. It worked though, didn’t it. My main concern regarding storage of excess renewable energy is I’m not entirely convinced there is that much. On a blazing hot day with not a cloud in the sky the most you get from solar energy hitting the ground in southern Britain is 650 watts per square metre at high noon, 450 in the morning. Those are the values I was paid to calculate when a newly qualified graduate scientist in the summer of 1979. |

100 million sounds good but how much money was lost to people whose livelihoods have been adversely affected by the charges and to businesses in the tourist and hospitality trades as a result of visitors not traveling to London anymore? Sadiq Khan is turning London into the Ghost town capital of the world Sadiq Khan's £12.50-a-day ULEZ made TfL nearly £100MILLION in under a year - as Mayor of London presses ahead to expand the zone to cover the entire capital next year TfL has raked in an extra £93m since ULEZ expansion came into effect last year ULEZ made 18 times larger in October last year - with levy charging £12.50 a day TfL said it uses the cash to 'reinvest' into public transport, walking and cycling Mayor vowed to press on with expansion, despite survey revealing unpopularity www.dailymail.co.uk/news/article-11339613/ULEZ-Sadiq-Khans-12-50-day-levy-TfL-nearly-100m-Mayor-presses-ahead-expand-zone.htmlThere is growing opposition to Khans plan the expand ULEZ from " My London" In a letter to the to the Mayor of London Sadiq Khan, Harrow ’s leadership, in conjunction with Hillingdon, Bexley, and Bromley councils, said it is “strongly opposed” to the plans, citing the “adverse effects” it will have on residents, businesses, and visitors. The council, which has opposed the scheme since its announcement last year, is “not satisfied with the justification” for the expansion. The letter said: “Until we have seen compelling evidence to the contrary, it remains our position that this scheme will not translate successfully to outer London and the negative impact to local households and economies will far outweigh the negligible air quality benefits.” I hope more outer London Councils do the same. |
