Relying completely on renewables for electricity; two major concerns remain to be addressed
According to the statistics published by those who analyse the statistics of the National Grid, for the first time, the electricity generated by wind power amounted to more than 50% of the total needed in the United Kingdom on Boxing Day last year. The rapidly-growing renewable energy sector went past the milestone, thanks to Storm Bella that brought in sustained winds with gusts up to 100 miles per hour, while hitting most part of the British Isles. Although it is encouraging to note the achievement, the fact that it’s the random wind speed, which determined the above goal, raises a concern about our long term dependence on renewables without something to fall back on, - on a ‘rainy day’, of course. For instance, in September last year, according to a report, electricity system operator was forced to increase the use of gas-powered power plants by 20% in order to compensate for a slump in electricity generation by renewables. The low wind speed was a major factor for the dec
