Here is a link to this recent debate on the UK Energy Bill:
Of particular interest is the contribution by Lord Moylan. Here is a short exerpt:
"Net zero is not an energy strategy but a constraint on how we might achieve our energy strategy. Nobody seriously thinks that the UK’s commitment to achieve net zero by 2050 will have any significant effect on the heating of the planet, since we produce only 1% of global emissions. At best, it is setting an example to the world; its practical effect will be very small indeed. The core strategy for this Government has to remain abundant and affordable energy for the UK."
"One of the things the Bill does is encourage investment in wind power. Despite claims that the cost of wind power is constantly falling, that is simply not true. Although it has fallen from its early days, it is ceasing to fall; the fall is declining as a result of the maturity of the industry, as you would expect with any industry that matures. But even if the marginal cost of wind power can be brought down to something close to zero—in other words, that it is similar to nuclear power in that regard—none the less, the capital costs required would still require subsidies, in addition to the feed-in tariff, and these are very large indeed when it comes to offshore wind.
