comment Why is the proposed Hinkley Point nuclear power plant so expensive?
@manu190466 the difference between the two prices is the estimated financing cost: \$24bn is the estimated overnight capital cost;\$35bn is the estimated fully-financed built cost.

comment Why is the proposed Hinkley Point nuclear power plant so expensive?
@sammygerbil I'm not sure efficiency has improved, has it? On a thermal basis it's still only ~33%; and on a fuel-basis (assuming once-through) it's still only ~2%

I'm voting to close this question as off-topic because it's primarily about economics and politics, with some engineering. And no physics.

comment which is efficient on solar electricity by photo voltaic or thermal
It's a new technology, still being developed. People will continue to invest as long as it shows the potential to be economically viable. It's very inefficient only at small scale: at larger scale (10s-100s of megawatts) it's efficient enough to be potentially economically viable.
