How to achieve a net-zero economy by 2050

Today, about 80% of our energy comes from fossil fuels. To limit global warming to below 2°C and as close as possible to 1.5°C, the world must reduce greenhouse gas emissions to net-zero by mid-century.

A net-zero economy by mid-century is technically and economically feasible, and is built on abundant, cheap zero-carbon electricity. Transitioning to electricity as the main source of final energy represents the cheapest and most efficient way to decarbonise the economy. Direct electrification will be key to decarbonising many sectors of the economy, including road transport and building heating.

If we are talking about the UK, one huge hurdle is the argument that countries like Pakistan, India, China, Russia and USA are by far exceeding UK emissions and continuing to add C02 into the global atmosphere when the UK only emits shy of 1% of the global output, so why bother? After all it will initially cost huge amounts of upheaval and financial harm and any jobs created are not wealth creators but built on debt not growth.

gouging out acres and acres of land for windmills and solar is not the answer do not get me wrong wind and solar have their place, but solar and wind farms take up a lot of land . what about small nuclear plants clean burning syn gas those do not take up as much room.

Just nonsense! Your video seems to suggest that renewable electrical energy will achieve net zero by 2050, when electrical energy only accounts for 20% of the global energy demand. And just where are we supposed to find the resources to achieve complete renewable electrical energy? Well, they are currently in the ground, can we use renewable electrical energy to dig them up, process them, transport them, manufacture them, distribute them, install them? I think not. The hubris involved in the title of your video, 'How to achieve a net-zero economy by 2050' and its 2:43 long! If only it were that simple.
