For LFTR to produce 1GW of power, enough for a small city, an equivalent of around 3000-4000 to 4GW of wind power turbines, and large distances of powerlines and upgrades are needed. With LFTRs inherent safety, large obtrusive containment vessels and walls are un-necessary. LFTR operates at high temperatures and drive air turbines that are far smaller and lighter than steam turbines. Thus, a 1GW LFTR requires far less construction materials than conventional nuclear reactors. Given its compact size, LFTR would also use at least 4 to 5 times fewer materials in construction than wind or solar power.
Wind power while classed as renewable, every tonne of steel 
or aluminium is not. Aluminium must be smelted, purified, alloyed, rolled and transported at great environmental cost. Wind power uses a range of material such as concrete, plastics, fibreglass, and electronics which further question its green credentials. Green technology rebuttals focus upon on the benefits from investing in green technology, and its economic benefits by creating ‘green jobs’. This belief is based more fiction than fact as, as many of these jobs are ‘artificial’ jobs as they are creating inefficient products and services that are not cost competitive with other sources of power.
