UAE is planning to generate half of its electrical energy by 2050 from solar and nuclear sources, targeting 44% renewables, 38% gas, 12% clean coal, and 6% nuclear energy sources. [14] The UAE intends to introduce electrification into the vehicle park. By 2030, the UAE wants to have 40.000 electric cars on its roads. [15]
The "subject of labor" refers to natural resources and raw materials, including land. The "instruments of labor" are tools, in the broadest sense.
