Is nuclear power use expected to grow more in the economically developed or developing nations of the world, and why?
Developing; due to its cost and accessibility, nuclear power will receive substantial investments in growing economies.
Developing; advances in safety technology has made nuclear energy more accessible to poorer nations.
Developed; cost and access to nuclear power limits its use to the wealthier nations.
Developed; advances in safety technology has made nuclear energy more accessible to all nations.
Is renewable energy use expected to grow more in the economically developed or developing nations of the world, and why?
Developing; alternatives such as passive solar and biofuel are expensive so cost would limit their use in these regions.
Developing; low cost renewables like passive solar and biomass are expected to support the growing infrastructure in these regions.
Developed; expensive alternatives such as solar and biofuel are expected to be limited to only the wealthiest countries.
Developed; low cost renewables like solar and biomass are expected to support the growing infrastructure in these regions.
Is fossil fuel use expected to grow more in the economically developed or developing nations of the world, and why?
Developing; rapidly growing populations and living standards will lead to more use of conventional energy resources.
Developing; declining populations will make fossil fuel use more affordable for these young nations.
Developed; rapid population growth and wealth growth will help these regions access this new energy resource.
Developed; rapid population growth and wealth growth will help these regions access this new energy resource.
