What is the most feasible immediate option for addressing global energy issues? 

A)  Increase efforts to develop breeder nuclear fission and nuclear fusion. 
B)  Build more and better conventional nuclear power plants. 
C)  Find and burn more forms of oil, natural gas, and coal. 
D)  Reduce unnecessary energy waste by improving energy efficiency.

The most feasible immediate option for addressing global energy issues is to reduce unnecessary energy waste by improving energy efficiency. This can be done by using energy-efficient appliances, improving insulation, reducing transportation emissions, and promoting energy conservation practices. This option is feasible because it does not require new technology or infrastructure and has the potential to produce significant energy savings and cost reductions in the short term. Additionally, improving energy efficiency is a sustainable solution that can help reduce global energy demand and greenhouse gas emissions.
