Question

mateos parents are thinking about investing money to help develop a new fusion power plant. which issue is most important to consider before making the investment?
fusion has never been controlled, so how have they succeeded in doing it?
the fuel is quite limited, so have they discovered a more common fuel?
fusion has been generating electricity for decades, so why build another fusion power plant?
fusion requires high temperatures and pressures, so how have they reduced the energy cost for it?

Explanation:

Fusion power plants require high - temperature and high - pressure conditions which are energy - intensive. Reducing energy costs is crucial for economic viability of investment. Option 1 is incorrect as controlled fusion research is ongoing. Option 2 is wrong since fusion fuels like deuterium are abundant. Option 3 is inaccurate as fusion has not been generating electricity on a large - scale for decades.

Answer:

Fusion requires high temperatures and pressures, so how have they reduced the energy cost for it?
