Fusion energy is NOT feasible.

At least not currently. It's too resource intensive for not enough energy, and that will be the case for a very long time. Right now the next step for energy is to focus on renewables. Even when fusion is actually feasible, it's not unlimited energy, it's a lot of energy sure but the difference between a lot of energy and legitimately infinite energy is extreme. Even if it were infinite energy, a major problem will be the transport and storage of energy, which due to the slow progress of battery technologies is not something that will be fixed anytime soon. Fusion energy is a nice concept sure, but it's just not realistic for a long long time.
