I think you're vastly underestimating what it means to have (virtually) unlimited energy. Things that we are not doing now because it's not economically viable, become viable. Water filtration for drinkable water is huge and also happens to be one of the main problems in the world. That problem becomes more approachable when you have an excess of energy at your disposal. Recycling materials is also heavily constrained by energy costs. With so much energy available you can employ recycling techniques that are not viable right now and/or do it at a larger scale. There are also huge reductions possible when you have abundant energy. Take out costs associated with driving your car, or the cost of cleaning up ongoing pollution, or the costs of extracting energy from scarce resources. Those could all be dramatically reduced once abundant energy becomes a reality. It will be impactful for people who are not rich (99% of the planet), not having to pay huge chunks of income for energy. After rent costs, the biggest part of my living costs come from energy production (elec, gas, water etc). Abundant energy also makes a more distributed form of general production more viable. The more communities become self reliant, the less vulnerable the world becomes to localized disasters (political and environmental) and the stronger our ability to help out communities that are suffering. All the costs we are making (money & environmental) for the purpose of transporting goods and resources around the world can be scaled back. Think about this for a minute, if you have access to cheap abundant energy, you have some source of water and the technology to filter it than you have all the basic necessities to supply basic survival needs to a community. That is huge.
