Yes, once the general public begins to understand the nature of our predicament. And strictly speaking, water is not necessary for power generation, though it is of course used with common LWRs. High temperature systems can use other heat transfer mediums like CO2 or He. Ambient air cooling systems are known as "dry cooling" within the industry, and will be necessary to use to increase production (water supplies are already under strain).
Global energy production is on the order of 17 terawatts which brings the per capita average to about 2 kW. The US average is over 10 kW. This is quite significant as it affects individual freedom, the quality of food available, affordable goods and services, etc. Encouraging energy use is the primary method for reducing poverty, so of course it is necessary to not only increase the usefulness of energy already delivered (through efficiency), but also to increase the quantity. Just to bring per capita use up to 5 kW by 2050 will require producing about 3 times as much as what we produce today. Considering that in addition to that we must completely eliminate fossil fuel use, quite a formidable challenge awaits us.
There really is no alternative as renewables are not a realistic option for our predicament: we must eliminate fossil fuel usage while drastically reducing the cost of that energy (in terms of energy return over energy invested). Trying to do this with low density sources (renewables) will only promote environmental destruction and continue our dependence upon fossil fuels (estimates for the cost of this kind of infrastructure conservatively runs into the 100s of $trillions and is very likely completely impractical at scale). Current renewable equipment prices are not a true measure of the actual cost in terms of energy, and indicates very little of what happens when the industrial system tries to use renewable energy as a manufacturing base (the cost will drastically rise while the return will plummet).
Truly, the issue is quite complicated and no laughing matter. If it were not for some very poor political decisions made decades ago, we might already have applicable technology available today, but now we must educate the public and then embark upon an aggressive development program to try and minimize the damage while mitigating future risk.
And of course, there is no guarantee that we will avoid catastrophe as the risks we currently face are quite formidable. Nuclear fission only gives civilization its best shot.
