A small home system can be installed for as little as $25k dollars if you do the work yourself. Larger homes and small companies would be proportionally more expensive. Johnson Controls spent a million dollars to provide some power for their lights in Milwaukee recently. Power completely from solar is prohibitively expensive in many cases.
The average cost of building a hydro power plant on the Columbia river is 559,220,000.

solar power from a concentrated solar power plant costs the same as electric from a fossil fuel pant. if you install home photovoltaic solar panels, it will cost up to $25,000. after installation, there is little maintenance and the panels will last over 30 years.
Nuclear is about the same as fossil fuel in total costs, but more expensive to build the plant. Solar and wind power are more expensive and have to be subsidised to make them economic for power companies to use

The cost to build a geothermal power plant can vary depending on factors such as location, size, and technology used. Generally, the estimated cost for a medium-sized geothermal power plant is around $2-7 million per megawatt. However, these costs can be significantly higher for larger or more complex projects.
Solar power only requires initial investment. The cost of setting up solar panels is high, but after that, the cost of maintenance is negligible.
