Yes, it is a state. A unique state. You do hear about Rhode Island in the news, any time there's a mafia arrest, or large-scale world disaster, like a fire out West, which will invariably be mentioned in terms of number of Rhode Islands affected.
Existing types of fossil plants have a capital cost about $1-2 Billion/GW and new nuclear plants are estimated to cost about $2-5 Billion/GW, depending on the laws of the country in which the plant is built.his translates into an average of about $25,000 per Megawatt-hour and $25 Million per Gigawatt-hour. A storage plant that needs to store 26 Gigawatt-hours (just 1 day's power supply) would thus cost about 650 Million dollars to build (estimated range from $260 Million to $1.1 Billion dollars).
Single stage, 80% efficient gas furnaces typically cost $2,000 or higher, moving up to a 90% efficiency range of this same type can cost $3,000. To move into the 95% efficiency range with a multi-stage or modulating furnace that feature variable speed blowers can cost $5,000 to $7,500.ith the ever increasing costs of electricity it is the most expensive furnace to operate on this list. The typical price to replace an electric furnace ranges from $1,000 to $1,500. These furnaces can last about 25 to 30 years and the efficiency ranges between 80 to 90 percent.
