1Costs for the advanced nuclear technology reflect an online date of 2022. 2The subsidy component is based on targeted tax credits such as the production or investment tax credit available for some technologies. It only reflects subsidies available in 2020, which include a permanent 10% investment tax credit for
geothermal and solar technologies. EIA models tax credit expiration as follows: new solar thermal and PV plants are eligible to receive a 30% investment tax credit on capital expenditures if placed in service before the end of 2016, and 10%
thereafter. New wind, geothermal, biomass, hydroelectric, and landfill gas plants are eligible to receive either: (1) a $23.0/MWh ($11.0/MWh for technologies other than wind, geothermal and closed-loop biomass) inflation-adjusted production
tax credit over the plant's first ten years of service or (2) a 30% investment tax credit, if they are under construction before the end of 2013. Up to 6 GW of new nuclear plants are eligible to receive an $18/MWh production tax credit if in service
by 2020; nuclear plants shown in this table have an in-service date of 2022. 3Costs are expressed in terms of net AC power available to the grid for the installed capacity. 4As modeled, hydroelectric is assumed to have seasonal storage so that it can be dispatched within a season, but overall operation is limited by resources available by site and season.

Conclusions
Strange enough the major countries continue to produce electricity only from fossil expensive sources. With rapid economic growth and massive urbanization, many cities face the problem of municipal solid waste (MSW) disposal. Undoubtedly using dry MSW to produce electric energy is the cheapest way of generating electricity solving also an environmental and health problem So, the solution to produce renewable electric energy from waste combine 2 huge issues in one sustainable way out.
