Renewable Energy Sources

Tier I alternative energy sources:

1. Solar photovoltaic and solar thermal energy.
2. Wind power.
3. Low-impact hydropower.
4. Geothermal Energy.
5. Biologically derived methane gas.
6. Generation of electricity utilizing by-products of the pulping process and wood manufacturing process including bark, wood chips, sawdust and lignin in spent pulping liquors. In-state resources of this type are now considered Tier I.
7. Biomass Energy.
8. Coal mine methane.

Tier II alternative energy sources:

1. Waste coal.
2. Distributed generation systems.
3. Demand-side management.
4. Large-scale hydropower (including pumped storage).
5. Municipal solid waste.
6. Generation of electricity utilizing by-products of the pulping process and wood manufacturing process including bark, wood chips, sawdust and lignin in spent pulping liquors.
7. Integrated combined coal gasification technology.
