30. Energy Mix
There is a wide variety of renewable energy technologies that are producing commercial-scale electricity from
hundreds to tens of thousands of MW with prices ranging from 4 to 40¢/kWh. Such power plants can be found in the
industrialized countries of the world like the United States and Europe as well as in the developing countries like Indonesia and
the Philippines. This green power technology is here to stay and will take a greater share of the electricity generation mix in the
years to come. As concerns about the availability and environ- mental impacts of fossil fuels become more and more widespread, the interest on environmentally benign renewable energy technologies will surely take center stage among engi- neers
and policymakers.
