Energy comes in many shapes and forms, from wind, solar power,
geothermal, and biomass to coal, natural gas, and petroleum. The
energy we consume is constantly changing, but the use of these
resources-whether renewable or nonrenewable-has long-term impacts
on our planet. While there has been this recent shift to renewable
energy within the United States, the worldwide demand for all
energy types continues to increase at a rapid rate. In fact, it has
increased by 84% over the past twenty years. Despite their
dwindling supply, these resources are still heavily relied on
today. Coal still accounts for 30% of the electricity generated by
the United States, even though natural gas is now the primary
energy used to produce electricity. Likewise, only 7% of
electricity usage worldwide is linked to solar and wind energy. In
The Changing Energy Mix, Paul F. Meier compares twelve renewable
and nonrenewable energy types using twelve common technical
criteria. These criteria span projected reserves, cost to the
consumer and supplier, energy balances, environmental issues, land
area required, and lasting impacts. While explaining the pros and
cons of these resources, Meier takes readers through the history of
energy in the United States and world. He provides insight into
energy sources, such as wind-powered and solar-powered electricity
(which did not exist until the mid and late 80s, respectively), and
he explains the constantly evolving world of energy. Breaking down
the potential promises and struggles of transitioning to a more
renewable energy-based economy, Meier explains the positive and
negative implications of these various sources of energy. The
resulting book equips readers with a unique understanding of the
history, availability, technology, implementation cost, and
concerns of renewable and nonrenewable energy.
