Note:Here begin a series of seven articles related to the possibility that the entire electricity consumption can proceed entirely from renewable energy by the 2030 year.
Introduction
The future plan to optimize the use of cheap renewable energy in the world the next 20 years would consist to build four million wind turbines of 5 MW, 1,700 million photovoltaic roofs of 3 kW, 90,000 solar plants of 300 MW (including both solar photovoltaic as solar thermal), plus a small portion of geothermal, wave energy and tide.
More recently, in 2009, a study by Stanford University ranked energy systems according to their impacts on global warming, pollution, water supply, land use, wildlife and other problems. The best options were, in order, wind, solar, geothermal, tidal and hydroelectric power - all of which are powered by wind, water or sunlight (known by the acronym WWS).Nuclear power, coal with CO2 capture and ethanol were the worst options, as well as oil and natural gas. The study also found that battery-electric vehicles and hydrogen fuel, could largely eliminate pollution in the transport sector.
This plan to reduce energy waste
requires millions of wind turbines, small hydro plants of low environmental
impact and solar energy, both photovoltaic and solar thermal. The numbers are
large, but the scale is not an insurmountable obstacle, our society has achieved massive transformations before.
An example;during World War II, the United States finished adapting automobile
factories to produce 300,000 aircraft, and other countries produced 486,000
aircraft. In 1956, the U.S. began the creation of the state highway system,
which 35 years later were extended to 47,000 miles, changing commerce and
society, after all. it's possible make
it with the everyone's effort.
Introduction
The future plan to optimize the use of cheap renewable energy in the world the next 20 years would consist to build four million wind turbines of 5 MW, 1,700 million photovoltaic roofs of 3 kW, 90,000 solar plants of 300 MW (including both solar photovoltaic as solar thermal), plus a small portion of geothermal, wave energy and tide.
The
calculations leave out biomass (because of pollution and land occupation) and
nuclear energy, as well as all non-renewable energy. Wind turbines are larger
than those currently operating, even
have been built some wind farms with turbines of 5 MW.
Cheap renewable
energy can provide 100 per cent of the world's energy, eliminating all fossil
fuels. By Mark Z. Jacobson (Stanford University) and Mark a. Delucchi (Univ.
California-Davis).Wind energy and solar energy in the right places would reduce
the energy consumed in the world. The authors reject biofuels and nuclear
energy. The authors plan requires large 3.8 million of 5 MW wind turbines,
90,000 solar thermal and photovoltaic installations and numerous geothermal,
tidal energy and solar roofs worldwide.The cost of generating and transmitting
power energy would be less than the projected cost per kilowat- hour of fossil
fuels and nuclear energy. There are limitations in shortage of some special
materials, together with the lack of political will, appear as major obstacles.
In previous
years, leaders from around the world gathered in Copenhagen to try to reach an
agreement on reducing emissions of CO2 and other greenhouse gases that have
been increased for decades. The most effective way to fulfill that goal would
be a huge change from fossil fuels to renewable energy sources. If leaders could have confidence
that such transformation is possible,
can undertake to an historic agreement,It's possible they will can do it.

A few years
ago former Vice President Al Gore threw a glove:off and back to turn on America
with 100% CO2-free electricity within ¡¡10 years !!. The viability of this
change was evaluated and take an even greater challenge: to determine how 100
percent of the energy consumed worldwide, for all purposes, could be supplied
by wind, water and sun, as early as in 2030.Scientists have
been accumulating pieces until present,so that in less than a decade, analyzing
different parts of the challenge, the objetive can be achieved; therefore the
target to have 100% cheapest renewable energy.

Is it
possible to transform the world's energy systems and reduce energy consumption? Could be done in almost two
decades? The answers depend of the chosen technologies, availability of
critical materials,technological advances of the renewable energy and economic factors and political efforts.In following articles we'll talk more opportunely each
of these aspects.
