Rather, policymakers should figure out how much renewable energy is worth to society (possibly attributing a different value to solar, wind,
geothermal
and biomass) and make utilities or governments pay extra for it.
Greed will not reverse human-caused climate change, and Trump’s executive orders will not stop the global process of phasing out coal, oil, and gas in favor of wind, solar, hydro, nuclear, geothermal, and other low-carbon energy sources.
Moreover, they must meet the need for new power lines to carry low-carbon solar, wind, geothermal, and hydroelectric power from remote areas (and offshore platforms) to population centers.
In this context, subsidies that promote the development of green technologies – wind, solar, bio-energy, geothermal, hydrogen, and fuel-cell technologies, among others – are doubly important.
Unfortunately, clean, renewable energy sources that do not emit carbon dioxide, such as wind power and
geothermal
power, are not yet sufficient.
Green and Galiana examine the state of non-carbon-based energy today – nuclear, wind, solar, geothermal, etc. – and find that, taken together, alternative energy sources would get us less than halfway toward a path of stable carbon emissions by 2050, and only a tiny fraction of the way toward stabilization by 2100.
In Kenya, new drilling techniques are tapping the country’s
geothermal
energy resources, adding hundreds of megawatts of generating capacity in recent years.
Japan and South Korea were third in the amount of grid-connected solar photovoltaic panels added in 2008; the Philippines was second for total
geothermal
power and third for total biomass power;Indonesia was third for total
geothermal
power.
But others, such as wind, solar, and geothermal, are in some circumstances already cost competitive – or nearly cost competitive – with fossil fuels.
Kenya’s new feed-in tariff has triggered a rapid expansion of
geothermal
capacity, and, at 300MW, the largest wind-farm project in sub-Saharan Africa.
Second, we must produce electricity with wind, solar, nuclear, hydroelectric, geothermal, and other non-carbon energy sources, or by capturing and storing the CO2 produced by fossil fuels (a process known as CCS).
This “conventional”
geothermal
energy has been used to generate reliable base-load electricity for more than 100 years, and is now used in many countries including Italy, Iceland, Japan, New Zealand, and the western United States.
But conventional
geothermal
power requires a natural source of large quantities of steam or hot water, and such sources are usually found only in volcanic regions, which rules out its use in large parts of the world.
More tantalizing for humanity’s need for widely available, clean base-load power is the non-conventional
geothermal
energy called “hot dry rocks,” or HDR.
The rising costs of fossil and fissile fuels will also make HDR more compelling, since the long-term economics of
geothermal
power is effectively quarantined from fuel price movements.
These first power stations will develop the operational and financial performance histories that will be necessary before HDR
geothermal
energy can begin making an impact on world energy supplies.
The road to HDR
geothermal
energy has been long and expensive, but, like all developing technologies, the basic research and development had to be done before commercial development could follow.
With power stations now being built, the signs are bright for widespread use of
geothermal
energy to generate clean, emissions-free base-load power.
Second, we need to shift to solar, wind, hydro, nuclear, geothermal, and other forms of energy that are not based on fossil fuels.
Some renewables, such as solar thermal power and
geothermal
energy, are also notoriously water-intensive.
Europe and Canada pledged $10 billion toward an ambitious project called the Africa Renewable Energy Initiative, which aims to install ten gigawatts of solar, wind, and
geothermal
capacity by the end of the decade.
Just as coal, oil, and gas must be transported long distances, so wind, solar, geothermal, and hydropower must be moved long distances through transmission lines and through synthetic liquid fuels made with wind and solar power.
In Kenya, a new feed-in tariff is triggering an expansion of wind and
geothermal
power.
Low-carbon primary energy means three options: renewable energy, including wind, solar, geothermal, hydropower, and biomass; nuclear energy; and carbon capture and sequestration, which means using fossil fuels to create energy, but trapping the CO2 emissions that result and storing the carbon safely underground.
We will need new technologies to mobilize large-scale solar power, wind power, and
geothermal
power.
The eurozone’s troubled periphery – including Greece, Italy, Portugal, Spain, and Ireland – offers excellent conditions for harvesting renewable energy from the sun, wind, and
geothermal
sources.
In Costa Rica, we pride ourselves on the fact that nearly all of our electricity is produced by renewable sources, including hydroelectric, geothermal, and wind.
Despite all of the optimistic talk about wind, solar, geothermal, and other sustainable, non-carbon-emitting energy sources, no alternative is remotely ready to shoulder the energy burden currently borne by fossil fuels.
Recent developments in wind, solar, tidal, bio-energy, geothermal, and fuel-cell technology are transforming the scope for low-carbon energy production.
US government funding for renewable energy technologies (solar, wind, geothermal, ocean, and bio-energy) totaled a meager $239 million, or just three hours of defense spending.
