How Solar Power Could Slay the Fossil Fuel Empire by 2030
$this->bbcode_second_pass_quote('', 'I')n just 15 years, the world as we know it will have transformed forever. The age of oil, gas, coal and nuclear will be over. A new age of clean power and smarter cars will fundamentally, totally, and permanently disrupt the existing fossil fuel-dependent industrial infrastructure in a way that even the most starry-eyed proponents of ‘green energy’ could never have imagined.
These are not the airy-fairy hopes of a tree-hugging hippy living off the land in an eco-commune. It’s the startling verdict of Tony Seba, a lecturer in business entrepreneurship, disruption and clean energy at Stanford University and a serial Silicon Valley entrepreneur.
Seba began his career at Cisco Systems in 1993, where he predicted the internet-fueled mobile revolution at a time when most telecoms experts were warning of the impossibility of building an Internet the size of the US, let alone the world. Now he is predicting the “inevitable” disruption of the fossil fuel infrastructure.
Seba’s thesis, set out in more detail in his new book Clean Disruption of Energy and Transportation, is that by 2030 “the industrial age of energy and transportation will be over,” swept away by “exponentially improving technologies such as solar, electric vehicles, and self-driving cars.”
Two days after his JP Morgan lecture, Seba was addressing the 2014 Global Leaders’ Forum in south Korea, sponsored by Korean government ministries for science and technology, where he elaborated on the prospects of an energy revolution. Within just 15 years, he said, solar and wind power will provide 100 percent of energy in competitive markets, with no need for government subsidies.
Over the last year Seba has even been invited to share his vision with oil and gas executives in the US and Europe. “Essentially, I’m telling them you’re out of business in less than 15 years,” Seba said.
Revolutionary economics of renewables
For Seba, there is a simple reason that the economics of solar and wind are superior to the extractive industries. Extraction economics is about decreasing returns. As reserves deplete and production shifts to more expensive unconventional sources, costs of extraction rise. Oil prices may have dropped dramatically due to the OPEC supply glut, but costs of production remain high. Since 2000, the oil industry's investments have risen threefold by 180 percent, translating into a global oil supply increase of just 14 percent.
In contrast, the clean disruption is about increasing returns and decreasing costs. Seba, who dismisses biomass, biofuels and hydro-electric as uneconomical, points out that with every doubling of solar infrastructure, the production costs of solar photovoltaic (PV) panels fall by 22 percent. “The higher the demand for solar PV, the lower the cost of solar for everyone, everywhere,” said Seba. “All this enables more growth in the solar marketplace, which, because of the solar learning curve, further pushes down costs.”
motherboardOptimism Is in the Wind: The Wind Energy Generation Industry is Growing Stronger by the Year$this->bbcode_second_pass_quote('', 'T')he Production Tax Credit (PTC) is needed to keep wind energy nationally competitive, said Tom Kiernan, CEO of the American Wind Energy Association (AWEA) and the keynote speaker at this year’s Financial Forum Luncheon at Power Generation Week.
Despite this assertion, Kiernan remains bullish on the national market for wind-generated energy, noting that two states in the country, Iowa and South Dakota, currently generate over 25 percent of their energy via wind, with nine states currently generating 10 percent or more of their energy using wind.
Kiernan also said that wind energy is cheaper than many other conventional energy sources. Referencing a bill stub that Xcel Energy recently mailed to its customers announcing a 30 percent increase in the utility’s wind generation capacity, Kiernan emphasized that the company would pass the cost savings on to the customer. “That’s right,” he said, “Wind energy is not only good for the environment, it can also be the most economical energy choice.”
Kiernan also noted that wind energy costs continue to go down. Comparing the price of wind energy in 2011 to that in 2013, Kiernan noted that the cost per megawatt hour (MWh) of wind energy in Power Purchase Agreements (PPA) has steadily decreased, starting as high as $47 per MWh, and finishing as low as about $25 per MWh in some instances.
Kiernan acknowledged that the wind energy industry is young relative to more conventional sources of generation, but said this results in an environment in which evolution occurs rapidly. Wind towers have grown taller, he said, and blade designs and computer systems have improved dramatically.
While many people associate wind energy with high intermittency that requires more conventional forms of generation for backup, Kiernan demonstrated that wind energy actually requires about half the cost in reserves compared to those needed for conventional energy generation.
