The coming era of unlimited—and free—clean energy


Futurist Ray Kurzweil notes that solar power has been doubling every two years for the past 30 years....... He says solar energy is only six doublings — or less than 14 years — away from meeting 100 percent of today’s energy needs."



In the 1980s, leading consultants were skeptical about cellular phones.  McKinsey & Company noted  that the handsets were heavy, batteries didn’t last long, coverage was patchy, and the cost per minute was exorbitant.  It predicted that in 20 years the total market size would be about 900,000 units, and advised AT&T to pull out.  McKinsey was wrong, of course.  There were more than 100 million cellular phones in use 2000; there are billions now.  Costs have fallen so far that even the poor — all over world — can afford a cellular phone.

The experts are saying the same about solar energy now.  They note that after decades of development, solar power hardly supplies 1 percent of the world’s energy needs.  They say that solar is inefficient, too expensive to install, and unreliable, and will fail without government subsidies.  They too are wrong.  Solar will be as ubiquitous as cellular phones are.

Futurist Ray Kurzweil notes that solar power has been doubling every two years for the past 30 years — as costs have been dropping. He says solar energy is only six doublings — or less than 14 years — away from meeting 100 percent of today’s energy needs. Energy usage will keep increasing, so this is a moving target.  But, by Kurzweil’s estimates, inexpensive renewable sources will provide more energy than the world needs in less than 20 years.  Even then, we will be using only one part in 10,000 of the sunlight that falls on the Earth.

In places such as Germany, Spain, Portugal, Australia, and the Southwest United States, residential-scale solar production has already reached “grid parity” with average residential electricity prices.  In other words, it costs no more in the long term to install solar panels than to buy electricity from utility companies.  The prices of solar panels have fallen 75 percent in the past five years alone and will fall much further as the technologies to create them improve and scale of production increases.  By 2020, solar energy will be price-competitive with energy generated from fossil fuels on an unsubsidized basis in most parts of the world.  Within the next decade, it will cost a fraction of what fossil fuel-based alternatives do.

It isn’t just solar production that is advancing at a rapid rate; there are also technologies to harness the power of wind, biomass, thermal, tidal, and waste-breakdown energy, and research projects all over the world are working on improving their efficiency and effectiveness.  Wind power, for example, has also come down sharply in price and is now competitive with the cost of new coal-burning power plants in the United States.  It will, without doubt, give solar energy a run for its money.  There will be breakthroughs in many different technologies, and these will accelerate overall progress.

Despite the skepticism of experts and criticism by naysayers, there is little doubt that we are heading into an era of unlimited and almost free clean energy.  This has profound implications.

First, there will be disruption of the entire fossil-fuel industry, starting with utility companies — which will face declining demand and then bankruptcy.  Several of them see the writing on the wall.  The smart ones are embracing solar and wind power.  Others are lobbying to stop the progress of solar power — at all costs.  Witness how groups in Oklahoma persuaded lawmakers to approve a surcharge on solar installations; the limited victory that groups backed by the Koch brothers won in Arizona to impose a $5 per month surcharge; and the battles being waged in other states.  They are fighting a losing battle, however, because the advances aren’t confined to the United States. Countries such as Germany, China, and Japan are leading the charge in the adoption of clean energies.  Solar installations still depend on other power sources to supply energy when the sun isn’t shining, but battery-storage technologies will improve so much over the next two decades that homes won’t be dependent on the utility companies.  We will go from debating incentives for installing clean energies to debating subsidies for utility companies to keep their operations going.

The environment will surely benefit from the elimination of fossil fuels, which will also boost most sectors of the economy.  Electric cars will become cheaper to operate than fossil-fuel-burning ones, for example.  We will be able to create unlimited clean water — by boiling ocean water and condensing it.  With inexpensive energy, our farmers can also grow hydroponic fruits and vegetables in vertical farms located near consumers.  Imagine skyscrapers located in cities that grow food in glass buildings without the need for pesticides, and that recycle nutrients and materials to ensure there is no ecological impact.  We will have the energy needed to 3D-print our everyday goods and to heat our homes.

We are surely heading into the era of abundance that Peter Diamandis has written about — the era when the basic needs of humanity are met through advancing technologies. The challenge for mankind will be to share this abundance, ensuring that these technologies make the world a better place.

EXTRACT: "From a Kantian standpoint discrimination based on race – or religion, or gender – is fundamentally wrong. It is wrong, first of all, because it is dehumanizing, a denial of human dignity. When I racially discriminate, I am denying the person’s intrinsic self-worth, I am, in fact, denying their very right to exist, whether I know it or not. The moral law demands that I treat every individual as a free person equal to everyone else. If the moral law grants each of us a kind of infinite worth, it does not grant someone greater worth than anyone else."

EXTRACT: "Numerous studies have shown that children who grow up in more deprived neighbourhoods tend to have worse physical health as adults compared to those raised in more affluent areas. This is the case even when researchers take into account family income and education, and whether or not parents have major illnesses. In order to address this health disparity, researchers need to understand how those living in disadvantaged neighbourhoods end up with worse health outcomes. Our team’s latest study has highlighted one potential way your childhood neighbourhood may influence your health for years to come. It might do so through changing how the activity of your genes is regulated."

EXTRACT: "I know I’m good in a couple of things, really good in a few things, and that’s enough. My confidence is big enough that I can really let people grow next to me, it’s no problem. I need experts around me. It’s really very important that you are empathetic, that you try to understand the people around you, and that you give real support to the people around you."

EXTRACT: "The diverse, non-human life forms that live in our guts – known as our microbiome – are crucial to our health. A disrupted balance of these contribute to a range of disorders and diseases, including obesity, diabetes, inflammatory bowel disease. It could even affect our mental health..... It’s well known that the microbes living in our guts are altered through diet. For example, including dietary fibre and dairy products in our diets encourages the growth of beneficial bacteria. But mounting evidence suggests that exercise can also modify the types of bacteria that reside within our guts."

EXTRACT: "Bonhoeffer’s life holds an important lesson for us today, regardless of our religious affiliation or lack thereof. And simply put it is this: you are called upon; you are called on behalf of your neighbor. When you are called to be responsible that is not an obligation which you can decline, discharge or acquit yourself of – it is an infinite responsibility, a “forever commitment” as Charles Blow recently put it. And we all must be prepared to make any sacrifice necessary when we are called."

EXTRACT: "People differ substantially in how much they’re affected by experiences in their lives. Some people seem to be more affected by daily stress, or the loss of someone close to them. On the other hand, some people seem to get through the same experiences relatively unscathed. Similarly, some people benefit strongly from counselling, or having a support system of close family and friends. Others seem better able to manage on their own. But understanding why some people are more sensitive than others isn’t just a question of how they were raised, and the experiences they’ve been through. In fact, previous research has found that some people in general seem more sensitive to what they experience – and some are generally less sensitive."

EXTRACT: " The root causes of anthropogenic climate change – which has led to the endangering of countless species across the globe – cannot be adequately grasped in isolation from the technological application of modern science. While Swedish activist Greta Thunberg was certainly justified in calling upon American legislators to “unite behind the science,” neither can we overlook the culpability of science in bringing about the environmental crisis. "

EXTRACT: "The QAnon movement began in 2017 after someone known only as Q posted a series of conspiracy theories about Trump on the internet forum 4chan. QAnon followers believe global elites are seeking to bring down Trump, whom they see as the world’s only hope to defeat the “deep state.” OKM is part of a network of independent congregations (or ekklesia) called Home Congregations Worldwide (HCW). The organization’s spiritual adviser is Mark Taylor, a self-proclaimed “Trump Prophet” and QAnon influencer with a large social media following on Twitter and YouTube."

EXTRACT: "The aim of my research for the Understanding Unbelief programme was to investigate the worldviews of non-believers, since little is known about the diversity of these non-religious beliefs, and what psychological functions they serve. I wanted to explore the idea that while non-believers may not hold religious beliefs, they still hold distinct ontological, epistemological and ethical beliefs about reality, and the idea that these secular beliefs and worldviews provide the non-religious with equivalent sources of meaning, or similar coping mechanisms, as the supernatural beliefs of religious individuals."

EXTRACT: "Psalm 91, for example, reassures believers that God will protect them from “the pestilence that walketh in darkness… A thousand shall fall at thy side, and ten thousand at thy right hand; but it shall not come nigh thee”.............Luther was a devout believer but insisted that religious faith had to be joined with practical, physical defences against sickness. It was a good Christian’s duty to work to keep themselves and others safe, rather than relying solely on the protection of God. "

EXTRACT: "Strangely, those with strong beliefs tend to be admired. The human mind hates uncertainty, so it is comforting to be told what to think, and to form settled opinions. But it is not rational. As the philosopher Bertrand Russell wrote: “The fundamental cause of the trouble is that in the modern world the stupid are cocksure while the intelligent are full of doubt.”

Extract: "Humans, Boccaccio seems to be saying, can think of themselves as upstanding and moral – but unawares, they may show indifference to others. We see this in the 10 storytellers themselves: They make a pact to live virtuously in their well-appointed retreats. Yet while they pamper themselves, they indulge in some stories that illustrate brutality, betrayal and exploitation. Boccaccio wanted to challenge his readers, and make them think about their responsibilities to others. “The Decameron” raises the questions: How do the rich relate to the poor during times of widespread suffering? What is the value of a life? In our own pandemic, with millions unemployed due to a virus that has killed thousands, these issues are strikingly relevant.

Extract: "If we do not seize this crisis as a moment for transformation, then we will have lost the war. If doing so requires reviving notions of collective guilt and responsibility – including the admittedly uncomfortable view that every one of us is infinitely responsible, then so be it; as long we do not morally cop out by blaming some group as the true bearers of sin, guilt, and God’s heavy judgment. A pandemic clarifies the nature of action: that with our every act we answer to each other. In that light, we have a duty to seize this public crisis as an opportunity to reframe our mutual responsibility to one another and the world."

EXTRACT: "Death is the common experience which can make all members of the human race feel their common bonds and their common humanity."
