How Solar Energy Became Cheap

Solar energy is a substantial global industry, one that has generated trade disputes among superpowers, threatened the solvency of large energy companies, and prompted serious reconsideration of electric utility regulation rooted in the 1930s. One of the biggest payoffs from solar’s success is not the clean inexpensive electricity it can produce, but the lessons it provides for innovation in other technologies needed to address climate change. Despite the large literature on solar, including analyses of increasingly detailed datasets, the question as to how solar became inexpensive and why it took so long still remains unanswered. Drawing on developments in the US, Japan, Germany, Australia, and China, this book provides a truly comprehensive and international explanation for how solar has become inexpensive. Understanding the reasons for solar’s success enables us to take full advantage of solar’s potential. It can also teach us how to support other low-carbon technologies with analogous properties, including small modular nuclear reactors and direct air capture. However, the urgency of addressing climate change means that a key challenge in applying the solar model is in finding ways to speed up innovation. Offering suggestions and policy recommendations for accelerated innovation is another key contribution of this book. This book will be of great interest to students and scholars of energy technology and innovation, climate change and energy analysis and policy, as well as practitioners and policymakers working in the existing and emerging energy industries.

How solar could spark a clean-energy transition through transformative innovation—creative financing, revolutionary technologies, and flexible energy systems. Solar energy, once a niche application for a limited market, has become the cheapest and fastest-growing power source on earth. What's more, its potential is nearly limitless—every hour the sun beams down more energy than the world uses in a year. But in Taming the Sun, energy expert Varun Sivaram warns that the world is not yet equipped to harness erratic sunshine to meet most of its energy needs. And if solar's current surge peters out, prospects for replacing fossil fuels and averting catastrophic climate change will dim. Innovation can brighten those prospects, Sivaram explains, drawing on firsthand experience and original research spanning science, business, and government. Financial innovation is already enticing deep-pocketed investors to fund solar projects around the world, from the sunniest deserts to the poorest villages. Technological innovation could replace today's solar panels with coatings as cheap as paint and employ artificial photosynthesis to store intermittent sunshine as convenient fuels. And systemic innovation could add flexibility to the world's power grids and other energy systems so they can dependably channel the sun's unreliable energy. Unleashing all this innovation will require visionary public policy: funding researchers developing next-generation solar technologies, refashioning energy systems and economic markets, and putting together a diverse clean energy portfolio. Although solar can't power the planet by itself, it can be the centerpiece of a global clean energy revolution. A Council on Foreign Relations Book

Solar Power Finance Without the Jargon introduces financial concepts through a lively history of the solar industry, and cuts through the main areas of mystique and misinformation about solar technology and projects. With extensive experience in answering questions from clients in the solar, finance and energy industries, Chase focuses on the practical and financial aspects of solar power, making this book suitable for those wanting to work in clean energy or who have a strong interest in the subject, particularly those without a business background.Since the first edition was published in 2019, solar capacity has only grown bigger and cheaper, opening up new markets. Most significantly, Russia invaded Ukraine in 2022, igniting an energy crisis across the world which made countries glad of any renewable energy capacity they had built, as well as amplifying calls for a diversified and resilient global supply chain for renewable energy components. This second edition of Solar Power Finance Without the Jargon is considerably more detailed and optimistic about batteries and hydrogen. It extensively updates readers on the rapidly-changing price and energy landscape, the latest industry thinking on the effects of large volumes of renewable energy on the grid and the path to deep decarbonisation of human civilisation.

Here is the truth that the powerful Dirty Energy public relations machine doesn't want you to know: the ascent of solar energy is upon us. Solar-generated electricity has risen exponentially in the last few years and employment in the solar industry has doubled since 2009. Meanwhile, electricity from coal has declined to pre-World War II levels as the fossil fuel industry continues to shed jobs. Danny Kennedy systematically refutes the lies spread by solar's opponents—that it is expensive, inefficient, and unreliable; that it is kept alive only by subsidies; that it can't be scaled; and many other untruths. He shows that we need a rooftop revolution to break the entrenched power of the coal, oil, nuclear, and gas industries Solar energy can create more jobs, return our nation to prosperity, and ensure the sustainability and safety of our planet. Now is the time to move away from the dangerous energy sources of the past and unleash the amazing potential of the sun.

How will the world be powered in ten years' time? Not by fossil fuels. Energy experts are all saying the same thing: solar photovoltaics (PV) is our future. Reports from universities, investment banks, international institutions and large investors agree. It's not about whether the switch from fossil fuels to solar power will happen, but when. Solar panels are being made that will last longer than ever hoped; investors are seeing the benefits of the long-term rewards provided by investing in solar; in the Middle East, a contractor can now offer solar-powered electricity far cheaper than that of a coal-fired power station. The Switch tracks the transition away from coal, oil and gas to a world in which the limitless energy of the sun provides much of the energy the 10 billion people of this planet will need. It examines both the solar future and how we will get there, and the ways in which we will provide stored power when the sun isn't shining. We learn about artificial photosynthesis from a start-up in the US that is making petrol from just CO2 and sunlight; ideas on energy storage are drawn from a company in Germany that makes batteries for homes; in the UK, a small company in Swindon has the story of wind turbines; and in Switzerland, a developer shows how we can use hydrogen to make 'renewable' natural gas for heating. Told through the stories of entrepreneurs, inventors and scientists from around the world, and using the latest research and studies, The Switch provides a positive solution to the climate change crisis, and looks to a brighter future ahead.

An innovative analysis that shows how the shift to solar energy—in particular, the use of photovoltaic cells—is both economically advantageous and inevitable, and will rival the information and communication technologies revolution in its transformative effects. In Solar Revolution, fund manager and former corporate buyout specialist Travis Bradford argues—on the basis of standard business and economic forecasting models—that over the next two decades solar energy will increasingly become the best and cheapest choice for most electricity and energy applications. Solar Revolution outlines the path by which the transition to solar technology and sustainable energy practices will occur. Developments in the photovoltaic (PV) industry over the last ten years have made direct electricity generation from PV cells a cost-effective and feasible energy solution, despite the common view that PV technology appeals only to a premium niche market. Bradford shows that PV electricity today has become the choice of hundreds of thousands of mainstream homeowners and businesses in many markets worldwide, including Japan, Germany, and the American Southwest. Solar energy will eventually be the cheapest source of energy in nearly all markets and locations because PV can bypass the aging and fragile electricity grid and deliver its power directly to the end user, fundamentally changing the underlying economics of energy. As the scale of PV production increases and costs continue to decline at historic rates, demand for PV electricity will outpace supply of systems for years to come. Ultimately, the shift from fossil fuels to solar energy will take place not because solar energy is better for the environment or energy security, or because of future government subsidies or as yet undeveloped technology. The solar revolution is already occurring through decisions made by self-interested energy users. The shift to solar energy is inevitable and will be as transformative as the last century's revolutions in information and communication technologies.
