Pump water from your well, or shallow surface source directly with Solar PV panels. Size your solar water pumping system with this step-by-step guide to defining, and building your solar water pumping project. Solar water pumping systems include solar PV panels, a controller, and the pump itself. The examples included in this audiobook match the model pump, with the solar power supply required to produce a given average water production per day.

The smallest flowering plant, on Earth, is one of the most powerful, and widespread: duckweed. Usually, considered a nuisance, duckweed, upon close examination, is an impressive crop, in photosynthetic value. Ethanol, an industry dominated by the Corn Industry (King Corn), faces many challenges, including large water draws, rising fertilizer costs, large diesel fuel bills, and unintended impacts on Food markets.

In our daily lives, we're surrounded by wires, pipes, utility poles, cell phone towers, and myriad other infrastructure that facilitates almost everything we do. Even though these systems are essential, when was the last time you gave them much thought? In On the Grid, Scott Huler sets out to understand all of the systems that shape our society - from transportation, water, and garbage to the Internet coming through our cable lines.

On March 11, 2011, an earthquake large enough to knock the earth from its axis sent a massive tsunami speeding toward the Japanese coast and the aging and vulnerable Fukushima Daiichi nuclear power reactors. Over the following weeks, the world watched in horror as a natural disaster became a man-made catastrophe: fail-safes failed, cooling systems shut down, nuclear rods melted.

Conventional wisdom has North America entering a new era of energy abundance thanks to shale gas. But has industry been honest? Cold, Hungry and in the Dark argues that declining productivity combined with increasing demand will trigger a crisis that will cause prices to skyrocket, damage the economy, and have a profound impact on the lives of nearly every North American.

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. The production of 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.

As the 20th century began, oil in Texas was easy to find, but the quantities were too small to attract industrial capital and production. Then, on January 10, 1901, the Spindletop gusher blew in. Over the next 50 years, oil transformed Texas, creating a booming economy that built cities, attracted out-of-state workers and companies, funded schools and universities, and generated wealth that raised the overall standard of living - even for blue-collar workers. No other 20th-century development had a more profound effect upon the state.

Renewable energy is good for your wallet. Those who see that opportunity are already seizing it … all the way to the bank. Green Is Good is a no-nonsense guide to how you, the average American, can easily incorporate clean energy and energy efficiency into your daily life and in the process save money, make money, and help wean your community off fossil fuels.

Today, there are over 100 nuclear reactors operating in our backyards, from Indian Point in New York to Diablo Canyon in California. Proponents claim that nuclear power is the only viable alternative to fossil fuels, and due to rising energy consumption and the looming threat of global warming, they are pushing for an even greater investment.

This thoroughly researched and wholly engaging book investigates the economic, ecological, political, and psychological issues behind the Keystone XL pipeline-a project so controversial it has inspired the largest expression of civil disobedience since the Civil Rights movement of the 1960s. With enough carbon trapped in the Canadian tar sands to plunge the Earth into irreversible climate change, it is the Keystone XL pipeline that will set that carbon free.

Our rapidly industrializing world has an insatiable hunger for energy and conventional sources are struggling to meet demand. Oil is running out, coal is damaging our climate, many nations are abandoning nuclear, yet solar, wind, and water will never be a complete replacement. The solution, says Daniel Clery in this deeply researched and revelatory book, is to be found in the original energy source: the Sun itself.

As fossil fuel prices rise, oil insecurity deepens, and concerns about climate change cast a shadow over the future of coal, a new energy economy is emerging. Wind, solar, and geothermal energy are replacing oil, coal, and natural gas, at a pace and on a scale we could not have imagined even a year ago. For the first time since the Industrial Revolution, we have begun investing in energy sources that can last forever. Plan B 4.0 explores both the nature of this transition to a new energy economy and how it will affect our daily lives.

When asked to name the world’s first major nuclear accident, most people cite the Three Mile Island incident or the Chernobyl disaster. Revealed in this book is one of American history’s best-kept secrets: the world’s first nuclear reactor accident to claim fatalities happened on United States soil. Chronicled here for the first time is the strange tale of SL-1, a military test reactor located in Idaho’s Lost River Desert that exploded on the night of January 3, 1961, killing the three-man maintenance crew on duty.

The near-meltdown of Fukushima, the upheavals in the Middle East, the BP oil rig explosion, and the looming reality of global warming have reminded the president and all U.S. citizens that nothing has more impact on our lives than the supply of and demand for energy. Its procurement dominates our economy and foreign policy more than any other factor. But the "energy question" is more confusing, contentious, and complicated than ever before.

A search for the contemporary Nikola Tesla - considered a mad scientist by his society for predicting global warming more than 100 years ago - fuels this analysis of climate issues, which introduces thinkers and inventors who are working to find possible ways out of the energy crisis. From Louis Michaud, a retired refinery engineer who claims we can harness the energy of man-made tornadoes, to a professor and a businessman who are running a company that genetically modifies algae so it can secrete ethanol naturally, these individuals and their unorthodox methods are profiled.

With the constant threat of oil shortages facing us and wanting to educate herself about possible alternatives, Gwyneth Cravens skeptically sets out to find for herself the truth about nuclear energy. Her conclusion: It is a totally viable and practical solution to global warming. She enlists the help of Rip Anderson, a leading scientist in the field of risk assessment, and with his tutelage, she travels the country, visiting uranium mines, enrichment centers, reactors, and waste sites.
