The economy can’t grow forever

Commentary: The whole planet must live within its means
By Rex Nutting, MarketWatch

This is an excerpt. Read the full article here.

Those of us who believe that the economy should serve us instead of the other way around are conflicted.

We know that the only way to end unemployment at home and poverty around the world is to make the economy grow faster. But we also know that nothing can grow forever, that the faster the global economy grows, the sooner we’ll run out of essential resources, including fossil fuels, water, arable land, healthy ecosystems and moderate climate.

Economists and politicians can’t admit it, but the laws of physics apply, no matter what the latest polls tell us. The Earth has finite resources that will someday limit our economic growth.

World leaders gather at the United Nations, where tackling global poverty is high on the agenda. Video courtesy of Reuters.

The Earth cannot forever support 7 billion people consuming as much as Americans consume. And yet we’ve staked our future — individually, nationally, and maybe even as a species — on that impossible dream.

Book: The Post Carbon Reader

The Post Carbon Reader
Managing the 21st Century’s Sustainability Crises

Edited by Richard Heinberg and Daniel Lerch
In the 20th century, cheap and abundant energy brought previously unimaginable advances in health, wealth, and technology, and fed an explosion in population and consumption. But this growth came at an incredible cost. Climate change, peak oil, freshwater depletion, species extinction, and a host of economic and social problems now challenge us as never before. The Post Carbon Reader features articles by some of the world’s most provocative thinkers on the key drivers shaping this new century, from renewable energy and urban agriculture to social justice and systems resilience. This unprecedented collection takes a hard-nosed look at the interconnected threats of our global sustainability quandary—as well as the most promising responses. The Post Carbon Reader is a valuable resource for policymakers, college classrooms, and concerned citizens.

Water vs Energy - Special Report by IEEE Spectrum

The Coming Clash Between Water and Energy

Our thirst for water competes with our hunger for energy. Only radical new ideas will get us out of this mess
Consider a giant sponge, with limbs and tentacles that reach to the horizon. It dips into distant rivers, it delves for deep waters, it digs ditches to catch the rain—all to slake its insatiable thirst.

Clearly, this is no ordinary sea creature quietly snuffling the currents. We have met this sponge, and it is us. We humans are the thirstiest of creatures, and we’ve developed a nearly insatiable taste for this simple but delectable arrangement of hydrogen and oxygen atoms. But we need more. So much more.

We’re not talking about just drinking or bathing. Without water, we’d have practically no energy. Without energy—and therefore cars, planes, laptops, smartphones, and lighting—we wouldn’t be doing much.

In almost every type of power plant, water is a major hidden cost. Water cools the blistering steam of thermal plants and allows hydroelectric turbines to churn. It brings biofuel crops from the ground and geothermal energy from the depths of the Earth. Our power sources would be impotent without water.
Podcast

IEEE Spectrum's June Special report is about “The Water-Energy Nexus.” It sounds wonky, but it’s a subject about which you’ll inevitably be hearing more and more. In coming years, we’ll undoubtedly face the quandaries of the Water-Energy Nexus because many renewable technologies come with big water tradeoffs. IEEE Spectrum’s Senior Editor, Sam Moore, is with us to discuss the special report in this podcast, and acquaint us with some of the stories.
