Renewable energy standards: If it ain’t broke, don’t fix it

by

When your local utility buys more renewable energy to power your lights and computers, what more do you get besides the power?
You get cleaner air, fewer respiratory health problems, and lower health-care costs.
You get local jobs building and maintaining green power plants and a better foothold in the fast-growing, multi-billion dollar global renewable energy industry.
If you use the power to charge the new plug-in electric vehicles now available, you reduce our imports of foreign oil and increase our energy security.
And finally, you reduce the greenhouse gases that are leading to the severe, threatening weather events spurred by global climate change.

Indian villagers’ lives transformed by new energy delivery system

by

It’s late December and an icy fog cloaks the northeastern state of Uttar Pradesh. Here, far from the cities, smoke rises in dense, choking spirals from meagre wood fires and scantily-clad children shiver against the cold. These are largely farming families, and their mud huts fortified by the occasional brick wall are for the most part devoid of light, heat or clean water. But it is here in Uttar Pradesh, one of India’s largest and poorest states, far away from the country’s straining power grid, that US-born entrepreneurs Nikhil Jaisinghani and Brian Shaad have started to pioneer a wholly different energy system, designed to meet some of the most basic needs of the poorest.

Basking in the sun

Who hasn’t enjoyed heat from the sun? Doing so represents a direct energetic transfer—via radiation—from the sun’s hot surface to your skin…We have already seen that solar PV qualifies as a super-abundant resource, requiring panels covering only about 0.5% of land to meet our entire energy demand (still huge, granted). So direct thermal energy from the sun, gathered more efficiently than what PV can do, is automatically in the abundant club. Let’s evaluate some of the practical issues surrounding solar thermal: either for home heating or for the production of electricity.

Is deception no longer an adaptive human strategy?

by

“A lie is as good as the truth if you can get somebody to believe it.” So goes the cynical maxim. Naturally, it contradicts the accepted public morality embodied in the saying: “Honesty is the best policy.” That saying is attributed to Miguel de Cervantes though it has been repeated by many others. I rather think that the ancient Roman satirist Juvenal had it right when he wrote: “Honesty is praised and starves.”

ODAC Newsletter – Jan 13

Fears of an EU recession gained ground this week with news that the German economy shrank in Q4. In oil markets this dunked oil prices to a New Year low – though they quickly recovered on Thursday in response to renewed concerns of supply disruption. In Nigeria unions threatened to escalate nationwide strikes to the oil production sector at the weekend if the government fails to reverse recent cuts in fuel subsidies.

Warm and fuzzy on geothermal?

by

The Earth started its existence as a red-hot rock, and has been cooling ever since. It’s still quite toasty in the core, and will remain so for billions of years, yet. Cooling implies a flow of heat, and where heat flows, the possibility exists of capturing useful energy. Geysers and volcanoes are obvious manifestations of geothermal energy, but what role can it play toward satisfying our current global demand? Following the recent theme of Do the Math, we will put geothermal in one of three boxes labeled abundant, potent, or niche (puny). Have any guesses?

Riot 4 austerity results: cutting consumption by 50 – 85%

by

The Riot 4 Austerity 90% Emissions Reduction Project challenges participants to cut their negative environmental impact in seven different categories: transportation energy, electricity, other fuels (i.e. natural gas for heating), water, garbage, food, and consumer goods. As individuals, we may not have “much” impact, but the point is to model these positive changes for others, share results and tips, and work together to make the changes needed for society to follow. Hopefully, the changes each family makes will not only result in less environmental harm but monetary savings, greater life satisfaction, and improved health through more exercise and better food. Cutting consumption is not only good for the environment, but also helps prepare us for a world of declining energy and resource availability.

Occupy sustainability: the 1% is blocking the transition to a renewable energy economy

by

A sustainable world that works for the 99% is possible, if we can respond to climate change, economic injustice and resource depletion at the same time. The transition to a renewable energy economy can be a valuable frame for that discussion. Just as the financial elites brought about the economic crisis, they are blocking the renewable energy transition to reap more profit from their fossil fuel investments. Because of fuel depletion as well as climate change, further delay may prevent a successful transition. Social justice and sustainability advocates can blow the whistle on the 1% for this issue too, and collaborate to speed up the transition locally.
