Earth Overshoot Day 2014

This year August 19th marked the day for "Earth Overshoot Day".... Now i'm sure you all are thinking what in the world is Earth Overshoot Day and why do i care. Well let me enlighten you. Earth Overshoot Day is the day of the year when mankind has used up all of earth's resources for that year. Meaning, everything we use of the earth's resources from August 19th on will be in excess to what the earth can produce in that given year. Attached is an article via Clean Techies that can give you some insight onto how important all this really is.   


August 19th is Earth Overshoot Day



It has taken less than eight months for humanity to use up nature’s entire budget for the year and go into ecological overshoot, according to data from Global Footprint Network, an international sustainability think tank with offices in North America, Europe and Asia.

Global Footprint Network tracks humanity’s demand on the planet (Ecological Footprint) against nature’s biocapacity, i.e., its ability to replenish the planet’s resources and absorb waste, including CO2.  Earth Overshoot Day marks the date when humanity’s Footprint in a given year exceeds what Earth can regenerate in that year. Since 2000, overshoot has grown, according to Global Footprint Network’s calculations. Consequently, Earth Overshoot Day has moved from early October in 2000 to August 19th this year.

“Global overshoot is becoming a defining challenge of the 21st century. It is both an ecological and an economic problem,” said Mathis Wackernagel, president of Global Footprint Network and the co-creator of the Ecological Footprint resource accounting metric. “Countries with resource deficits and low income are exceptionally vulnerable. Even high-income countries that have had the financial advantage to shield themselves from the most direct impacts of resource dependence need to realize that a long-term solution requires addressing such dependencies before they turn into a significant economic stress.”

In 1961, humanity used just about three-quarters of the capacity Earth had available for generating food, fiber, timber, fish stock and absorbing greenhouse gases. Most countries had biocapacities larger than their own respective Footprints. By the early 1970s, global economic and demographic growth had increased humanity’s Footprint beyond what the planet could renewably produce. We went into ecological overshoot.

Today, 86 percent of the world population lives in countries that demand more from nature than their own ecosystems can renew. According to Global Footprint Network’s calculations, it would take 1.5 Earths to produce the renewable ecological resources necessary to support humanity’s current Footprint. Moderate population, energy and food projections suggest that humanity would require the biocapacity of three planets well before mid-century. This may be physically unfeasible.

The costs of our ecological overspending are becoming more evident by the day. The interest we are paying on that mounting ecological debt in the form of deforestation, fresh-water scarcity, soil erosion, biodiversity loss and the build-up of CO2 in our atmosphere also comes with mounting human and economic costs.

Governments who ignore resource limits in their decision-making might put their long-term economic performance at risk. In times of persistent overshoot, those countries running biocapacity deficits will find that reducing their resource dependence is aligned with their self-interest. Conversely, countries that are endowed with biocapacity reserves have an incentive to preserve these ecological assets that constitute a growing competitive advantage in a world of tightening ecological constraints.



More and more countries are taking action in a variety of ways.

The Philippines is on track to adopt the Ecological Footprint at the national level — the first country in Southeast Asia to do so — via its National Land Use Act. This policy, the first of its kind in the Philippines, is designed to protect areas from haphazard development and plan for the country’s use and management of its own physical resources. Legislators are seeking to integrate the Ecological Footprint into this national policy, placing resource limits at the center of decision-making.

The United Arab Emirates, a high-income country, intends to significantly reduce its per capita Ecological Footprint – one of the world’s highest — starting with its carbon emissions. Its Energy Efficiency Lighting Standard will result in only energy-efficient indoor-lighting products being made available throughout the territory before the end of this year.

Morocco is interested in collaborating with Global Footprint Network on a review of the nation’s 15-year strategy for sustainable development in agriculture, Plan Maroc Vert, through the lens of the Ecological Footprint. Specifically, Morocco is interested comprehensively assessing how the plan contributes to the sustainability of the agriculture sector as well as a society-wide transition towards sustainability.

Regardless of a country’s specific circumstances, incorporating ecological risk into economic planning and development strategy is not just about foresight — it has become an urgent necessity

Solar Sector Keeping Investors Busy


In terms of investment dollars, corporate M&A, project funding and third-party capital, Q1 2014 was one of the strongest quarters on record.

Renewable Energy World Editors
April 08, 2014

New Hampshire, USA -- Highlighting once again that one of the key stories for renewable energy in 2014 will be renewable energy finance, Q1 2014 shows high growth for investments in solar. Total global corporate funding in the solar sector, including venture capital (VC), private equity (PE), debt financing, and other equity financings raised by public companies, came in at $7 billion, compared to $5 billion in Q4 2013, according to a report just released by Mercom Capital Group.

The report dives into venture capital funding, project funding, corporate mergers and acquisitions and third-party lease funding. All sectors showed an increase in the number of dollars invested and/or number of transactions showing just how favorably investors view solar.

Global VC funding, PE and corporate VC in Q1 2014 was almost double what it was in Q1 2013, totaling $251 million in 26 deals, up from $87 million in 24 deals in Q4 2013, mostly due to one large deal. Solar downstream companies attracted most of the VC funding this quarter, with $182 million in 13 deals.

Raj Prabhu, CEO of Mercom Capital Group, commented, “It was a robust quarter for solar as financing activity surged in almost all areas. The big story continues to be strong capital markets. VC funding was up with several funding deals involving investment “platforms,” while third-party residential/commercial funds continue to raise record amounts.”

The Tucson Solar Potluck: A Who’s Who of Solar in Arizona

via The Arizona Solar Center Blog:

On April 26, the Tucson Solar Potluck will be held in the desert north of Tucson. It is the 32nd straight year for the gathering of solar enthusiasts, a streak that some believe qualifies it as the longest continuously held solar event in the U.S.

The potluck was a focal point of a documentary film I produced about solar cooking in 1990.

In the early 1990s, CBS Sunday News did a news piece on the event as the highlight of its national Earth Day coverage.

People have come and gone over the years, yet every spring this “unusual gathering” takes place with an ever-changing cast of characters setting up the strangest of homemade contraptions and pointing them at the sun. Seemingly every sort of solar cooking device imaginable is on display, made from a variety of materials.

Phyllis and Bob Bright were potluck regulars more than two decades ago. The Brights had an oven that sat on the base of an office chair, thus allowing it to swivel to follow the sun. The Brights are gone now, but their office chair solar oven is still talked about and copied in design.

“Anything you can cook in a regular oven, I can cook in this [solar] oven,” Phyllis would boast in her thick New Jersey accent.

You know what – Phyllis was right. The solar oven is an all-purpose oven that can cook anything under the sun.

ABCO Solar Blog Tucson Electric Resource Plan Calls For More Renewable Energy, Less Coal Tucson Electric Resource Plan Calls For More Renewable Energy, Less Coal.

Tucson Electric Power (TEP) has unveiled a 15-year plan to reduce its coal generation capacity by about one-third, acquire new natural gas-fired resources, and continue its expansion of renewable power and energy efficiency programs.

TEP's plans are outlined in its 2014 Integrated Resource Plan (IRP) the company filed with the Arizona Corp. Commission on April 1. The IRP describes how TEP plans to meet energy demand requirements through 2028, providing reasonably priced service to customers while satisfying regulatory requirements and improving the environment.

According to current projections, the company expects to add more than 50,000 customers over the next 10 years. Peak demand is projected to grow annually by about 1% - 1.5%.

TEP says the IRP describes a long-term portfolio diversification strategy that will reduce the company’s reliance on coal-fired generation. The company plans to reduce its overall coal capacity by 492 MW - about 32% - over the next five years.

TEP plans to diversify its portfolio through continued investments in renewable energy and energy efficiency programs. By 2028, TEP anticipates that its combined solar, wind and biogas resource capacity will increase from 157 MW today to 788 MW. To replace some of the lost capacity from existing coal-fired resources, TEP and sister company UniSource Energy Services are planning a joint purchase of a 550 MW combined-cycle unit at the natural gas-fired Gila River Power Station in Gila Bend, Ariz.

TEP also plans to reduce its need for new generating resources through a range of energy-efficiency programs that it projects will result in a cumulative capacity reduction of 312 MW.

By 2028, TEP projects that its resource portfolio will consist of 43% coal-fired generation and 36% natural gas-fired resources. The remaining 21% will be made up of renewable energy resources and energy efficiency measures.
