The modern environmental movement was born 45 years ago today. A small group of twenty-somethings with a passion for the environment rallied together to create a more earth-conscious society, establishing what has become known as Earth Day.

The original Earth Day focused primarily on the pollution issue, but this year’s Earth Day is heavily directed towards climate change and the energy infrastructure.

While there may be a war on science happening with people and politicians alike dismissing climate change as mere myth, scientists conducting research in the field state that evidence for warming of the climate system is unequivocal.

When looking at climate change on a global level, the numbers speak for themselves.

• Carbon dioxide levels are at their highest in 650,000 years
• Nine of the 10 warmest years on record have occurred since 2000
• Land ice is dropping by 258 billion metric tons per year
• Sea levels have risen nearly 7” over the past 100 years

Who needs batteries to power a camera? Engineers from Columbia University are working on a novel design in which the pixels of the camera not only capture an image, they also collect light as an energy source.

The engineers are researching a commonality between a typical camera and solar panels: photodiodes. Each device has always used photodiodes, but in different ways.

Engineers plan for the new camera to use photodiodes in both functions.

This year is shaping up to be a very green for the American energy sector. U.S. power emissions are expected to fall to a two-decade low in light of the year of “de-carbonization”.

Bloomberg New Energy Finance reports that CO₂ emissions from the power sector should drop to their lowest levels since 1994.

The factors most connect to this decline include:

• The instillation of more renewables than ever before—with around 18 new GW coming online.

• A record year for coal retirements—forecasting 23GW to come offline.

• The burning of more natural gas in 2015 than ever before.

A research team from Standford University has developed a high-performance aluminum battery.

Researchers have been attempting to make a commercially viable aluminum-ion battery for years. Now, a team from Stanford University may have developed just the thing to outpace widely used lithium-ion and alkaline batteries.

The new aluminum-ion battery demonstrates high performance, a fast charging time, long-lasting cycles, and is of low cost to produce.

“We have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames,” said Hongjie Dai, a professor of chemistry at Stanford.

The researchers were able to achieve this novel battery by applying graphite as the cathode material.

One small step for renewable energy, and one giant leap for Costa Rica.

Costa Rica has not burned one fossil fuel in over 75 days. The country is currently running completely on renewable energy, primarily due to heavy rains and geothermal energy.

The country is now producing enough electricity though hydropower systems, such as pump storage and run-of-the-river plants, to power the majority of Costa Rica. Pair that with additional geothermal, solar, and wind energy sources and 100 percent renewable energy efficiency is achieved.

Dan Fatton, ECS Director of Development & Membership services, spotted an article in My Central Jersey that details a potential game changer in sustainable energy.

Researchers from Rutgers University may have just found the key to advancing renewable resources and potentially growing an energy infrastructure based on sustainability.

The researchers from Rutgers’ Chemistry and Chemical Biology Department have recently developed a novel patent-pending energy storage technology grounded in electrochemical science. The new technology is said to not only be cost-effective, but also a highly efficient way to store sustainable energy for later use.

The research published in the journal Energy & Environmental Science addresses the feasibility of widespread utilization of sustainable power.

“We have developed a compound, Ni5P4 (nickel-5 phosphide-4), that has the potential to replace platinum in two types of electrochemical cells: electrolyzers that make hydrogen by splitting water through hydrogen evolution reaction (HER) powered by electrical energy, and fuel cells that make electricity from combining hydrogen and oxygen,” co-author of the study Charles Dismukes explained to My Central Jersey.

The development could help lead to safe, efficient artificial photosynthetic systems that replicate the natural process of photosynthesis that plants use to convert sunlight, water, and carbon dioxide into oxygen and fuel in the form of carbohydrates, or sugars.

The Electrochemical Society’s Nate Lewis is leading some pioneering research at Caltech with the vision of efficient, affordable, and effective renewable energy sources.

Dr. Lewis, an active member of ECS since 1982, has designed a novel electrically conductive film – which has the potential to result in the development of devices that can harness sunlight to change water into hydrogen fuel.

(Take a look at his plenary lecture on sustainable energy technology he gave at a past ECS meeting.)

“We’ve discovered a material which is chemically compatible with the semiconductor it’s trying to protect, impermeable to water, electrically conductive, highly transparent to incoming light, and highly catalytic for the reaction to make oxygen and fuels,” said Dr. Lewis.

He and his team have developed a process that allows the solar-driven production of fuel to be performed with record efficiency, stability, and effectiveness.

Annual U.S. solar PV installations saw a 30 percent increase in 2014 alone. (Click to enlarge.)

If you’re not excited about the promising potential of solar yet, you’re about to be.

According to a new report by GTM Research and the Solar Energy Industries Association (SEIA), solar is growing faster than all other sources of energy in the United States.

In the report U.S. Solar Market Insight 2014 Year in Review, GTM and SEIA were able to establish that solar is continuing its upward trend in the U.S. with an increase of 30 percent more photovoltaic installations than in 2013.

Not convinced yet? The analysts also paired solar against also forms of energy in their report. When compared to other non-renewable energy sources such as coal and natural gas, it showed equally impressive results.

Researchers, social scientists, and advocates are constantly examining the issue of the global lack of adequate sanitation in hopes to find an economic and sustainable solution. From Britain’s poo-powered bio-bus to the Gates Foundation’s effort to turn waste into drinking water – you can see the innovative answers popping up almost everywhere.

ECS has also joined the fight with our first Science for Solving Society’s Problems Challenge by awarding $210,000 of seed funding to innovative research projects addressing critical technology gaps in water and sanitation.

Now, researchers out of the University of West England are turning the focus from poop to pee with their new development in what they have termed urine-tricity.
