Solar Impulse Launches Zero-Fuel Flight Around the World

http://info.solarimpulse.com/uploads/thumbs/860x576/2015_02_26_Solar_Impulse_2_RTW_First_Test_Flight_AbuDhabi_Revillard__09.jpgSolar Impulse is the first airplane to fly day and night on solar power alone. To be clear folks, that means 22,000 miles without a single drop of fuel.

Run on Sun has been following the exciting developments of Solar Impulse since it’s prototype began its groundbreaking test flight across America in 2013.

After the lessons learned from the American flight, an upgraded Solar Impulse 2 was developed with a wingspan wider than a Boeing 747, more than 17,000 solar cells and 1,300 pounds of batteries. Amazingly, the aircraft still weighs no more than an average car!

Finally, this  morning, on March 9th, 2015, Solar Impulse 2 and her team were ready to embark on their record-breaking aeronautical journey around the world. The first leg officially departed from Abu Dhabi at 7:12AM UTC+4. Landing in Muscat, Oman at 20:13PM UC+4 pilots Bertrand Piccard and Andre Borschberg rested for a few hours before continuing onward to Ahmedabad, India.

With a top speed of 50 mph, the entire circuit is planned to take four or five months before returning safely back to Abu Dhabi. You can follow their flight online as well as chat with the mission control center and view cockpit measurements like solar battery storage and pilot heart rate!

Solar Impulse is not only about accomplishing the first round-the-world solar flight. Behind the development of this technological feat lies a very powerful message. Piccard and Borschberg are using each landing as an opportunity to reach out to governments, NGOs, education centers, and the broader public to share what is possible with clean technologies.

“We shouldn’t be listing targets, but rather solutions – ways of meeting those targets. Because these solutions exist. Our society could already cut energy consumption in half by replacing old, outdated, polluting technology with clean technologies. Couldn’t we, all together, persuade governments to modify the legal framework so as to encourage the replacement of polluting technologies by cleantechs? That would at least make debates constructive and international climate conferences interesting.” - Bertrand Piccard

In conjunction with Solar Impulse’s round-the-world flight, the pilots started an online campaign called “Future is Clean”. In December 2015, they will share the largest collective voice in favor of clean technologies with global leaders at COP21, the United Nations Climate Change Conference in Paris.

Thirsty? Think Solar!

Water-Energy NexusHere in SoCal discussions on water conservation are a regular occurrence. We all know the management of water resources in California is critical given increasing populations, increasing strains on our enormous agricultural ‘breadbasket’, and ever-decreasing precipitation as the effects of climate change worsen. However, how many of us think about energy in terms of water conservation?

According to the International Energy Agency, energy production accounts for 15% of the world’s water withdrawal – water withdrawn from groundwater. Thermoelectric power plants account for over one third of the fresh water withdrawn in the US. Shockingly that volume is greater than the water used to grow our food!

So which energy sources are hogging our precious water and how? Actually, most energy generation technologies — including coal, nuclear, biomass and even concentrating solar power – consume astounding amounts of water.  It is necessary primarily for cooling thermal power plants, as well as fuel extraction, transport and processing. This results in both the depletion of available freshwater resources and affects the quality of our remaining resources downstream due to the polluting effects of energy-related outputs.

Global water use for energy productionSunlight, on the other hand, is an infinitely abundant resource in most water-stressed parts of the world, including here in California. The World Energy Outlook, published by the International Energy Agency reported that photovoltaic (PV) solar energy is one of only two electricity generation technologies with negligible water consumption.

PV energy systems provide a sustainable solution to the water-energy nexus by generating clean electricity with little to no water use. With the smallest carbon footprint, lowest life cycle water use, and fastest energy payback time in the industry, thin-film PV modules provide a sustainable solution to water scarcity and energy security.

Water conservation must be a priority in water-stressed parts of the world. While PV solar is unlikely to provide enough power for the entire state any time soon, individuals and businesses installing roof-top solar can make a positive difference. It turns out, not only in reducing air pollution from dirty energy but also in saving our water resources!

It is important to note the other half of the energy-water nexus. Energy is required to produce, treat, and distribute water. So, even if solar is providing your electricity, the water you use is still linked to polluting energy sources. Combining smart water conservation techniques, such as those suggested in this EPA list of household water saving methods, with going solar is the best bet for ensuring our planet’s resources will continue to provide for our future.

Gov Brown: We will get 50% of electricity from renewables by 2030!

Jerry Brown Inaugural SpeechCalifornia Governor Jerry Brown’s inauguration was historic in more ways than one. After all, this is his fourth term - despite the legal limit of just two (the term limit was imposed in 1990 after his earlier terms in the 70’s). But perhaps even more historic was the content of his exciting inaugural speech. Among many plans for a healthier and more economically viable state, Brown proposed ambitious green energy goals including growing renewable energy to 50% by 2030. Coincidentally, on Tuesday we posted a blog encouraging readers to support the policies and politicians defending and expanding solar opportunities.

Gov. Brown described California as an environmental policy trendsetter. We already lead the nation in solar energy usage, energy efficiency overall, cleaner cars and energy storage. However, with the majority of scientists agreeing that we must limit global warming to 2 degrees Celsius by 2050, much more comprehensive measures are necessary.

If we have any chance at all of achieving that, California, as it does in many areas, must show the way. We must demonstrate that reducing carbon is compatible with an abundant economy and human well-being.

He outlined the following three goals to accomplish by 2030:

  1. Increase from one-third to 50 percent our electricity derived from renewable sources;
  2. Reduce today’s petroleum use in cars and trucks by up to 50 percent;
  3. Double the efficiency of existing buildings and make heating fuels cleaner.

California is already on track to reach its goal of one third energy derived from renewable sources by 2020. So, although 50% by 2030 sounds bold because no one else is doing it, it is actually feasible. This could mean the continuation of tax breaks and other financial incentives for homeowners to go solar. Given that transportation accounts for 40 percent of California’s greenhouse gas emissions, incentives and infrastructure to get drivers in electric cars are also likely.

I envision a wide range of initiatives: more distributed power, expanded rooftop solar, micro-grids, an energy imbalance market, battery storage, the full integration of information technology and electrical distribution and millions of electric and low-carbon vehicles.

It won’t be easy accomplishing Brown’s goals with the oil industry leaders and some politicians opposing anything green. As mentioned in Tuesday’s post, we must remain diligent in supporting policies and politicians fighting for a cleaner world. By his speech, Governor Brown once again demonstrated that he is such a politician, with his practical and no-nonsense stance:

Taking significant amounts of carbon out of our economy without harming its vibrancy is exactly the sort of challenge at which California excels. This is exciting, it is bold and it is absolutely necessary if we are to have any chance of stopping potentially catastrophic changes to our climate system.

We are at a crossroads. With big and important new programs now launched and the budget carefully balanced, the challenge is to build for the future, not steal from it, to live within our means and to keep California ever golden and creative, as our forebears have shown and our descendants would expect.

US & China Agree on GHG Reductions - UPDATE

In a dramatic joint announcement coming out of the APEC summit in China, President Barack Obama and Chinese President Xi Jinping have committed to significant reductions in greenhouse gas emissions. (H/T climatecrocks.com)

The agreement calls on China to peak its GHG emissions by no later than 2030 and increase the use of non-fossil fuels to 20% by that date.  Meanwhile, the US will cut its GHG emissions by 26-28% (compared to 2005 levels) by 2025.  For the two largest emitters of GHG, these steps by the US and China are historic and much needed.

“As the world’s two largest economies, energy consumers and emitters of greenhouse gases, we have a special responsibility to lead the global effort against climate change,” Obama said Wednesday in a joint press conference with Xi.

UPDATE - We noted that this was a really big deal, but the graph below is truly the picture worth a thousand words:

Significance of US-China carbon deal

While the impact of the actions from the US and China alone are significant, as the graph shows, their greatest benefit is in serving as an example for other countries to follow.

Beyond the practical significance in helping to combat climate change, China’s commitment - coming as it does from the head of the Communist Party - takes away the deniers’ favorite argument: that it is meaningless for the US to act since China never will.  Well guess what, China is acting.

Sorry deniers, what else have you got?

2014 - Warmest Year Ever?

The folks over at NASA are reporting something that folks out here in the West will not find at all surprising: 2014 is on track to contend for the title of warmest year ever.  (No doubt this will come as a shock to folks who regularly watch Fox News.)  (H/T Climate Crocks.)

Warmest year ever?

The chart shows the temperature anomaly for 134 years with the zoom in on the five warmest. 2014 is the heavy grey line; 2010 (the hottest year on record) is in red.  (Oh, and contrary to the Fox canard about a global cooling trend, in fact of the five warmest years ever, two were in the past five - 2010 and 2013.)

Of course, 2014 isn’t over yet so the dotted lines provide a number of possible scenarios.  To give you a sense of how far “ahead” we are so far this year, if the remaining months simply hit their 21st century averages, 2014 will tie 2005 for the second warmest year ever.

Hang on to this link, you may need to refer to it next month over Thanksgiving dinner!
