Green, climate change, and bio-environmental impact  - 
 
Cows, doors and climate change

The world's 1.5 billion cows - and other livestock and ruminants - are an important source of greenhouse-gas emissions.

These emissions are estimated at about 2,000,000,000 metric tons of CO2-equivalent per year. A huge number that is sometimes seen as an evidence of the world’s inevitable shift towards disaster and climate change. 

On the other hand, the world’s CO2 emissions from energy consumption is estimated at about 35,800,000,000 metric tons, a big chunk of which comes from the energy consumption of our buildings – about 40% in the USA and in Europe. 
That is, buildings energy consumption amount to about 7 times the emissions coming from cows and other animals.
It’s a surprising number, not wholly unexpected… After all there are many billions of homes, offices, schools and other buildings; and they consume most of the electricity produced worldwide (most of which comes from fossil-fueled power plants), and a significant part of the natural gas.

But the most surprising is the importance of features that are ignored or undervalued.

An example? The exterior doors, of our homes, schools, offices... 
It is often estimated that they account for more than 10% of the energy wasted in our buildings. And if we take this estimate and do some basic calculations, it’s easy to conclude that… 
Inefficient exterior doors are responsible for an amount of green-house emissions equivalent to those coming from cows and other livestock. It’s as if there were 1.5 billion cows and other animals in our buildings. 

And it doesn’t have to be this way. Inefficient exterior doors are a major and unnecessary source of global warming. Zero energy buildings – using very energy efficient doors and windows, very high levels of insulation, efficient equipment and proper design and renewable sources of energy - are within our immediate reach. They are critical to addressing climate change.

Fossil fuels  - 
 
good chart to counteract Koch brothers propaganda that says solar gets 40 billion in subsidies a year (http://ecowatch.com/2015/02/20/solar-battle-koch-brothers-front-groups explains more), when total solar market is just 15 billion.  Republicans sometimes believe ANYTHING Koch guys say thru their front groups.  Solar doesn't even get 4 billion in subsidies. :)
 
The truth is to this day fossil fuels that cause carcinogenic smog and kill us all slowly got more government subsidies than renewables in most nations.  It's time for us all to take charge of the future, drive electric, install solar panels, inform peers and demand greener policies. :)  

Have you guys noticed how, while the oil price has been flat at $50 a barrel for 4 months, the gasoline price has been increasing 50% over the same period from $2 to $3 a gallon?  This is due to Big Oil monopoly and price setting. The so called "free market economics" that works for Oil Billionaires:). lol

Oil-gas-coal produce smog that causes early death for billions of people. :)  Cornell University says 40% of deaths are due to pollutionhttp://www.news.cornell.edu/stories/2007/08/pollution-causes-40-percent-deaths-worldwide-study-finds  

some reasons for buying your next car electric, installing solar panels and supporting solar-wind-green energy:

1.  help humanity since you no longer generate carcinogenic exhaust, otherwise known as smog, which kills millions of people each year ► http://goo.gl/jDj0hI and leads to lower IQ ► http://goo.gl/alNQIk and autism ► http://goo.gl/66nqwr.  

2.  save lives since you reduce heart attacks caused by traffic noise ►  http://goo.gl/Fuhvn.   Electric cars are much quieter.

3.   save humanity from oil wars that destroy the environment and kill countless civilians.  Iraq war trillions could have powered all US with solar/wind ► http://goo.gl/ZqN47.  

4.  you no longer have to change oil or spark plugs; no more smog check either; electric cars have 60% less parts, so you will go for repairs much less.  Combustion engines are noisy and only 15% efficient;  electric motors are 90% efficient. 

5.  bring the end of gas stations that poison the water wells with MTBE or other compounds leading to billions of dollars wasted in cleaning up the well water (example:  $0.4 billion settlement ► http://goo.gl/eKasZD)

6.  save money as you spend 3-6 times less money on "fuel" depending what area of the globe at the current low prices of oil.  If you have enough solar panels,  you get free CLEAN fuel for life, since you charge at home and utilities pay you for energy you put on the grid.  Likewise, Tesla Motors offers free solar ☼ charging for lifehttps://www.youtube.com/watch?v=wgk5-eB9oTY?  

7.  save money for noble purposes because electric cars are cheaper than many oil cars after the federal and state rebates:  in Colorado, you can buy a Nissan Leaf for only 15, 000, while in most other states for 18-21, 000.  A Smart EV costs only $12, 000 in Colorado, see http://smartusa.com.  Mitsubishi i-MieV is only $13, 000 in California and $10, 000 in Colorado ► http://www.evworld.com/news.cfm?rssid=31881

8.  electric car batteries and solar panels are far greener than alternatives.  Battery recycling for today's oil car lead batteries is happening at a 97% rate globally. It will be even better for the far safer lithium car batteries.   Lithium Ion batteries are classified by the federal government as non-hazardous waste.  Lithium ion batteries are made from nontoxic lithium carbonate (used in ovenware), nontoxic cobalt oxide (in pottery glaze), nontoxic graphite (in pencils), and a polymer (plastic) membrane. The most toxic components are the electrolyte and lithium cobalt oxide, neither of which are persistent in the environment and both of which are increasingly being replaced by safer compounds.  Wang Chuan-Fu, CEO of BYD, demonstrated the safety of the electrolyte in their lithium ion batteries by drinking it. Zero Motorcycles founder Neal Saiki said that the Lithium Ion batteries they use are safe to eat

Solar is way better than coal, oil or natural gas which spew 100-1000 times more carcinogens in the environment per unit of energy produced, besides far more CO2.  How long does a solar panel system have to operate to recover the energy used for making the panel? Energy payback for rooftop panels is 1-4 years depending on type.   Assuming a life of 30 years for a panel, that means that most energy produced will be free from pollution of any sort ► http://www.nrel.gov/docs/fy04osti/35489.pdf.   

9.  save time, thus money, since you are allowed to use the carpool lanes to avoid traffic if you drive an electric car, in many countries, even if there is only 1 person in the car.  

10. http://www.news.cornell.edu/stories/2007/08/pollution-causes-40-percent-deaths-worldwide-study-finds explains that 40% of deaths due to pollution.  Smog kills billions earlier.  Natural gas and Coal can be replaced with solar-wind immediately:) as a public health priority, especially since they are cheaper in many areas than fossil fuels and storage eliminates the need for sun-wind 24-7 ► http://www.youtube.com/watch?v=PjNKz8qXRmk.  In China's worst areas, smog makes people live only 4 decades ►  http://www.youtube.com/watch?v=-1DNjJd2YfA.   Coal-fired plants lead to birth defects in China, see the 2 min video ► http://www.youtube.com/watch?v=1wImJC6xEoU.  In all nations, including USA, people near coal-fired plants often die of cancer at 45 or so, see the 10 min video ► http://www.youtube.com/watch?v=KZWAQ_3yoj8.  Coal pollution leads to cancer, asthma, autism (mercury), etc. Clean coal doesn't exist ► http://www.youtube.com/watch?v=_l0iqdfFyC0.

11.  Germany increased its solar capacity 16000 times between 1990 and 2012https://plus.google.com/110265788529286523789/posts/2K5Ln8zyrqH.  It's possible.   In 2014, Denmark generated 39% electricity from wind ► https://plus.google.com/110265788529286523789/posts/1FraSFPpWBv. For comparison, the renewables percentage in the US is 15%, India & Australia & China 13%,   Germany 31%, Paraguay & Norway & Lesotho & Bhutan 100% (hydro), All Africa 32% (hydro), Japan 11%, Russia 15% (hydro), Mexico 26%, Indonesia & UK 18%, Canada 60% (hydro), Portugal 60% (hydro+wind), Brazil 90% (hydro), Iceland 100% (hydro+geothermal), Ghana 75% (hydro), Spain 45% (wind-solar-hydro),  New Zealand 80% (hydro+geoth+wind).

General Discussion  - 
 
Retail Sustainability: Do Shoppers Even Care?
1) Approximately half of shoppers think sustainability is very important or extremely important.
2) Sustainability matters most to baby boomers, the wealthy, urbanites and women.
3) More than half of shoppers say they feel better about shopping venues that have sustainability initiatives. 
4) Nearly half of shoppers notice sustainability measures, particularly younger shoppers and those in urban settings.
5) Recycling is the most noticed sustainability measure. 
#Sustainability #Retail
Until recently, there was scant data to help owners understand whether shoppers even noticed the green features of retail buildings and, if so, whether those initiatives impacted their loyalty towards certain retail projects.

Why Delhi's government should look to solar, not coal | http://goo.gl/85DIi9
Back to the past: The AAP's demand for cheap coal power for Delhi is unrealistic and wrong-headed. This is Arvind Kejriwal's plan to provide power to Delhi: He has asked the government to supply a coal block for a new ultra mega power plant. This plant would then be operated by a private company ...

Solar  - 
 
good news:  another almost 1 billion dollars for solar panels on roofs :).  exciting.  :)  
 
SolarCity and Google partner on $750 million solar fund, largest of its kind :)

The two Silicon Valley companies are teaming up on a fund expected to finance $750 million in residential solar projects across 14 states -- including California -- and the District of Columbia, which the companies say would be the largest nest egg of its kind. Google will put in $300 million, which the search giant said was its largest renewable-energy investment yet, topping the $280 million invested in a similar SolarCity fund in 2011.

Jonathan Bass, vice president of communications for SolarCity, said the $750 million -- which will include $450 million in debt financing -- will cover solar systems for 25,000 homes, and the company expects to fully exhaust the cash in 2015.


1.3 million Earths fit into the Sun.  The solar energy reaching the Earth is 5000 times the energy we use globally.  Some countries increased their solar capacity 5000-16000 times in 22 years.  

Solar ☼☼ energy can power the whole planet many times over thru solar windows, walls, roofs, roads, car paint, solar-electric cars-planes-ships-trains and battery storage.  This would eliminate arsenic, mercury, sulfur and other forms of pollution and increase life expectancy by many years. Here are some recent exciting solar power-electric car news:

1.  The Cost Of Solar Has Dropped 100 times Since 1977, Bringing Solar Power To Grid Parity in many areas.  More than half the present global solar PV capacity was installed in the last 3 years.  First Solar says solar module costs will halve over the next few yearshttp://reneweconomy.com.au/2014/solar-costs-to-halve-as-gas-prices-surge-27907.  The age of renewables has begun, according to Citigroup ►  http://reneweconomy.com.au/2014/citigroup-says-the-age-of-renewables-has-begun-69852.  Morgan Stanley says that we are nearing the tipping point for going off-grid with solar/wind/green power, battery storage and electric cars ► http://reneweconomy.com.au/2014/say-investors-wake-solar-pro-sumers-24413

2. Solar power sells now at 5c/kwh - cheaper than 7c for natural gas and 10 cents for coal in many places as shown by this latest SunEdison contract for 150MW ► http://reneweconomy.com.au/2014/cheapest-solar-sunedison-sells-solar-pv-output-at-5ckwh-25296.

3.  2014 electric car sales went up 58% versus 2013 ►  http://evobsession.com/nissan-leaf-takes-30-non-tesla-us-electric-car-market-2014/.  

4.  Another German state reached 100% renewables energy in 2014http://www.renewablesinternational.net/german-state-to-go-100-renewable-power-this-year/150/537/79472/.  Japan launched $0.1 billion program to support battery storage for solar panelshttp://reneweconomy.com.au/2014/japan-launches-battery-storage-subsidy-homes-business-51085

5.   Latin America solar power installed in 2014 was 3.7 times higher than in 2013http://cleantechnica.com/2015/01/29/latin-america-solar-market-grew-370-2014/

6.  China installed 11 GW (more than the total electrical capacity of Greece) of solar in 2014 ► http://www.pv-tech.org/guest_blog/china_2014_still_10.5_to_12gw_despite_new_policies_favouring_distributed_so.  India plans 10GW of solar by 2022http://cleantechnica.com/2014/11/23/india-eyes-100-gw-solar-power-capacity-2022/. :) India also plans 100 GW of wind by 2022http://cleantechnica.com/2015/01/25/india-plans-100-gw-wind-energy-capacity-2022/.  

7.  US is in the process of installing 43 GW of solar - enough to power 6 million homes ► http://goo.gl/Qbkunh.   50% electricity from wind in Iowa will be real soon due to $1 billion turbine order ►http://goo.gl/uJ4bdY

8.  Due to price drops you can invest 7k now and get 50k over 40 years. solar is the best one time investment you can make.  www.freecleansolar.com is probably one of the cheapest ways anyone in USA can install solar panels. $2/watt plus install and $500 in permits etc. They are where little guys buy their panels at wholesale. They connect you with local installers who do it all if you don't like installs. It costs now only 13k to buy and install a 5kw system. Plus you get 30% back as tax credit. It costs 10k if you choose a local electrician, as they charge 2000 not 5000 as the professional dolar installers for installing it. 10k means 7k after tax credit. That means for 7k you can eliminate 50000 in electricity costs over next 40 years. To me this is a perfect deal. Utilities limit your system to 5kw or so depending on how much you use. If you go to solarcity or others you end up paying 50-80% more. Panels on the roof make your house easier to sell. You can google "cheapest solar installers in your country" and take a step towards saving money and the environment.

9.  In Scotland 100% renewable energy by 2025 is the goal ► 
http://ecolocalizer.com/2010/09/29/scotland-aiming-for-100-clean-energy-by-2025/.  Tasmania has set a 100% renewable energy in 2020 goal ► http://goo.gl/3VfHOV.  The Philippines also has a 100% renewable energy in 10 years target ►  http://goo.gl/bZoeh.

10.  On May 11th 2014, Germany produced 74% of energy from solar+renewableshttp://reneweconomy.com.au/2014/germany-62168.  

11.  In October 2013 France has made its natural gas fracking ban absolute, in a victory for supporters of solar ► http://thinkprogress.org/climate/2013/10/11/2773071/france-frack-ban/.  Fracking causes small earthquakes, poisons ground water and air and makes millions of people sick ► http://www.youtube.com/watch?v=Xg4VNGFP6qE.  On December 19, France approved taxing fossil fuels to speed up solar deployment ► http://goo.gl/6J3eXC.

12.  Sao Paulo, with a metropolitan area of 20 million people, has set 70% electricity from renewables by 2020 goalhttp://goo.gl/JhmSlG.   

13.  Coal India, world's largest coal company, believes the future is renewables and started installing solar panels at their facilitieshttp://goo.gl/NXEOv.

14.  California town of Lancaster requires all new homes to come with installed solar panelshttp://goo.gl/t22RF.  20% of new homes in California will come with solar panels and most new electricity installed in California will be solar next 6 months.  

For the benefits of installing solar power on your roof, see *http://costofsolar.com*.  For more solar statistics and good news, you can read below: 

Figure 6 at ► http://goo.gl/bcCGh shows a graph of Shell Oil predicting solar energy will be main source of energy in 2070.  If even Oil companies admit to it, it means it will happen so much sooner.   Solar could reach 90% in 2025 if the world gets serious about eliminating pollution from smog by ending billions of Big Oil-Gas-Coal taxpayer subsidies and supporting solar instead. The Italian solar capacity increased 150 times from 2007 to 2011 ► http://goo.gl/YZGkE.  The German solar capacity increased 16000 times from 1991 to 2012http://goo.gl/qulHp.  Pollution causes 40% of deaths ► http://goo.gl/2sXL3, it is therefore a matter of public health to switch to solar energy. We can use solar car paint, walls, roads ► http://www.youtube.com/watch?v=3Gb4Qsecwvc, roofs, shingles ► http://www.youtube.com/watch?v=gXNTKGhbqKw, windows ► http://www.youtube.com/watch?v=Lru7kjhYkEI with no transmission lines that add EMF pollution & take space.

On June 9th 2014 Germany produced 50% electricity from solarhttp://www.thelocal.de/20140619/germany-produces-half-of-electricity-needs-with-solar-power.

Distributed ► http://goo.gl/uz7o0 rooftop solar eliminates a lot of EMF pollution coming from transmission lines and gives more power to the people instead of Big Utilities.  *Portugal reached 70% electricity from renewables* ► http://goo.gl/aQUJx and India solar achieved grid parity ► http://goo.gl/1Itzd. :)  

Solar power is now cheaper than oil burning in Saudi Arabiahttp://goo.gl/1fG55, cheaper than grid power in Brazil ► http://goo.gl/jJHPE and in part of US ► http://goo.gl/B5Gtk , cheaper than kerosene for 1.3 billion people (in Africa and many developing nations) ► http://goo.gl/49Nej.  Fossil fuels are on the way out in EU ► http://goo.gl/x7Uxt.  Italian and German solar power reached grid parity a while ago ► http://thinkprogress.org/climate/2014/03/24/3418145/solar-grid-parity-italy-germany/.

Future Fusion can be safe, it's how the sun generates energy. But present nuclear energy is too dangerous, Thorium included ► http://phys.org/news/2012-12-thorium-proliferation-nuclear-wonder-fuel.html.   Some say Fukushima is worse than Chernobyl ► http://www.youtube.com/watch?v=zauXF70o6ik, hence Japan is now ramping up solar power a lot.   http://www.youtube.com/watch?v=rvAJ_u3Q0Hw shows the effects of current nuclear tech gone bad. 

Coal can be replaced with solar immediately:) as a public health priorityhttp://www.youtube.com/watch?v=PjNKz8qXRmk.  In China's worst areas, smog makes people live only 4 decades ►  http://www.youtube.com/watch?v=-1DNjJd2YfA.   Coal-fired plants lead to birth defects in China, see the 2 min video ► http://www.youtube.com/watch?v=1wImJC6xEoU.  In all nations, including USA, people near coal-fired plants often die of cancer at 45 or so, see the 10 min video ► http://www.youtube.com/watch?v=KZWAQ_3yoj8.  Coal pollution leads to cancer, asthma, autism (mercury), etc. Clean coal doesn't exist ► http://www.youtube.com/watch?v=_l0iqdfFyC0.

http://www.youtube.com/watch?v=Ps0DSihggio shows how tall buildings are built in 2 days.  The surface area of these buildings' exterior is far bigger than that of a solar farm on the building site, sometimes 50 times bigger.   http://landartgenerator.org/blagi/archives/127 shows it takes a small area to power the planet given the cheap 15% efficiency panels. The total urban areas represent about 2% of the global land surface. 60% of urban areas is roofs and pavements that could have solar panels embedded in them.  When we add the exterior of the buildings, we get 20 times more energy than we use today if we use the cheapest 15% efficiency panels.  We already have 40% efficiency panels and can reach 60% with IR.   There are panels that produce 20 times more energy per square foot, so that means 20 times less area needed ► http://goo.gl/vA3Oz.  More info at http://v3solar.com.  MIT also invented a solar array that can produce up to 20 times more power per surface area ► http://goo.gl/aacAs

The 3 min video http://www.youtube.com/watch?v=qqRp3XsZeFg shows how in the future we will be able to convert solar IR rays into electricity at night and during very cloudy days.  :)  With good battery storage, we can save the day time solar power for use at night and during eclipses.

Solar power + electric cars = no smog.  http://solarimpulse.com shows a solar plane.  Here are some more electric car news:

For a year, South Korea has already used roads to charge electric cars ► http://goo.gl/12IgSG.   Bhutan - with an income per capita lower than China or Russia and 7 times lower than United States - plans to shift all cars of its capital to electric Nissan Leafs and other modelshttp://goo.gl/Iql06c  Countries richer than Bhutan could aim to switch most big cities to electric cars.  China decided in November that 40% of new cars in Beijing will be hybrids or electric by 2017http://goo.gl/U7cjEe.  After rebates, one can buy a Leaf for 18K or lease it for $139/month at some dealers. In Europe they are testing a bus that can charge in 15 seconds ► http://goo.gl/9OT75.


some reasons for buying your next car electric:

7.  save money for noble purposes because electric cars are cheaper than many oil cars after the federal and state rebates:  in Colorado, you can buy a Nissan Leaf for only 15, 000, while in most other states for 18-21, 000.  A Smart EV costs only $12, 000 in Colorado, see http://smartusa.com.  Mitsubishi i-MieV is only $13, 000 in California and $10, 000 in Colorado ► http://www.evworld.com/news.cfm?rssid=31881
