30 year old solar panel produces as much electricity as when it was brand new, people still have solar panels from the 1970s operating perfectly on their roof. The actual lifetime of solar panels is 60-90 years. So, the actual solar power price per kwh is cheaper than wind and coal in many areas. The 3 cents/kwh price for solar (lowest ever on a power plant contract) assumes a 20 year lifespan for those panels, but if one keeps them for 60 years, the actual price is 1 cent/kwh, or about 5-8 times cheaper than coal :)

25 years is the warranty from manufacturers, but people can keep them for 90 years. Appliances come with a warranty of 2-5 years, but you can keep them 20-30 years.

For a detailed explanation of tremendous service to humanity done when you install solar panels or buy your next car electric, see https://plus.google.com/+AlexP/posts/Svx8uZ8Hk7A. You not only save the world, but your money too, since electricity is much cheaper than gasoline. :)

I have heard some disturbing reports over the past several years that some newer solar panels are having reliability issues. The main component (the silicon solar cell) of the solar panel isn't the issue, rather the sealing of these cells, and their interconnections inside the panel is. The suggestion has been that as the cost of solar panels dropped precipitously the industry was forced to cut manufacturing costs in every possible area. In some cases there seems to have been issues with sealants and cell interconnections that ultimately led to panel failures.

In earlier panels the overall cost was so high that saving a few pennies per watt was irrelevant, so the manufacturers were able to use higher quality materials.

+Mike Rotch Proper automated control of appliances and other building equipment can greatly reduce electricity demand, and so keep you warm at night without drawing more electricity. Essentially, one makes intelligent decisions about what devices to run and which to leave off.

More generally, solar thermal is far more cost effective for heating on a cold winter night than is PV and electric heaters. Solar thermal heating uses extremely inexpensive, well developed, sensible heat storage (essentially nothing but an insulated tank of water). Using a hybrid system of solar thermal heat, hot water and air conditioning, and then electricity for those few things that cannot be easily run with thermal energy, makes a much more cost effective solution than using low entropy electric energy for simple heat transfer.

2000-2010 drop in 2.5 micron particulate matter. Effects of particulate matter (generated by coal fired plants, cars, etc) on human health are much stronger as particles get below 2.5 microns and penetrate the lungs. Particles between 0.3 and 1 enter the lung air sacs, those between 1 and 2 microns enter the lung bronchi - and these particles can be HEAVY METALS (Arsenic, Mercury from Coal Fired Plants, etc). Coal and car smog 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, not just Alzheimer, asthma, lung cancer, heart disease. Also, http://www.news.cornell.edu/stories/2007/08/pollution-causes-40-percent-deaths-worldwide-study-finds explains that 40% of deaths are due to pollution. Smog kills billions earlier than their normal time. Coal fired plants generate most human emissions of mercury and arsenic in the air.

In 2011 only 3.5% of 15 year olds in the Los Angeles Metro area had significant lung deficits, compared to 8% of 15 year olds in 1998. This is a result of ever tightening air regulations in California, which benefit public health (air pollution was shown to cause autism, heart disease, asthma, lung cancer, etc). With 40% of US electric cars in California, if the electric car trend continues, California will have the cleanest air in the nation one day. Car smog gets into the lungs and lodges up there, effectively destroying the lungs and preventing lung growth in children.

Air Pollution and Alzheimer Disease explanation from University of Rochesterhttps://www.urmc.rochester.edu/labs/elder-lab/projects/air_pollution_and_alzheimers_disease

http://hsnewsbeat.uw.edu/story/study-shows-how-air-pollution-fosters-heart-disease is a Washington University study showing what has been known for decades: car pollution as 2.5 micron particulate matter leads to heart disease. For example if you look at city-data.com and type your city, then Ctrl F to find "PM2.5" you will see the 2013 levels of ParticulateMatter2.5 which are Mountain View 11.3 (Google headquarters), New York 9.03, San Francisco 10.2, Sacramento 9.85, Redding, CA 6.07, Miami (Florida) 6.55, Houston 12.3, Seattle 9.29, Washington DC 11.4, Boston 9.07, Pittsburgh 9.71, Chicago 10.8, 17.7 in Beverly Hills, 17.4 in Santa Monica, 15.9 in Gardena, Manhattan Beach 16.4, Torrance 15.5, San Diego 11.2, Carlsbad 10, Malibu 9.40, Santa Barbara 9.65, Los Angeles 18.9, San Luis Obispo 7.11, I.e. LA area has high values compared to Northern California, San Diego and most of the big US cities.

The US average is 9.4. Beijing often reaches 250 (sometimes even 1000, 100 times above US average) - 10 times the 25 World Health Organization limit for safety. The 2013 Beijing average was 90.

There is no better "driving" karma than driving an electric car, especially if you drive more than 300 miles a month. Or some kind of plug in hybrid at least, short distances electric, longer gas. If one cannot drive electric for whatever reason, solar panels or going vegan can offset more than an electric car driven a lot. Solar panels a lot more than going vegan, if a big system in a sunny area.

Deep geothermal energy
#Geothermal #power #plants and #heating networks use natural water resources from deep water and rock strata. In terms of the efficiency of the plants, the #drilling #costs and the premature wear and replacement of the feed #pumps have previously made a considerable impact on the balance sheet. The BINE-Projektinfo brochure "Developing robust pumps for geothermal energy" presents modified submersible centrifugal pumps that are specifically adapted to the requirements of deep geothermal energy.

Systems for using deep geothermal energy need special pump systems. These are up to 36 meters long and weigh eight tonnes. They must be able to withstand high temperatures and high flow rates, as...

#Biochar Based #MicrobialFuelCell #MFC for Enhanced #WastewaterTreatment and #Nutrient Recovery #sustainability

Waste-wood derived biochar was evaluated for the first time as both an anode and cathode material, simultaneously, in an overflow style microbial fuel cell (MFC) using actual industrial wastewater. Results show that the average chemical oxygen demand (COD) removal was 95% with a reduction rate of 0.53 kg·COD·m−1·d−1 in closed operation mode. The ammonia and phosphorous reductions from wastewater was 73% and 88%, respectively. Stable power production was observed with a peak power density measured at 6 W/m3. Preliminary contributions of physical, biological, and electrochemical COD removals were evaluated, and the results show such combined mechanisms give BC an advantage for MFC applications. Nutrient recovery data showed high levels of macronutrients adsorbed onto the spent biochar electrodes, and phosphorus concentration increased from 0.16 g·kg−1 in raw BC to up to 1.9 g·kg−1 in the cathode. These findings highlight the use of biochar as electrodes in MFCs to facilitate simultaneous wastewater treatment and power production with additional agronomic benefits.

self-driving mode on a Tesla electric car
 
2 min video about the Tesla Model X Autopilot self-driving mode, a form of super-advanced cruising with the car knowing how to change lanes, slow down, etc all on its own. Tesla raised $1.7 billion to make half a million Model 3 cars a year in 2018 and they all will have Autopilot :)

Tesla Model 3 got 0.4 million reservations so far; it had reached within 7 days pre-orders worth 14 billion dollars, making it the most successful product launch ever, way more successful than the Apple iPhone 6. Model 3 will be 25K for everyone after the federal and California incentives if they extend those incentives more after elections. In Colorado it will be 21.5k due to the largest electric rebate in the nation, but all states get 7.5K tax credit, so 27.5k at the most. FREE CHARGING FOR LIFE AT supercharger stations. The only car company offering a cheap 215 mile range sedan that makes only electric cars to save the planet from carcinogenic smog and climate change. Tesla is the best.
