Parked RVs and solar panels drive up surface temperatures?

“It turns out parked RVs and solar panels may have artificially driven up temperature readings at nearby, poorly cited thermometers used by government officials at Death Valley National Park in California, according to meteorologist and science blogger Anthony Watts.” click here

Another solar energy company scam?

“Three former SolarCity employees have reportedly sued both SolarCity and its parent company Tesla, alleging that the solar panel manufacturer took part in serious corporate misbehavior. According to the former employees, SolarCity approved the creation of “fake sales accounts” which resulted in “unjustified bonuses” for employees and caused an “unreasonably high valuation of SolarCity.” The former employees also allege that they faced severe harassment and discrimination leading up to their one year tenure ending in 2017.” click here

Solar panel waste is toxic, not easily recycled

“The problem of solar panel disposal “will explode with full force in two or three decades and wreck the environment” because it “is a huge amount of waste and they are not easy to recycle.” “ click here

California new home solar panel mandate a “feel good” action with no impact on climate changes

“California will mandate solar panels on new homes out of concern for climate change, a policy that will raise prices in the most expensive home market in the country and does little to decrease the state’s carbon footprint.” click here

100 percent renewable energy is unsustainable

Matthew R. Shaner, Steven J. Davis, Nathan S. Lewis, Ken Caldeira. Geophysical constraints on the reliability of solar and wind power in the United States. Energy Environ. Sci., 2018, doi: 10.1039/C7EE03029K

We analyze 36 years of global, hourly weather data (1980–2015) to quantify the covariability of solar and wind resources as a function of time and location, over multi-decadal time scales and up to continental length scales. Assuming minimal excess generation, lossless transmission, and no other generation sources, the analysis indicates that wind-heavy or solar-heavy U.S.-scale power generation portfolios could in principle provide ∼80% of recent total annual U.S. electricity demand. However, to reliably meet 100% of total annual electricity demand, seasonal cycles and unpredictable weather events require several weeks’ worth of energy storage and/or the installation of much more capacity of solar and wind power than is routinely necessary to meet peak demand. To obtain ∼80% reliability, solar-heavy wind/solar generation mixes require sufficient energy storage to overcome the daily solar cycle, whereas wind-heavy wind/solar generation mixes require continental-scale transmission to exploit the geographic diversity of wind. Policy and planning aimed at providing a reliable electricity supply must therefore rigorously consider constraints associated with the geophysical variability of the solar and wind resource—even over continental scales.

Expect Renewables to Increase Energy Prices (in some cases to unaffordable levels).

“The one thing we know for sure is that even though sunlight and moving air is free, there is no country on Earth with lots of solar and wind power and cheap electricity.” click here

Solar Power Snow Job, United Kingdom

“The renewable lobby would like you to believe that solar power is an important part of our future energy strategy. But they don’t tell you just how little power is produced during winter months, at the time when demand is at its peak.” click here
