    It was a solar experiment that seemed ingenious in its simplicity: fill a road with photovoltaic panels and let them passively soak up the rays as cars drive harmlessly above. The idea has been tried a few times, notably in rural France in 2016 with what was christened the "Wattway." Three years later, even the most optimistic supporters have deemed the Wattway a failure.

    If the official definitions of renewable energy were logical, renewable energy would be defined as energy that does not emit CO2 and that is not using a resource in danger of running out anytime soon. But the definitions written into the laws of many states are not logical. Hydroelectric energy is mostly banned because the environmental movement hates dams. Nuclear is banned ... Both nuclear and hydro don't emit CO2. Hydro doesn't need fuel. Nuclear fuel is cheap and plentiful. A large number of prominent global warming activists, such as James Hansen, Michael Shellenberger, and Stewart Brand have declared that...

    The left just loves to tout "renewable energy" as the clean, green panacea, something that will save the earth. Just look at the foremost proponent of this, California's Gov. Gavin Newsom: On day one, I will issue a directive putting California on a clear path to 100% renewable energy. It’s achievable and it’s necessary. Frankly, I think we can surpass our 100% goal by positioning California as a net exporter of energy to other states and nations. It’s a money maker for us and the natural next step in our global leadership — a classic example of California innovation. Under the leadership...

    Stunning new images snapped in orbit show LightSail 2s solar sail outstretched and ready to take on the next phase of its mission. The Planetary Society announced that the 18-foot-wide Mylar sail had successfully deployed earlier this week, following a late-June launch atop a SpaceX Falcon 9 rocket. Its just one five-thousandth of an inch thick, or about the width of a human hair. The milestone could pave the way for lower-cost spacecraft propulsion, allowing small craft to be driven by sunlight.
  • Carbon-Free Power: Solar versus Nuclear: It's No Contest

    American Thinker ^ | 07/12/2019 | Wallace Manheimer
    There are two possible sources of carbon-free power available today: solar power and nuclear power. Solar power includes solar photovoltaic (converting sunlight directly into electrical power) and solar thermal (heating a fluid with sunlight and converting the heat to electricity). Solar power has received hundreds of billions of dollars in subsidies and research grants in the United States alone, and perhaps as much as a trillion worldwide over the past 30 years. For that investment, solar contributes roughly 1% of the world's total power. So which is better, solar or nuclear? While it is impossible to provide a definitive answer...

    In the 1970s, Americans were told we were in a global cooling crisis and if something wasnt done, wed enter a new ice age. When that didnt happen, a few decades later we were told that entire nations could be wiped off the face of the Earth by rising sea levels if the global warming trend was not reversed by the year 2000. Despite the consistent failure of these apocalyptic warnings, that hasnt stopped climate change alarmism. Were now being told we only have 12 years to combat climate change, and the solution is to fundamentally dismantle the system of...
  • What It Will Take for the Wind and Solar Industries to Collapse

    American Thinker ^ | 07/09/2019 | Norman Rogers
    The solar electricity industry is dependent on federal government subsidies for building new capacity. The subsidy consists of a 30% tax credit and the use of a tax scheme called tax equity finance. These subsidies are delivered during the first five years. For wind, there is subsidy during the first five to ten years resulting from tax equity finance. There is also a production subsidy that lasts for the first ten years. The other subsidy for wind and solar, not often characterized as a subsidy, is state renewable portfolio laws, or quotas, that require that an increasing portion of a...

    Abstract:Recently discovered long-term oscillations of the solar background magnetic field associated with double dynamo waves generated in inner and outer layers of the Sun indicate that the solar activity is heading in the next three decades (2019–2055) to a Modern grand minimum similar to Maunder one. On the other hand, a reconstruction of solar total irradiance suggests that since the Maunder minimum there is an increase in the cycle-averaged total solar irradiance (TSI) by a value of about 1–1.5 Wm−2 closely correlated with an increase of the baseline (average) terrestrial temperature. In order to understand these two opposite trends, we...

    What's not to like about this concept: high-efficiency solar cells gifting electric cars with mileage. Bertel Schmitt, The Drive, said, "The solar roof could morph from mostly a marketing-device to a helpful feature." He noted that, referring to plug-ins, "On a fair-weather day, the juice would be provided by the sun, a big improvement especially for people who don't have their own garage."Toyota has ambitions over the concept and is to start testing an onboard solar recharging system where the hood, the roof, and back are covered with cells. The solar roof can charge while the car is on the...

    A transition to renewable energy sources is a likely scenario if the anti-fossil establishment manages to persuade lawmakers to implement their green energy policies.Given the high probability, and the transitions already happening in some countries, it is high-time for us to inspect the functional and operational efficiency of renewable sources, especially the highly acclaimed solar installations.The Renewable CrazeThe so called craze about renewable energy is a myth. The top users of fossil fuels are still actively generating power from fossil fuel and are also helping other countries to develop fossil fuel technology.The major reasons for this are the high cost...

    The Ohio state legislature is considering HB 6, the Ohio Clean Air Programa poorly named bill that will cost Ohio families money and harm clean energy job growth, all the while failing to improve air quality. Most families worry about paying their bills, finding good jobs, and protecting the health of loved ones. HB 6 makes it harder for Ohio families to succeed on all these fronts it raises electricity bills for Ohio families and businesses, does nothing to abate respiratory illness causing air pollution, and makes it virtually impossible to build new, job-creating clean energy projects in the state....

    ...why is its outer atmosphere hotter than its fiery surface? University of Michigan researchers believe they have the answer, and hope to prove it with help from NASA's Parker Solar Probe. In roughly two years, the probe will be the first manmade craft to enter the zone surrounding the sun where heating looks fundamentally different than what has previously been seen in space. This will allow them to test their theory that the heating is due to small magnetic waves travelling back and forth within the zone... Such high temperatures cause the solar atmosphere to swell to many times the...

    Eruptions from the face of our star are called prominences and cause vast amounts of superhot gas to shoot into space, often forming beautiful loops on the solar surface. During the solar minimum, the number of flares and sunspots is dramatically reduced. When the sun leaps back from its minimum after roughly 11 years, were likely to see more and more ferocious explosions on the sun. Nasa warned: After our Sun passes the current Solar Minimum, solar activity like eruptive prominences are expected to become more common over the next few years. The space agency has just released dramatic pictures...

    Interfacial evaporators are made of thin materials that float on saline water. Absorbing solar heat on top, the evaporators continuously pull up the saline water from below and convert it to steam on their top surface, leaving behind the salt, explains Hu... However, over time salt can build up on this evaporative surface, gradually degrading performance until it is removed... Hu and his colleagues minimized the need for this maintenance with a device made out of basswood that exploits the wood's natural structure of the micron-wide channels that carry water and nutrients up the tree. The researchers supplement these natural...

    U.S. solar energy company SunEdison Inc, whose aggressive acquisition strategy has saddled it with almost $12 billion of debt, is at "substantial risk" of bankruptcy, one of its two publicly listed units warned on Tuesday. A bankruptcy would rank among the largest involving a non-financial company in the past 10 years, according to bankruptcydata.com. SunEdison declined to comment. SunEdison's shares - already reeling from a Wall Street Journal report on Monday that the company was being investigated for overstating its cash position - fell as much as 60 percent to a record low of 50 cents.

    Federal officials and energy experts offered their most blunt assessment to date regarding the ongoing vulnerability of the U.S. power grid, telling a Senate committee that solar-generated attacks alone cost $10 billion a year. In testimony before the Senate Homeland Security and Governmental Operations Committee, the officials noted that the attacks are growing and pose a substantial, long-term risk to a vulnerable power grid. They warned that a catastrophic failure would cut off electricity to millions of Americans, probably for months at a time, causing untold damage and social chaos, adding that the grid is an easy target for solar,...

    FULL TITLE: Spotsylvania, Va., Residents Outraged Over Massive Solar Plant Proposal, About Half the Size of Manhattan More than 300 residents of rural Spotsylvania County, Virginia gathered at the Spotsylvania Courthouse on Dec. 5 to protest plans for a massive solar energy plant half the size of Manhattan -- which would be built close to residential areas and the historic sites of three Civil War battlefields. In addition, none of the energy from the plant would go to the Spotsylvania community.
