QUICK NEWS, August 29: The History Of Climate Change; To Buy Or To Finance Solar, That Is The Question; Wind Fits The National Power Mix
The History Of Climate Change Humans Kickstarted Climate Change Nearly 200 Years Earlier Than Scientists Thought
Jasmine Solana, August 28, 2016 (Futurism)
“…Most experts agree that human activity has played a major role in making climate change happen, but the consensus is that it is a fairly recent trend. New research, however, has found…that global warming began during the early stages of the Industrial Revolution and is first detectable in the Arctic and tropical oceans around the 1830s…[D]irect measurements of climate were rare before the 1900s, which was why anthropogenic climate change was generally talked about as a 20th century phenomenon. But [using 500 years of data on tree rings, corals, cave decorations, and ice cores form a natural archive of the Earth’s temperatures throughout history], along with thousands of years of climate model simulations, [Early onset of industrial-era warming across the oceans and continents] pinpointed the early onset of warming to around the 1830s, and found the early warming was attributed to rising greenhouse gas levels…” click here for more
To Buy Or To Finance Solar, That Is The Question Breaking Down Solar Energy Options
Cathy Allen, August 26, 2016 (AFRO)
“…Solar power systems can cost $15,000 to $30,000 before any rebates and incentives. Once installed, the owners receive rebates, tax credits and/or state renewable incentives that can reduce the total cost by 50 percent. Most solar installation companies will manage all the paperwork and adjust the purchase price to reflect the net amount…[Owners are responsible for maintenance of the system but the] equipment is very durable [comes with warrantees] and can withstand the elements…[Maintenance is primarily] cleaning panels…Many banks are now offering tailored solar systems loans to homeowners with FICO scores 640 or above…[with 10-to-20-year terms and] interest rates ranging from 3 percent to 8 percent…Typically, a solar system will save between 40 percent to 70 percent on electricity over about 20 to 25 years…[With leasing and power purchase agreements (PPA)] the solar company owns and maintains the system. There is little to zero cost for installation [but electricity savings are only] 10 percent to 30 percent…[and the homeowner does] not get the benefits of tax credits or renewable incentives or rebates…[Using solar energy through any financial arrangement is a step forward] in protecting our wallets and the environment.” click here for more
Wind Fits The National Power Mix Wind power keeps the lights on and lowers costs
Michael Goggin, August 26, 2016 (The Hill)
“…An electricity grid drawing power from different types of generation protects consumers against both fuel price fluctuations and outages at specific plants…[W]ind energy has proven critical to maintaining a cost-effective, reliable electric grid. During 2014’s Polar Vortex weather event, demand skyrocketed as buildings ran their furnaces at full output during the extreme cold. Supply was also reduced, as the frigid temperatures unexpectedly knocked many conventional power plants offline, in some cases due to fuel supply constraints…[W]ind turbines kept turning…[and] saved consumers across the Great Lakes and Mid-Atlantic regions over $1 billion in just two days…[Technological advances now allow wind turbines to reach stronger, steadier winds and generate 90% of the time and this] number increases even further when grid operators aggregate the output of all wind plants, and all sources of supply and demand, over large regions…Coal, nuclear and natural gas plants don’t generate electricity 100 percent of the time either…[and] often experience outages from unforeseen events. When these things happen, other plants on the electric grid [like wind installations] step in, illustrating the importance of a diversified energy mix…Wind power’s greatest contribution to a reliable, diverse electricity mix is its ability to produce energy with no fuel cost or fuel price risk…while creating cleaner air.” click here for more
