How to Properly Dispose of Batteries in the United States
“How should one properly dispose of batteries in the United States?”
Although incredibly commonplace, batteries are also some of the most toxic devices manufactured today. Their corrosive electrolytes and elements make them dangerous to throw away without any consideration. For this reason, some batteries must be disposed of in a special manner. If you live in the U.S in a state that is not California, all batteries except for watch batteries can be disposed of in the trash. If you would like to recycle a single-use battery, you must contact a local solid waste district to learn if there is a nearby collection program or upcoming event, find a battery recycling center, or find a mail-in battery recycling program. This is How to Properly Dispose of Batteries in the United States.
Why Seasonal Energy Storage is Necessary for Large-Scale Penetration of Renewables
“Why should we be able to store energy for months?”
Energy storage is the biggest bottleneck in the deployment of renewable energy. Not only are we currently limited in the amount we can store, but also the time, as decay occurs the longer it is stored. And with the deeper penetration of renewables, energy will have to be stored for longer durations, so that charge can be stored during the sunny summer months and extracted in the dark winter ones. This is Why Seasonal Energy Storage is Necessary for Large-Scale Penetration of Renewables.
Distributed Energy Storage
“How can we best optimize energy storage?”
If you ask a renewable energy expert what is one of the biggest hurdles facing the proliferation of solar and wind, chances are you’ll hear energy storage. Storing energy requires a massive infrastructure investment, whether it be in batteries or other mechanisms. However, for the most optimum approach, all methods should be combined to create a Distributed Energy Storage solution. This way the maximum amount of energy can be stored for later use.

“What is the largest possible scale of energy storage with modern day engineering?”
Companies such as Tesla Motors are investing in energy storage like there is no tomorrow. The current frontier is Gigawatt-Hour-Scale Storage. Just to put things into perspective, one gigawatt-hour is enough to power the average California home for over 92 years!
How Tesla’s Big Australian Battery Might Become a Monopoly
“Why might there be no more ancillary service players in South Australia after Tesla?”
California based Tesla Motors recently made headlines by supplying 100 MW of their batteries to the South Australian Hornsdale Power Reserve to help control ancillary services. This project was so efficient that it absorbed 55 percent of all FCAS revenues in South Australia as well as cutting ancillary services pricing by 90 percent. Analysts say that this has been so efficient that it is possible that there will be no more room for competition in South Australia.
MPPT Charge Controllers
“What is the most efficient solar tracker?”
PWM Solar Charge Controllers are definitely a step up from On/Off Solar Controllers. However, they’re definitely not the most efficient models. MPPT Controllers (Maximum Power Point) can maximize the output by changing the current and voltage delivered while doing the best to keep power constant. Because of this, they are the most highly valued systems on the market.
“Can Solar Plus Storage make the grid obsolete?”
In the 20th century, back when we were reliant on massive power plants to produce energy, if you wanted to have electricity in your home then you had to sign up an electrical utility. But with the advent of Solar Plus Storage Systems, this might become a thing of the past. Now that people can not only generate but store their own electricity at their home, there is no longer a need to be attached to the grid. In some cases, it’s actually cheaper to become off-grid! As a result, many people are undergoing grid defection and turning to generate their own electricity.
