“How do utility companies purchase electricity generation?”

 

Utility companies are responsible for transmitting electricity. However, they do not always own generation facilities. Instead, they may purchase it on a competitive platform known as a wholesale electricity market. This decoupling of electrical generation and transmission can create a multitude of opportunities for Power Purchase Agreements.

“How can grid defection increase infrastructure resiliency to climate change?”

 

Grid-islanded systems are typically thought of as expensive alternatives to their grid-depended counterparts. But with the advent of ever-increasing storms and floods induced by climate change, their constant reliability will make them a more reliable alternative. Since they can provide power in the case of natural disasters, they can provide extra resilience to communities such as Puerto Rico who experienced a grid shutdown from Hurricane Maria.

“How could trimming trees help prevent blackouts?”

 

Grid failure happens all the time. But one of the most common causes actually stems from something very simple, trees! Tree foliage produces an area that is sensitive to burning and is also liable to falling down, crushing distribution. By taking away some of this foliage, some of this resiliency liability. This is How Tree Trimmings Could Help Build Power Resilience.

“How can engineering simulations save companies a lot of money?”

 

Before the ascent of computers, most engineering modeling had to be done with physical experiments. These were arduous, costly, and prone to failure. But with the invention of simulation, companies can now simulate their designs’ performance without having to actually build it. This is How Engineering Simulation Can Save Companies a lot of Money.

“What happens when power is provided to all four wheels of a car at the same time?”

 

Different driving conditions will need different modes. When a vehicle is off-road in a low-traction environment, the wheels will need to receive a large amount of power. This can be solved using a Four-wheel Drive in which all wheels of a car are powered evenly and simultaneously. Although four drives are great for off-road conditions, the immense power can wear out tires on a normal road.

How can community-sourced energy be cheaper and greener?

 

There is a revolution brewing in the renewable energy world. While in the past residents and businesses were tied to one electric utility based on their geographic area, organizations known as Community Choice Aggregators are starting to sprout up and challenge this. Community choice aggregators or CCAs are non-profit organizations that procure power generation and deliver it to customers through a utility’s transmission lines. Since these do not operate for investors and only need to pay for energy and staff, they can give their customers better rates than traditional electricity service and focus on particular resources. To illustrate, just look at the CCA San Jose Clean Energy. Even though their energy portfolio is 45% Renewable Energy/80% carbon-free, they sell energy at rates 1% lower than the standard San Francisco Bay Area PG&E service which is 33% Renewable Energy/78% carbon-free. This is How Community Choice Aggregators Can Offer Cleaner Energy at Lower Rates!

“Why is wave energy really helpful for island nations?”

 

Island nations are strapped when it comes to energy resources. Their small land area limits the potential for distributed energy resources and centralized power plants pose a large resilience risk and monetary expense. However, there might be one form of power that can be a game changer. Since islands are surrounded by water, the can harvest the kinetic energy from the waves crashing onto their beaches. Complimenting this with other renewables, island nations can achieve true self-sufficiency. This is How Wave Energy Can Help Island Nations.
