Why Transmission Cables Need to be Lightweight
“Why do transmission cables need to be lightweight?”
Transmission cables are what connects the modern grid together. And one of their most important properties is their weight. The lighter their weight, the weaker their sag. This is Why Transmission Cables Need to be Lightweight.
“How can we have hyper distributed electricity generation?”
With the advent of climate change, distributed energy resources are proliferating at ever-expanding rates. However, sometimes this decentralized generation must be taken to the utmost levels to ensure infrastructure vitality. Anything of less than or equal to 500 kW of distributed energy generation is known as Dispersed Generation. An Example of dispersed generation includes rooftop photovoltaics.
Why the Increasing Frequency of Fires Will Threat Energy Resilience
“How will the increased frequency of fires make us less energy resilient?”
The climate is changing. As temperatures get higher, the natural world is being thrown out of balance, and this includes dangerous fires such the one seen in Northern California. As these fires become more frequent, they will threaten power lines and energy generation sources. As a result, The Increasing Frequency of Fires Will Threat Energy Resilience.
“What is energy that can be sent off at any time?”
Energy can be generated by many different sources, but they will have different properties. Some energy sources can be turned on and off and adjusted to the utility operator’s whim. This is known as Dispatchable Generation and can be supplied by energy sources such as geothermal.
Residential and Commercial Installed Solar PV Prices Still Falling in the U.S
“Solar prices are still falling in the U.S!”
Small news update. According to a study by Lawrence Berkeley National Lab, the price of a median-sized installed solar PV has declined around 5% from the first half of 2017 to the second half. This and other information shows that Residential and Commercial Installed Solar PV Prices Still Falling in the U.S.

Negative Energy Pricing
“Can energy become so cheap that prices become negative?”
The more supply relative to demand that cheaper a product is. And energy is no exception to the rule. States such as Germany, California, and Hawaii are now generating so much energy from Distributed Energy Resources and conventional power during low period times that electricity prices are going negative! To avoid great imbalances, these areas are now selling their energy to neighboring states to create grid balance.
How Could Distributed Energy Resources Disrupt Utilities?
“Will big utilities face a compromised future from distributed energy resources?”
Ever since the dawn of the grid utility companies have reigned supreme. But with the advent of distributed energy resources, this all might change. Now that many individuals are achieving grid defection, they no longer have any use for a utility. If the cost of battery storage collapses and energy efficiency has a paradigm shift, this could spell massive disruption for these traditional companies. They might even have to watch out for their survival.
