“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.

“How can we hook up two asynchronous power connections?”

 

Different power grids might operate at different frequencies. And they might also cover different geographic regions that offer different but useful resources. They can be hooked up together at an HVDC substation using something called a Back-to-back Connection.

“How can a company provide energy solutions?”

 

Energy is just as dependent on economics as physics. As a result, electricity needs to be generated and distributed through a variety of manners. One of through an Energy Service Company, a commercial or non-profit organization that provides a vast array of energy services whether it be service implementation or retrofitting.

How Energy Storage Can Increase Carbon Emissions

“How can energy storage increase carbon emissions?”

 

Numerous renewable energy proponents around the world are promoting energy storage as the solution to intermittency. However, if not planned out carefully, energy storage can be very unsustainable. This is because energy storage can store any type of energy, clean or not, with a preference for cheaper inputs. This means that cheaper overnight coal might be used for storage and then placed against more expensive natural gas or solar. In addition, energy is lost during storage, so the net efficiency drops as well. This is How Energy Storage Can Increase Carbon Emissions.

“How can an economy not contribute to climate change?”

 

Traditionally, economies have grown in tandem with carbon emissions. But with the advent of modern-day extreme climate change this is no longer feasible. To solve this, nations will have to adopt Carbon Neutral Economies in which all sectors have slashed their emissions to zero. The transition to a low carbon economy could yield enormous economic growth as well as inequality easing. Multiple governments around the world are committed to this action, with California’s 2045 and the EU’s 2050 initiatives as examples.
