“Exactly how much of a plastic bottle can be used after its been used?”

In the United States, plastic water bottles can be found everywhere. Whether it be in the supermarket for grocery shopping or on the picnic blanket for plying. However, the plastic that makes these bottles pose numerous threats to the environment. This can be mitigated through recycling. But exactly how much of the material be recycled? Well, if the bottle is made from a polymer known as PET, then approximately 62% of it can be recovered! This is How Much of a Plastic Bottle Can Be Recycled.

“What are the advantages of utility-scale solar over rooftop?”

Utility-scale solar often competes with rooftop solar. Although we here at Isaac Science Blog believe in the value of both, we also like to inform of the costs and benefits. The main advantages of utility-scale solar are that it is cheaper and can be put over brownfields. These are the Advantages of Utility-Scale Solar over Rooftop Solar.

“How can governments use policy to increase the amount of storage on the grid?”

`Energy storage is one of the hottest things in the energy world right now. But despite its seemingly invincible potential, it still needs government action to come online. One clever way to do this is to make a policy stipulating that utilities need to adopt a certain amount of energy storage through an Energy Storage Mandate. This is commonly implemented in California and other governments to meet their carbon neutrality goals.

“Why is offshore wind in the U.S having logistic problems?”

Offshore wind in the United States is expanding at a rapid pace, particularly in the Northeast. However, since offshore wind turbines tend to extremely large in nature, it takes a large amount of transportation infrastructure such as cranes and heavy trucks for transportation logistics. Due to the limited supply of these components, these projects face the possibility of being stalled. This is Why Offshore Wind in the U.S is Facing Logistic Bottlenecks.

“How does cost scale with physical production?”

Cost tends to scale with increased production of a particular element. However, the amount of cost of each item might get larger or smaller! The rate of change of each element to increased production is known as the Returns to Scale. This information is vital for the renewable energy industry, as the optimal deployment size will depend on the best return to scale.

“Why do some facilities seem to obtain less power than they receive and how are they penalized in a tariff?”

Every facility connected to the grid can receive energy. But the amount that it receives versus what was apparently sent is known as the Power Factor Tariff. The lower the power factor tariff, the more generators and transformers, and other power infrastructure is needed to keep the system running. Since this increases the amount of upkeep needed, utilities implement a Power Factor Tariff to penalize users who draw too much from the grid.

“How can we design a two-part tariff specifically catered to the maximum demand of a system?”

Two-part tariffs are great for controlling system-level energy use. But sometimes we would like to focus it on controlling the maximum demand for energy use. We can use something called a Maximum Demand Tariff which not only charges in proportion to energy used but levels an extra tariff based on the max power they drew for the given time period.

“How can we have an energy tariff that charges both at a fixed and proportional rate?”

Energy tariffs come in all shapes and sizes. One of the most interesting ones is those that not only charge at a proportional rate but also at a fixed rate. This Two-Part Tariff can be used in the case of optimization for grid network loads.

“How can we make an electricity tariff that becomes progressively cheaper as you use more energy?”

Charging less for increased energy consumption makes sense in many cases such as incentivizing renewable energy production. One way to accomplish this is to use a tariff structure in which energy consumption amounts are divided into discrete blocks and each succeeding block of energy used is cheaper. These Block Rate Tariffs can be implemented by utilities to accomplish their infrastructure and market goals.
