green transportation solutions

Public transportation has the potential to transform traditional cities into sustainable paragons. When comparing the carbon footprint of public transit to that of single-passenger cars, the former carries a myriad of benefits. These include reduced fuel consumption, improved air quality, decreased traffic congestion and cost savings for commuters.

Public transportation has the potential to be a key player in the future sustainability of urban areas. Cities across the United States are working to find green transportation solutions to improve an outdated system. These initiatives include switching to electric buses, improving walkability in communities and making policy changes.

Here are five green transportation solutions to be on the lookout for in the future:

10 Hydrogen Fuel Cells Advantages and Disadvantages

May 22, 2020
hydrogen fuel cells advantages and disadvantages

We are most familiar with hydrogen as an energy source in several organic compounds. These compounds are referred to as hydrocarbons and help form natural gas, propane and gasoline. Hydrogen fuel cell technology, on the other hand, is a process that transforms chemical energy into electrical. Because of its potential as a clean source of power, it has become an alternative to combustion-based systems.

Most hydrogen forms by separating it from natural gas, though scientists are working on other innovative ways of accomplishing this. One method of hydrogen gas extraction is through electrolysis. This process requires running an electric current through water, resulting in the separation of hydrogen and oxygen atoms. Unfortunately, this method is not cheap and involves carbon-intensive energy sources like oil and natural gas. 

Hydrogen fuel cell technology may change the way we power vehicles in the future. However, it also presents a few key challenges. Let’s examine hydrogen fuel cells’ advantages and disadvantages and what they mean for the future development of this energy source.

Sustainable Transportation: Electric Car Emissions vs. Gas

May 18, 2020
electric car emissions vs gas

Electric vehicles (EVs) and renewable energy are shaking up the transportation industry. As consumers look for more sustainable solutions, automakers seek to fill the demand with cost-effective and energy-efficient alternatives to gas-powered vehicles. Additionally, as the global economy shifts away from a fossil fuel-dependent model, more companies are looking for ways to reduce emissions.

Comparing electric car emissions vs. gas requires looking at direct and lifecycle emissions. The former measures the amount of pollution associated with the vehicle’s tailpipe and fueling process. The latter accounts for the car’s production, use and disposal.

The mining and processing of car batteries for EVs is much more energy-intensive than the manufacturing of gas-powered vehicles. However, the total emissions produced by electric vehicles during their lifetime is significantly less than gas-powered cars. As the auto industry heads in a more sustainable direction, electric vehicles will play a vital role in the future of transportation.

Sustainability and Efficiency of Nuclear Energy vs. Fossil Fuels

May 4, 2020
nuclear vs. fossil fuels

Nuclear energy comes from the energy stored inside atoms — namely uranium atoms. These repeatedly split and merge in a process called nuclear fission. Fossil fuels, on the other hand, produce electricity and energy through burning resources like coal, gas and oil. 

Currently, nuclear power provides about 10% of the world’s electricity, while fossil fuels produce roughly 80%. But which is more sustainable? And is one more efficient than the other?

Key Advantages and Disadvantages of Nuclear Energy

May 1, 2020
advantages and disadvantages of nuclear energy

When you hear the words “nuclear energy,” you might think of a radioactive core, a steaming power plant or maybe even nuclear bombs like the one dropped on Hiroshima. While these are all accurate representations of nuclear energy, they generally come with negative connotations. However, nuclear energy also presents a number of advantages. Below, we’ll discuss the advantages and disadvantages of nuclear energy and what the future of energy may look like.

Advantages of Nuclear Energy

Nuclear energy often comes under fire for being dangerous and disadvantageous, especially if something goes wrong. However, the only time people typically hear about nuclear plants is when something does, in fact, go awry. What most of the public doesn’t know is that there are actually several advantages to this type of energy.

Renewable Energy vs. Nuclear: Which is a More Viable Option

April 29, 2020
renewable energy vs nuclear

As concerns about the global impacts of climate change grow, the need for clean energy has become increasingly clear. The current rates of fossil fuel consumption and greenhouse gas emissions must dramatically reduce if we hope to keep climate change’s effects to a minimum. Thankfully, there are several options for generating electricity without pumping carbon dioxide into the atmosphere — and many are already in use.

Nuclear power plants and renewable energy generators like wind farms and hydroelectric dams currently provide a combined 19% of the power consumed in the United States. That number is even higher in other countries. Expanding nuclear and renewable energy programs can combat climate change by reducing reliance on fossil fuels.

But between renewable energy and nuclear, which is the more viable option? Let’s compare these two types of energy generation below.
