Clean Tech applications: Ride share and carpooling

Remember how hitchhiking was an accepted mode of transit in America years ago? Well, now we have ride sharing. With approximately ¾ of commuters driving alone to work in the U.S. every weekday, alternative transportation modes bring many benefits.

Ride sharing is a simple way to save money, reduce one’s carbon footprint, provide opportunities to network and expand one’s contacts, reduce driving stress, as well as pleasant. Find friends, neighbors, and co-workers who are traveling the same way you are – for school, work, events or leisure – and share a ride.

There are several variations of sharing transit: carpooling, where pool members use their own private cars. Ride-share also refers to members jointly share the costs of a rented car; or sharing a ride in a hired vehicle with a hired driver, like a shared taxi, shuttle, vanpools, etc.... read more

Do electric cars really help the environment? Are they 'green'?

Are hybrid and electric vehicles batteries a Green alternative or add hazardous chemicals to our landfills?

Visiting the West-Coast Green conference in San Francisco this past week confirmed the feel-good and coolness of electric vehicles. Photo from hybridcars.com: Photo from hybridcars.comPhoto from hybridcars.com: Photo from hybridcars.com

I would definitely be a happy camper if I win the electric bike or electric tricycle raffle!... read more

New developments in electric vehicle batteries

Safety concerns in the auto industry: electric vehicle (EV) batteries are going through a change.

The emergence of small lightweight and long-running lithium-based batteries has helped propel many technological products in several industries. Lithium-based batteries are used in portable electronic devices, such as laptops, cell phones, MP3 players, iPod, cameras, as well as, implantable electronic medical devices, and in electric vehicles.

Some environmentally conscience people are concerned that a hybrid bliss might turn into a toxic chaos, when today's hybrid vehicles batteries end up in landfills. With the development of hybrid cars, the evolvement of alternative batteries for the hybrid industry have re-opened the environmental debate about conventional car battery technology.

According to environmental researchers, there are many types of batteries, where some are very toxic and others are less: lead acid or nickel cadmium batteries have a harmful impact on the  environment. Then, the current batteries used in hybrids today, the nickel metal hydride, have a much lower toxicity level.... read more

How to move the public on climate action?

Many Americans believe climate change is an impending environmental threat that faces us in the next millennium, however, although global warming is considered the biggest threat, most people are not committed to making the choices and lifestyle changes that are required. 

While, global temperatures are rising, weather conditions change across the world, the Arctic ice cap is melting, scientists and environmentalists are presenting urgent warnings about climate change, politicians, business leaders and financial ventures incentivize, stimulate and invest in new Green technologies - people acknowledge the threat, but are still not taking personal actions to reduce the problem.

Today, a number of scientists acknowledge that some climate change may not be reversible.

What is 'green' software design? What is Open Source development?

What does green have to do with software developers and software engineers?

How can the Information Technology (IT) industry improve its green credentials?         

Devising high performance computing, i.e. developing ‘smarter’ software to exploit parallel, multiprocessor architectures will inevitably mean more efficient use of hardware resources and better coding techniques.

Another major aspect of green software is sustainable software development and the use of Open Source methodologies.

Electric vehicles will have an impact on local power grids

The heavy dependency on fossil fuels such as oil, gas and coal, along with the drive to limit greenhouse gases, have presented a global concern in the past few decades. Despite the best efforts of many governments to move toward renewable energy solutions, there are technological and economical considerations that affect the short-term outlook.

With the growing efforts to limit carbon dioxide emissions, the number of electric vehicles (EVs) and plug-in hybrids on our streets, have been increasing steadily.

What would happen to our power grid, when tens of thousands, even millions, of electric cars users begin charging their vehicles every day, throughout the day, at work, at home or office?
