The benefits of hybrid commuter vehicles: electric bikes and tricycles

Electric bikes and tricycles have become environmentally responsible hybrid commuter vehicles with excellent mileage and very low operating costs - 3 miles per penny!


Both ebikes and tricycles might transform urban mobility, as more and more people take to them. As a replacement for short car rides, they emit minimal carbon dioxide, compared to a car ride, and help residents reduce their total carbon footprint. Image from Schwinn.com


In addition to environmental benefits, ebike lovers indicate 5 more reasons to prefer electric bike or trike:

1) Health benefits – Electric bikes enable people with temporary or long-term physical limitations to enjoy biking. Many ebike models offer simultaneous motor and pedal use for some degree of physical activity.2) Convenience – It’s always there for you and enables easy riding around town, running errands, and even shopping (it can fit a small load of grocery bags). Parking is never an issue. Some models fit child-seats or a trailer. For longer trips, most models are light and easily fit into an average car trunk.3) Money consideration - Cheaper than a car and you don’t need to pay for car insurance, taxes, and maintenance costs, even parking tickets. There are also considerations of rising gasoline prices.... read more

Smart-Grid solutions and sustainable software

A Smart-Grid is defined as an interconnected network for delivering electricity from suppliers to consumers. It can be referred to at a city level, county, state, or national level, or even throughout a continent. The grid supports electricity generation, electric power transmission and distribution.


Other terms for Smart-Grid are smart electric grid, power grid, intelligent grid, FutureGrid, microgrid, intergrid and intragrid.Original photo from FreeFoto.comOriginal photo from FreeFoto.com


Smart grids use digital technology to save energy, reduce cost and increase reliability and transparency. Software is a critical component to successful Smart-Grid operations. Software standards, security and Open Source/Open Access methodologies have been gaining traction as the solution to Smart-Grid software applications: they are sustainable, cost effective and collaborative.


The Open Source initiative and Free Software methodology are two movements that focus on everyone’s right to use software.


products freely without paying the high costs required by the software companies. They also focus on the principle that the software source code must be available to everyone to modify, enhance, distribute or port to new environments.


Open Source is an architecturally driven approach that is not linked to a particular software company and can be applied at the strategic and enterprise levels as well as in tactical projects.


Using open source software enables the concept of FISDev, a Framework for Integrated Sustainable Development, which helps organizations move towards a software development approach focused on Sustainable Development.

Electric Vehicles also mean bikes and tricycles

Tricycles for adults? Electric bikes as a replacement for cars?

Two and three wheel electric powered bikes, also referred to as ebikes, motorized bicycle or light electric vehicle (LEV), have been gaining popularity. The market for ebikes is growing faster than the one for cars and trucks and it's one of the booming Green sectors.

Motorized bicycles are powered by an electric motor (in the past, some used a small internal combustion engine) and they are distinguished from electric motorcycles and scooters by being capable of being powered by pedals alone, if required.

Electric bikes and tricycles have the potential to revolutionize transportation in our neighborhoods, places of work, and ‘going’ around town. A significant percentage of car rides are for short trips to local destinations, running errands, accessing your town’s shops or business districts, getting to medical appointments, riding to work, etc., often with only one person in the car.

Touted as a substitute to automobiles, electric bikes and trikes enable us to drive a car significantly less. In some cases it may replace a car altogether.

As a transportation mode, ebikes have a direct impact on greenhouse gas emissions (GHG). Automobiles contribute to air, water, and noise pollution. The motored bike’s footprint is so minor when compared to that of a midsize car, which creates thousands of pounds of carbon dioxide emissions in its manufacturing process and, according to the Environmental Protection Agency (EPA), an additional 20 pounds per gallon is burned while driving.... read more
