2014 Green Lifestyle Resolutions

First come the New Year, and then comes the resolutions.  With eco awareness on the rise, it’s not surprising that many New Year’s resolutions are to live a cleaner and more sustainable life. While green living may be the new buzz word, to start doing it may take some definition and direction. Here are a few ideas that may help you move toward a more green 2014:

1.  Practice the 3 R’s: Reduce, Reuse, and Recycle. new-year-resolution
2.  Buy organics:  Shop your local farmer’s market for organic fruits and veggies and look for natural personal care and clothing made from natural fibers.
3.  Bring your own reusable bags when you go shopping.
4.  Composting as much as possible. Collect your table scraps and lawn clippings in a yard composter to make free fertilizer! Use it on your plants, gardens, tree pits, anywhere!
5.  Recycling: recycle everything! Paper, materials, home items, and more!
6.  Energy efficiency: purchase energy star certified appliances.  Buy and use renewable or wind energy and monitor your use of energy.
7.  Water: Reduce you water usage with xeriscaping and using sprinkler systems in the yard. Use shower timers and other water conservation tools to reduce your daily water usage.
8.  Indoor air quality: use chemical free cleaners, live plants, sustainable fabrics and paint in your home. Your indoor air quality will improve and you’ll support sustainable businesses producing green products.
9.  Wash your clothes in cold water. You will reduce your energy consumption by reducing the amount of heated water needs. Also, instead of using the dryer, try to hang your clothes outside or indoors on a folding rack .
10.  Play outside. Have fun and keep fit by appreciating all that nature has to offer: parks, trails, gardens, etc.
11.  Green your travel. Try a eco trip this year for your vacation.
12.  Get an Energy Audit: Find an energy audit company in your area to analyze the energy efficiency of your home.  An audit can potentially save you thousands of dollars by making a few changes.

Have a Happy (Green) New Year!!!

Why Teach Fuel Cells?

Renewable technology now plays an important role in the modern science classroom, introducing children to the astonishing potential of alternative sources of energy. However, while most children have heard of solar panels or wind turbines, fuel cell technology still remains a mystery to many. Yet this is a crucial time, with the mass production of hybrid fuel cell vehicles, the construction of hydrogen refueling infrastructure in the EU and America and international telecom companies increasingly turning to fuel cells for their energy needs. Fuel cells have an enormous amount to teach, both in terms of key scientific principals and their relevance to the greentech innovations happening all around us.

Hydrogen fuel cells

Fuel cells are bursting with fascinating science! The key process of a hydrogen fuel cell is the conversion of hydrogen atoms into electrical energy by separating the nucleus from the electron. The electrons are then diverted around an electric circuit while the positively charged hydrogen ions travel through the proton exchange membrane. Then there’s the generation of hydrogen itself—the separation of hydrogen from oxygen through water electrolysis, the hydrogen molecules with a slight positive charge travelling to the cathode while the slightly negatively charge oxygen is attracted to the anode. Molecular bonding, valancy, ions, electrolytes and so much more, just from one alternative technology.

Other types of cell

While hydrogen dominates the headlines at the moment, other fuel cells have enormous educational potential. Direct ethanol fuel cells are in many ways the most efficient power generators of the Horizon education range. The process lasts for hours, does not require combustion, and is completely silent. Saltwater fuel cells operate a little differently, generating electricity through a saltwater electrolyte with magnesium plates around the anode.  Thermal cells convert the temperature difference between hot and cold water into electrical energy. One of the key lessons of these alternative fuel cells is just how vast and varied the science is—and how many options we would have if we truly embraced a fuel cell economy.

Sustainability

With most of our education kits we try to integrate more varieties of alternative technology to enable students to build self-sustaining renewable energy systems. Wind turbines or photo voltaic panels power the electrolyzer to separate out hydrogen from water. The fuel cell converts hydrogen to electrical energy which then powers a propeller or LED— a great way to demonstrate the principles of energy conservation and conversion. Also, students also get to study things like the effect of shade on solar panels, wind resistance, the optimum number of blades for effective wind energy generation and many other tests and experiments.

Universal Ideas

The addition of fuel cell and renewable technology to the science curriculum doesn’t mean that the basics principles of physics and chemistry are somehow overlooked. In fact our fuel cell education sets reveal the workings of water electrolysis, the electrical circuit, resistance, voltage, current, RPM and everything else a conventional lithium battery electrochemistry svet can supply. Plus, extra features such as the Renewable Energy Monitor allow teachers and students to not only measure energy, but also take this data and view it graphically in real time on a computer screen.

Fuel cells are the future of emergency backup power, transportation, aerospace, telecommunication support and so much more. With a carbon-neutral world fast approaching, it’s time we introduced students to this crucial technology and started inspiring the next generation of scientists to push the boundaries of renewable science.

Benefits of Residential Solar Panels

The Benefits of Residential Solar Panels

The environmental impact of installing solar panels are evident. The installation of residential solar panels will reduce the size of your carbon footprint and your share of greenhouse gases that are produced annually. As you go through the decision-making process of determining the feasibility of installing residential solar panels, here are a few key points to consider:
  • Start-up Costs - You can reduce the substantial initial outlay by taking advantage of incentives and tax rebates.
  • Self sufficiency and independence -The ability to get of the grid can be liberating. You can also remove a bit of market volatility that can be caused by terrorism, natural disasters and market forces.
  • Return on Investment – The initial purchase of solar panels is obviously a substantial investment, but energy genera
  • solar panelstion starts immediately, resulting in immediate savings on electrical costs. After the initial outlay is covered, in 10 – 15 years, the system will provide pure profit.
  • Remote Installation – Cabins, sailboats, RV’s, these are great places to see the advantages of solar energy. Solar power is often much more cost effective to establish in remote areas than conventional power infrastructure.
  • Environmental Impact – The use of solar energy produces no emissions or noise pollution.
  • Home equity – Passive solar layout & landscaping concepts increase the value of a home.
  • System Longevity – Solar panels have the capability of collecting energy for 40 plus years and manufacturers typically warranty the systems for 20 to 25 years.

Eco-tips for the Office

Five eco-tips for the workplace:

Here are five tips to help make your work environment greener:

Reduce and reuse paper:

  • print and copy double-sided
  • Print drafts on unused reverse sides of paper
  • e-mail your documents as attachments
  • edit documents on screen rather than printing out and hand editing

Reuse boxes:

If you receive a box that is still in good condition, instead of discarding of the box, save it for a future outbound shipment. Simply remove previous shipping labels  and mark-out or cover any previous markings and you extended the life of the box.

Ditch the plastic styrofoam cups:

Get rid of the disposable throw-away cups- the one’s you use for coffee and water fill-ups. The one-use cups accounts for a great deal of office waste.  Simply bring your own cup and provide additional washable cups for visitors.

Switch Off:

The amount of energy wasted in the workplace accounts for over 15% of total energy usage. Items such as computers left on unattended, especially in the overnight hours. Cut your energy use by switching off your computers, copiers, printers and lights when not in use. Also, reduce your phantom energy loss be using smart power strips and/or unplugging unused devices. Remember lower energy bills also mean a better bottom line.

Turn down the heat this winter:

Your heating costs will go up by 8% each time you increase the temperature by just one degree. A 2°C increase in office temperature creates enough CO2 in a year to fill a hot air balloon. Lower the thermostat and your energy bills at the same time.
