Nick Slawicz investigates tomorrow’s cars before taking a close up look at today’s electric vehicles.
In 2006, Chris Paine’s documentary Who Killed the Electric Car? was released to lukewarm (but still generally favourable) critical consensus. A common complaint, however, centres on its polemical view that the auto industry’s future lies in the battery electric car (BEV), implying a lack of alternatives as serious contenders for the title of Car of Tomorrow.
But this is not the case, and research is ongoing into dozens of fuel sources, ranging from the well known (liquid petroleum gas, hydrogen, biofuels made from renewable plant material) to the less publicised (liquid nitrogen, compressed air). There are also the outright ridiculous: despite its breaking two out of the three laws of thermodynamics, claims of a car fuelled entirely by water have been running wild since at least 1935. Though several websites offer engineering schematics and testimonials as to its success, there is no proof that it works under laboratory conditions.
Assuming for a moment that Big Oil is not attempting to smother the threat of water-fuelled vehicles, it seems likely that whichever fuel source powers the car of the future is going to have some serious drawbacks. Fossil fuels release harmful gases into the atmosphere. Biofuels generally have a lower efficiency than fossil fuels, and may produce harmful by-products at the point of production. Hydrogen fuel cells emit water only at the user’s end, and still require a lot of energy – and thus harmful waste – to manufacture; they are also subject to “leaching”’, which is when (like a helium balloon) the fuel seeps through the container itself and is lost without being used. BEVs work well, but currently have a limited range and are significantly more expensive than internal combustion engines.
It seems as though a compromise is needed for now. And, with the infrastructure already in place for gasoline-powered vehicles, an economic downturn and a waiting period of years before a single suitable alternative could be implemented (let alone supported for multiple vehicular energy sources), that compromise may well be the hybrid electric, which has already been snapped up by millions of people around the globe. Sales of the Toyota Prius alone reached 38,600 in the UK between 1997 and 2010, and show no signs of slowing down. Yet, improvements to all alternative fuel sources will come about with funding and effort from industry. When the clear successor to petrol power emerges, as it must, billions of pounds will be up for grabs – and the environmental benefits will be felt by all future generations.
The electric car might be a promising option in the future of alternative fuel vehicles, but it is not without its flaws. In the recently-released RAC Report on Motoring for 2010 32 percent of respondents stated they would “definitely consider buying an environmentally friendly car”, with an additional 56 percent claiming they “might” consider this as an option. However, fewer than half of those polled stated that an electric car would be a consideration.
And why is this the case? Worries about the practicality of electric cars are many and varied, including the top speed and the distance they can be driven between charges, both of which, in the past, have been limiting factors in the development of battery electric vehicles (BEVs).
Thankfully, we’re now past the stage of the concept car, and new production cars are emerging that are designed to fix the perceived problems and test the boundaries of what BEVs can do. The most famous of these is probably the Tesla Roadster – developed two years ago in America and currently available for approximately £87,000. It offers an impressive range and speed: a travelling distance of 245 miles per charge and 0–60 mph in 3.7 seconds.
More recent developments in BEV technology have resulted in the production of the Nissan Leaf, the latest darling of the environmental movement. Although its top speed and average miles per charge are low compared to the Tesla Roadster (0–60 mph in 7 seconds and between 73 and 100 miles per charge, depending on which source you go to), so is the price tag: at £23,990 (including the new 20 percent VAT rate), the Leaf is proof that affordable electric cars are a practical solution, even if they are not yet as widespread as they could be. In fact, the car industry seems so confident its future lies in this direction it has already awarded the Nissan Leaf 2011 European Car of the Year.
As the question of BEV technology’s future success is still up in the air, we environmentally concerned can remain confident that it is being given every opportunity to flourish in the automobile marketplace.
How Going Green Can Save A Company Money
What is going green?
Going green means to live life in a way that is environmentally friendly for an entire population. It is the conservation of energy, water, and air. Going green means using products and resources that will not contaminate or pollute the air. It means being educated and well informed about the surroundings, and how to best protect them. It means recycling products that may not be biodegradable. Companies, as well as people, that adhere to going green can help to ensure a safer life for humanity.
The first step in going green
There are actually no step by step instructions for going green. The only requirement needed is making the decision to become environmentally conscious. It takes a caring attitude, and a willingness to make the change. It has been found that companies have improved their profit margins by going green. They have saved money on many of the frivolous things they they thought were a necessity. Besides saving money, companies are operating more efficiently than before going green. Companies have become aware of their ecological responsibility by pursuing the knowledge needed to make decisions that would change lifestyles and help sustain the earth’s natural resources for present and future generations.
Making needed changes within the company
After making the decision to go green, there are several things that can be changed in the workplace. A good place to start would be conserving energy used by electrical appliances. First, turning off the computer will save over the long run. Just letting it sleep still uses energy overnight. Turn off all other appliances like coffee maker, or anything that plugs in. Pull the socket from the outlet to stop unnecessary energy loss. Appliances continue to use electricity although they are switched off, and not unplugged. Get in the habit of turning off the lights whenever you leave a room. Change to fluorescent light bulbs, and lighting throughout the building. Have any leaks sealed on the premises to avoid the escape of heat or air.
Reducing the common paper waste
Modern technologies and state of the art equipment, and tools have almost eliminated the use of paper in the office. Instead of sending out newsletters, brochures, written memos and reminders, you can now do all of these and more by technology while saving on the use of paper. Send out digital documents and emails to communicate with staff and other employees. By using this virtual bookkeeping technique, you will save a bundle on paper. When it is necessary to use paper for printing purposes or other services, choose the already recycled paper. It is smartly labeled and easy to find in any office supply store. It is called the Post Consumer Waste paper, or PCW paper. This will show that your company is dedicated to the preservation of natural resources. By using PCW paper, everyone helps to save the trees which provides and emits many important nutrients into the atmosphere.
Make money by spreading the word
Companies realize that consumers like to buy, or invest in whatever the latest trend may be. They also cater to companies that are doing great things for the quality of life of all people. People want to know that the companies that they cater to are doing their part for the environment and ecology. By going green, you can tell consumers of your experiences with helping them and communities be eco-friendly. This is a sound public relations technique to bring revenue to your brand. Boost the impact that your company makes on the environment. Go green, save and make money while essentially preserving what is normally taken for granted. The benefits of having a green company are enormous for consumers as well as the companies that engage in the process.
5 Easy Things You Can Do to Make Your Home More Sustainable
Increasing your home’s energy efficiency is one of the smartest moves you can make as a homeowner. It will lower your bills, increase the resale value of your property, and help minimize our planet’s fast-approaching climate crisis. While major home retrofits can seem daunting, there are plenty of quick and cost-effective ways to start reducing your carbon footprint today. Here are five easy projects to make your home more sustainable.
1. Weather stripping
If you’re looking to make your home more energy efficient, an energy audit is a highly recommended first step. This will reveal where your home is lacking in regards to sustainability suggests the best plan of attack.
Some form of weather stripping is nearly always advised because it is so easy and inexpensive yet can yield such transformative results. The audit will provide information about air leaks which you can couple with your own knowledge of your home’s ventilation needs to develop a strategic plan.
Make sure you choose the appropriate type of weather stripping for each location in your home. Areas that receive a lot of wear and tear, like popular doorways, are best served by slightly more expensive vinyl or metal options. Immobile cracks or infrequently opened windows can be treated with inexpensive foams or caulking. Depending on the age and quality of your home, the resulting energy savings can be as much as 20 percent.
2. Programmable thermostats
Programmable thermostats have tremendous potential to save money and minimize unnecessary energy usage. About 45 percent of a home’s energy is earmarked for heating and cooling needs with a large fraction of that wasted on unoccupied spaces. Programmable thermostats can automatically lower the heat overnight or shut off the air conditioning when you go to work.
Every degree Fahrenheit you lower the thermostat equates to 1 percent less energy use, which amounts to considerable savings over the course of a year. When used correctly, programmable thermostats reduce heating and cooling bills by 10 to 30 percent. Of course, the same result can be achieved by manually adjusting your thermostats to coincide with your activities, just make sure you remember to do it!
3. Low-flow water hardware
With the current focus on carbon emissions and climate change, we typically equate environmental stability to lower energy use, but fresh water shortage is an equal threat. Installing low-flow hardware for toilets and showers, particularly in drought prone areas, is an inexpensive and easy way to cut water consumption by 50 percent and save as much as $145 per year.
Older toilets use up to 6 gallons of water per flush, the equivalent of an astounding 20.1 gallons per person each day. This makes them the biggest consumer of indoor water. New low-flow toilets are standardized at 1.6 gallons per flush and can save more than 20,000 gallons a year in a 4-member household.
Similarly, low-flow shower heads can decrease water consumption by 40 percent or more while also lowering water heating bills and reducing CO2 emissions. Unlike early versions, new low-flow models are equipped with excellent pressure technology so your shower will be no less satisfying.
4. Energy efficient light bulbs
An average household dedicates about 5 percent of its energy use to lighting, but this value is dropping thanks to new lighting technology. Incandescent bulbs are quickly becoming a thing of the past. These inefficient light sources give off 90 percent of their energy as heat which is not only impractical from a lighting standpoint, but also raises energy bills even further during hot weather.
New LED and compact fluorescent options are far more efficient and longer lasting. Though the upfront costs are higher, the long term environmental and financial benefits are well worth it. Energy efficient light bulbs use as much as 80 percent less energy than traditional incandescent and last 3 to 25 times longer producing savings of about $6 per year per bulb.
5. Installing solar panels
Adding solar panels may not be the easiest, or least expensive, sustainability upgrade for your home, but it will certainly have the greatest impact on both your energy bills and your environmental footprint. Installing solar panels can run about $15,000 – $20,000 upfront, though a number of government incentives are bringing these numbers down. Alternatively, panels can also be leased for a much lower initial investment.
Once operational, a solar system saves about $600 per year over the course of its 25 to 30-year lifespan, and this figure will grow as energy prices rise. Solar installations require little to no maintenance and increase the value of your home.
From an environmental standpoint, the average five-kilowatt residential system can reduce household CO2 emissions by 15,000 pounds every year. Using your solar system to power an electric vehicle is the ultimate sustainable solution serving to reduce total CO2 emissions by as much as 70%!
These days, being environmentally responsible is the hallmark of a good global citizen and it need not require major sacrifices in regards to your lifestyle or your wallet. In fact, increasing your home’s sustainability is apt to make your residence more livable and save you money in the long run. The five projects listed here are just a few of the easy ways to reduce both your environmental footprint and your energy bills. So, give one or more of them a try; with a small budget and a little know-how, there is no reason you can’t start today.
