The Future of Energy Efficient Vehicles + (Infographic)

Flying cars were expected to be the future by 2000; despite erroneous expectations, cars have become radically advanced within recent years. Cutting-edge technology has prompted the birth of the car of the future due to anxieties of energy efficiency and rising pollution.

By 2025, all new U.S. vehicles must be equipped with a 55mpg+ fuel range. To contend with new fuel regulations, each year a car must be 5% more fuel-efficient. The price at the pump is expected to increase 25% by 2025; presently, the average vehicle gulps an annual average of $1700. Future hybrid & electric vehicles may cost $2400 more, but consumers will save $8200 in additional expenses.

Plug-in vehicles (PEV) or electric vehicles (EV) are gaining in popularity, but critics cite inflated prices, shortage of fueling stations, and limp technology advancements as probable disappointments. Despite the EV knockers, the Tesla Model S recently earned Car of the year for 2012 by Automobile Magazine and received Motor Trend’s Car of the Year honors in 2013. Cadillac, BMW, Audi, and Honda are soon to follow in the EV trend in 2014.

Alternative fuels are the clean fuels of the future: liquid petroleum gas (LPG), ethanol, biodiesel, and natural gas. LPG and natural gas are undoubtedly promising; these domestic fossil fuels yield less toxic pollutants and greenhouse gases. Biodiesel, unlike its petroleum counterpart, originates from vegetable oils and animal fats. Corn and other domestic crops create ethanol. The government promotes these unorthodox fuels with alluring tax incentives to qualifying consumers.

House Bill 2453 may leave an unpleasant taste in some consumer’s mouths after it is passed. This tax, to be blunt, fines individuals to drive an electric vehicle. This gas tax would be aimed at 2015 or later vehicles, with 55 miles/gallon or more. A little background information: 60% of state projects are funded by taxes on gasoline. Thus, states are collecting less tax money because of existing and future electric and hybrid vehicles. Point blank, the fee would be 1.56 cents per mile.

These destined energy efficient vehicles could conceivably constitute 65% of the market in 2025. Consumer demand, credits, and government incentives will determine the car dealership of the future.

Renewable Energy And The Crusade Towards Innovation

Renewable energy is continually replenished and non-polluting: geothermal, sun, water, and wind. The popularity of renewable energy is growing due to high oil prices, change, government legislation, and mounting government support paired with incentives. Greenhouse gases are detrimental to the Earth’s atmosphere; these gases allow sunlight to enter the atmosphere, thus trapping heat in the atmosphere. These rising temperatures may trigger climate change. Greenhouse gases in North America are primarily from energy consumption due to economic growth

Solar power technologies utilize the sun’s energy to provide electricity. Solar power supplies less than 1% of U.S energy requirements; nevertheless, solar technologies are quickly advancing. Solar technologies used for harnessing solar energy include photovoltaic cells, passive solar designs, and flat-plate collectors. The applications used to adapt solar power into electricity are costly, yet, the substantial potential of solar energy remains.

Hydropower is the most conventional renewable energy source, and uses flowing water to produce electricity. Major dam sites in the United States include the Tennessee Valley, the Colorado River, and the Northwest. Hydropower is suitable for supplying large electricity requirements and is the least expensive renewable energy source.

Wind energy applies wind turbines to generate electricity; this sector of renewable energy is the fastest growing. Ideal placement for turbines is in an area of strong winds: Alaska, the Appalachians, and the western United States.

Geothermal energy utilizes natural sources of heat trapped beneath the Earth. Underground hot water or steam is the conventional form of generating power. Geothermal technologies embrace geothermal heat pumps, direct-use systems, and reservoirs.

Innovative technologies continuously attempt to improve the employment of renewable energy.

Livestock methane gas emission is a severe threat to the global climate. In British Columbia, the Cowpower Program encourages residents to pay a slight percentage on their utility bill. This premium will help pay for an anaerobic digester- bacteria is converted into organic material, creating energy.

Groundbreaking transportation could ease the reliance on fossil fuels for energy. The invention of a speed vacuum train could be reality in the near future. A speed-vac train is based upon the idea of removing the air from a sealed tub, and pressing a train through. Conventional trains use a great deal of energy; the vacuum theory would be matched with magnetic levitation devices, allowing trains to reach 4,000 mph.

The latest in solar technology has spawned the idea of a device to trap light, which progresses the proficiency of organic solar shells by 175%. This “black hole for light” could possibly allow for an economical, marketable solar shell.

Budgeting For Energy Efficiency Projects

Companies always look to make the best decisions when selecting capital projects to work into the budget; simple metrics like Return on Investment and Internal Rate of Return tend to dictate how the budget for these projects is written each year. In an effort to increase the bottom line, investments are often times funneled toward projects and purchases that directly affect sales rather than decreasing operating costs, but sales growth is never guaranteed.
In other cases, capital projects are indefinitely suspended, forcing companies to make due with what they have until either more funding becomes available or sales increase. [Read more…]

The Sacramento Bee reports that California may be missing out on ‘green’ manufacturing jobs. While California is a leader in encouraging renewable energy, almost all green technology products are manufactured outside of the state. As a state facing double-digit unemployment, luring manufacturing back to California could help fuel the state’s economy and offer jobs to the thousands of unemployed workers.

According to The Daily Camera, Boulder is considering commercial energy-efficiency requirements as voluntary incentives have not produced the energy reduction the city hoped to achieve. The program would start with expanding current inventive programs, followed by a mandatory energy rating and reporting. Read more

Smart Grids: Bringing Utility Systems into the 21st Century.

What is a smart grid?
Just as smart phones have evolved into multi-purpose devices that support a wide range of applications, smart grids have become a way to computerize the electric utility grid and better manage the increasing energy needs of 21^st century consumers.

The “grid” encompasses all the networks that carry electricity from the plant where it is generated to the homes and office buildings where we consume it. Smartgrid.gov refers to our current grid as an “aging infrastructure” set up to handle only simple energy demands.

For the past 100 years, utility workers have had to go out to gather much of the data needed to provide electricity — reading meters, looking for broken equipment, measuring voltage, and so on. And most of the devices utilities use to deliver and manage electricity rely on manual or analog systems. Now, the electricity industry is taking great strides to modernize the process.

A smart grid system digitizes data collection and also acts on information about consumer behavior — similar to the way Google learns your online searching habits and Netflix knows your movie preferences. Each device on the network has hi-tech sensors to gather data and automation technology that allows the utility company to adjust and control each individual device or millions of devices from a central location.

In addition, a smart grid system can

Detect faults and isolate outages
Restore electricity quickly and strategically after power disturbances
Reduce management costs for utilities, lowering power costs for consumers
Reduce peak demand, which will also help lower electricity rates
Enable active participation by consumers in demand response
Integrate large-scale renewable energy systems
Integrate customer-owner power generation systems
Operate resiliently against physical and cyber attack

Who supports the smart grid?
In 2007, Congress passes the Energy Independence and Security Act, which supports the DOE in leading and coordinating a national grid system. Such a system would involve upgrading the current system or replacing it altogether. Smartgrid.gov advocates that a modern grid be constructed “from the bottom up to handle the groundswell of digital and computerized equipment and technology dependent on it.”

In 2009, the Obama administration allocated $3.4 billion in grants as part of a stimulus package to help utilities develop and implement technologies such as smart meters, digital transformers, and automated power monitoring and management systems.

We have seen smart grids deployed on a smaller scale in cities like Austin (2003) and Boulder (2008), and several areas in Europe and Canada are currently working towards large-scale smart grid systems.

Smart grids are designed to give consumers more control over their energy use. Imagine monitoring and managing electricity just as you do your bank account. Smart grids will provide a clear and timely picture of how much electricity you use and when it costs the most to run.

The Evolution of Insulation

As we grow more aware of our environmental impact—and as utility bills grow more costly—energy efficiency becomes a central concern in construction projects and building updates. LEED certifications set efficient buildings apart from the rest. Pink attic insulation doesn’t quite cut it anymore.

Natural Insulation
Although it’s a hot topic now, energy efficiency—insulation in particular—is nothing new. Since the beginning of time, the Earth and its inhabitants have found remarkable ways to regulate temperature. Atmospheric gases gather in the ozone layer, water surrounds land, mammals grow fur and store body fat, birds are born with feathers, and early on, humans discovered heat-trapping material like wool.

We have always put extra effort into shielding ourselves from the elements. Early humans built their homes out of natural insulators like grass, leaves, straw, mud, ice, and mountainsides. And landscaping wasn’t always about aesthetics—trees planted near houses provided precious shade and insulation.

While keeping extreme temperatures out, people also came up with ways to generate heat within. Some buildings in the Roman Empire and ancient Korea used empty spaces in floors and walls to conduct air heated by furnaces. By 1700, Russian engineers began developing water-based systems to circulate heat.

Synthetic Insulation
With the advent of modern heating systems came the need for better insulators. After all, gas and electric systems don’t come cheap like heat from a wood-burning furnace, and they create conditions that need to be regulated in order to work properly.

In 1930, Dale Kleist, a researcher at the Owens-Illinois Glass Company, made one of those lucky mistakes that so often leads to a monumental discovery. While trying to seal two plates of glass together, he accidentally shredded the glass into tiny fibers with a high-pressure air hose. Thus, fiberglass was born and soon found its most common form in blanket insulation.

Meanwhile, manufacturers began to realize the benefit of insulating not just their buildings but their heat sources as well. This helped protect workers and equipment, save energy, and improve overall efficiency.

Custom Insulation
We’ve come a long way since adobe huts and igloos. Today, engineers use R-values (the measure of thermal resistance) to quantify and compare the insulating capability of different materials. In this way, they can combine the most effective insulators and create premium insulation.

Opportunities for Greater Efficiency in Custom Molding

As more and more manufacturers see significant energy savings after insulating their machines, insulation jackets are becoming priority number one in many energy management strategies.

UniTherm has been supplying insulation jackets in the plastics industry for over 30 years, and with each new product and custom service, UniTherm strives to address a specific processing need. With this innovative mentality, UniTherm can provide opportunities for greater efficiency, as it has with its new product called QuickCool.

QuickCool is an insulation jacket with an additional feature—it is designed to open easily so that machines can quickly cool as they are prepared for different processes. QuickCool wraps completely around the barrel and insulates as well as UniTherm’s other jackets, but it has high-temperature straps on the inside to hold it in place while the top flap opens to release heat when necessary. Otherwise, the top flap velcros tightly to the rest of the jacket to keep machines working at high efficiency with minimal heat loss. This way, barrels and heater bands are always easily accessible without having to remove the entire jacket, and machines can reach and maintain different desired temperatures as needed.

QuickCool closed to insulate

QuickCool open to release heat

Barbara Arnold-Feret, custom molding expert and new addition to UniTherm’s sales team, calls QuickCool a “flexibility enhancer.” QuickCool, she explains, “offers all the advantages of insulation along with the ability to change temperatures quickly. It allows great flexibility for molders looking to cool their machines for whatever reason, including material changes.” No longer do custom molders need to worry about insulation encumbering their access to the machines or their ability to switch processes involving different materials. “It is especially convenient when working with polyolefins and perfect for molders that make a little of everything,” says Barbara.

In fact, a custom molder with 3,000 molds running short runs with PolyPro and ABS installed QuickCool blankets on its machines and found that the product allowed them to cool from 550˚F to 350˚F in the time it took to change the mold.

UniTherm has been supplying insulation for over 30 years, and the Research and Development team continues to explore new energy-efficient solutions. They are excited to offer a product that will not only save energy but also adapt to the alternating processes in custom molding.
