The natural evolution of energy, Part I - www.micronesiarenewableenergy.com

THROUGHOUT history, energy consumption patterns have changed significantly from a non-complex task like burning wood for heat to the enormous power created from nuclear energy. People have found new ways to develop energy sources and use them to their advantages, as they were determined to find the most efficient and economical ways to make their lives easier, safer and cost-effective. Energy will always be a conscientious effort with the increasing emphasis on sustainability and energy independence.

So how did we go from burning wood for heat and light, to drilling for oil, to the development of renewable energy sources?

Let’s take a step back in time.

Around 1 million B.C., man was able to control fire by burning wood, straw, and even dung to cook, stay warm, and to protect themselves from animals. The Chinese refined crude oil to burn in lamps and heat their homes as far back as 2000 B.C. And in 1200 B.C., the Polynesians used the wind to sail the ocean while the Persians built the first windmills in 600 B.C. Water was used to turn large wheels to make energy for small machines in 200 A.D. Europe.

As the 1700s approached, humans began to enjoy the advantages of using fire. Wood, served as the predominate form of energy. Water wheels were built in streams and rivers to capture energy as a power source, along with wood combustion for heating and cooking. In 1752, Benjamin Franklin took that famous kite into the storm to study electricity from lightening.

Large amounts of coal were discovered in North America. This form of energy began to replace other energy sources, such as water and wind, and became the main source of energy around the world. The 1800s brought about the Industrial Revolution which started our need for more energy to run many new machines. During the earlier years of the Industrial Revolution, steam-powered machines used in the manufacturing industry began to replace wood as the dominant source of energy. As more energy was needed, so was the need for coal.

By the 1950s, other efficient sources of energy began to supplement coal. Oil and natural gas were easier to handle and to transport and was a cleaner source of energy. Soon natural gas and oil became the dominant source of energy surpassing the century-old coal dominance. The demand for natural gas and oil continued until the mid-1970s when economic downturns and price manipulation contributed to the shortage of oil and natural gas causing spikes in fuel prices. These spikes still exist in today’s market. The 1970s also brought about a decrease in the production of U.S. oil and an increase in dependence of imported oil.

In the 1970s, the popularity of nuclear energy was growing until disasters like the Three Mile Island and Chernobyl. Safety concerns of meltdowns and proper disposal of nuclear radioactive waste slowed nuclear energy’s progress.

In the 1990s, concerns for climate change began. Due to pollution and the restricted availability of fossil fuel, thoughts started to shift back towards natural energy or as we call it today renewable energy. Today, solar power has grown 55 percent thanks to the lower costs of solar panel prices. Geothermal energy accounts for 27 percent of the nation’s energy supply and wind accounts for .75 percent. The largest portion of renewable energy still comes from biomass and hydroelectric resources.

When is the right time to purchase a solar energy system? (Part II) - www.micronesiarenewableenergy.com

LET’S face it. Prices for fossil fuel are never going to decrease to what they were in 80s or even the early 2000s.
Time is working against us. Installing a solar energy system is more affordable than it’s ever been. When you choose to install solar power, you’re not only making a good choice for the environment, but you’re going to save money on your electric bill.

Last week we discussed several reasons to install an energy system today versus tomorrow, and here are a few more reasons:
  • Why put off what you can do today? Save cash on your electricity immediately. Think about how much you pay monthly for electricity. Would you like to cut you power bill in half or maybe even eliminate it altogether? Although there is an initial cash outlay up front, you will begin receiving a return on your investment as quickly as the system is turned on.
  • Be among the first to beat the increasing electricity prices. The need to upgrade or replace the existing aging infrastructure, the rise in fuel costs, and implementation of new technology all have a cost associated with it which will be passed onto us, the consumer. Buying a system today to meet 100 percent of your electricity needs hypothetically will put more money back in your pocket as prices increase annually.
  • Increase the value of your home. The demand for greener homes in real estate market is increasing; most homebuyers will pay more for energy-efficient features. Even if you are not looking to sell in the near future, solar systems have longevity. You can reap the benefits from the system now while giving it the selling edge in the future.
  • Helps the economy. Purchasing a system today creates local green jobs, supports local renewable energy companies, and providers.
  • The environment needs our help now. With talks of the effects of climate change and its potential danger, if you install a solar system now, you can do your part and substantially reduce your carbon footprint for a cleaner future for you and your children.
If these reasons do not convince you consider this: A typical 8KW solar energy installation avoids 209 tons of carbon dioxide emissions in one year. This installation is equal to planting 63 acres of trees, removing 40 cars off the road, and not driving 505,000 miles annually. Every kilowatt-hour of clean energy produced is one less kilowatt-hour of energy that needs to be generated through coal fired generation

Be the leader in your community. Start the trend and install a solar or renewable energy source today. You will be one of the first to start a clean energy revolution and save money.

Guam Renewable Energy Association to be acknowledged - www.micronesiarenewableenergy.com

By THOMAS JOHNSON - JOURNAL STAFF

On Sept. 24, Gov. Edward B. Calvo will convene with members of Guam's
alternative energy community at the Guam Energy Office to acknowledge and
approve the Guam Renewable Energy Association as an entity for positive
change on the island.

Eulogio S. "Shawn" Gumataotao, an associate member of GREA, said the
association is composed of local business owners and professionals whose
primary businesses lie within the fields of renewable energy and energy
efficiency. "It was a way to help spread the voice of the industry, as well
as giving the island a big push to begin this effort to go away from fossil
fuels and move toward more renewable sources of energy."

The organization, which is presided over by Micronesian Renewable Energy
Inc. vice president Jeffrey Voacolo, has been meeting unofficially for four
to five months, according to Gumataotao, but only in early August
established itself as an official entity. "It's fully incorporated, and
we've established a board of directors, made up of our private sector
leaders in this industry," Gumataotao said. Voacolo could not be reached
for comment, as he was off-island overseeing an MREI project in Pohnpei.

Alfred K. Lam, president and CEO of Green Energy Solutions Inc. and
vice-president of GREA, said that the group currently boasts about 26
members from various private and public entities, including William Hagen,
director of Pacific Solar & Photovoltaics Inc., and is working alongside
the Guam Energy Office and the Consolidated Commission on Utilities to move
the renewable energy industry forward.

In addition to providing the renewable energy industry with a voice,
Gumataotao and Lam agreed that the primary purpose of the organization is
to police the industry and set standards to ensure that all installations
are done right and performed in accordance to proper safety and business
procedures, as well as the rules and regulations established by the Guam
Power Authority.

When is the right time to purchase a solar energy system? - www.micronesiarenewableenergy.com

MANY of us want to do our part to help keep our environment clean. Saving money while helping makes it more attractive. That brings up the question of when should you make the switch from fossil fuels to solar energy – now or later?

I was often asked that question followed by “Why should I buy a system now? In another year it will probably be cheaper and the technology will be more efficient.” I respond using an example of a cell phone. If you need a cell phone, buy one now and do not wait till next year when the prices may increase. There are many reasons why now is better than later.

Tax credits, rebates and incentives

Within the next few years, the federal and local governments will start to cut, change and reduce rebates on tax credits and incentives. As the national debt rises, the federal and local governments are going to find ways to save money. By cutting many of the tax credits and incentives, these governments would save millions. Take advantage of these benefits now while they are still available. Timing is everything. Understanding the ins and outs of these breaks in your area will help guide your decision.

Cost of solar technology

The cost of solar panel systems has declined over the years and now is at a plateau. As a matter of fact, they are the lowest they have been in years. The lower costs of the systems make it a more attractive solution to saving money. Since solar energy is becoming more popular, there has been a rise in the number of manufactures of the solar power systems and their components. There is a surplus in supply and the demand is starting to catch up. Based on the simple law of supply and demand, the greater the supply, the lower the cost. Once the demand catches up, prices will most likely start to rise again. This upswing in prices may happen sooner than we think – especially as the cost of fossil fuels climb. There are many reasons that the demand for solar energy can rise.

Depletion of raw materials

For hundreds of years, humans have turned to Mother Earth to supply raw materials that are needed to produce the power we require to run modern day society. As the world’s population grows, so does the demand for power. The Earth has a finite amount of raw material that can be converted into power. Sooner or later, we will deplete these materials and society will have to look elsewhere. I’m not saying the Earth will run out of materials tomorrow, but there will come a time that the companies that supply the natural materials will start conserving what they harvest and place an exuberant price on what they do sell. This will cause a steep rise in power prices that will raise the demand for alternative power sources.

Political instability

The United States looks elsewhere to acquire most of its fuel. Many of the nations that supply our nation are countries that are not politically stable. It can happen overnight that one of these nations will decide not to sell to the United States and the price of fossil fuels will skyrocket.

Hiring the right renewable energy company (Part II) - www.micronesiarenewableenergy.com

LAST week’s article covered a few questions to ask when choosing a contractor to install a renewable energy system. Finding a contractor who is knowledgeable and trustworthy is imperative. Not only should you ask questions about your contractor but what your contractor will be offering. Educating yourself will avoid any unwanted experiences. Be sure your contractor takes the time to educate you on your new system.

Know your contract

Read the proposed contract and make sure it reflects what the contractor will do and will not do. The contract should state when the contractor will start, how long it will take for completion, and if the contractor performs a structural analysis. An analysis is pretty basic and does not cost a lot; most solar panels are well under the maximum allowable load for most roofs.

Do you need a building permit? 

The answer is yes. “Yes” will protect you from an inadequate installation. An electrical permit and a structural review are necessary. You will also require a Guam Power Authority interconnection permit. Your contractor should be able to have these drawn up and get the necessary permits for you.

Installation

If solar panels are mounted on your roof, ask how the panel’s supports will be mounted and caulked to prevent leaks. The holes should not be drilled into the roof while the roof is wet. Check your ceiling after installation to verify the panels are bolted into load bearing structures such as the rafters, purlins, or trusses and not bolted into decorative sheathing. Verify the location of the inverters, the mechanism that converts the solar energy to usable power. The inverters should have adequate shade and good air flow to keep the inverter cool. If the inverter is mounted outside on a south-facing wall, a shade structure should be placed over it to reduce the high temperatures from direct sunlight, this will affect the life expectancy and efficiency of the inverter.

Ask for a shading analysis for your solar energy system. Too many times I have seen installations being placed where trees, walls or other buildings block the sun’s light. A qualified solar installer will have a shading analysis tool and give you the reports as part of the proposal.

Maintenance

Verify who will do the maintenance on the system; this should be spelled out in the contract. Typically, the panels should be cleaned at least twice a year.

Warranty

Most solar panels are usually warranted for 25 years or more and the inverters are typically warranted for 10 years. If your contractor offers an extended warranty on the inverts I highly recommend purchasing it; it will be well worth the money. Understand your warranty details and how to apply for a repair or replacement on all equipment. This should also be spelled out in the contract.

Know how much you are saving

Ask what percentage of your total power will your new installation will provide annually; the design of the system is just as important as the installation. ?To get an estimate review your last 12 months of consumption in and compare it to what the solar system will produce. Your contractor should be able to help you with this. If you do your research online, keep in mind that Guam is different than say Arizona or Hawaii due to the amount of sunlight we receive. A monitoring system can be added to monitor your system’s efficiency and output. For a residential system, a basic monitoring system will be able to verify what your system is producing. In a Power Purchasing Agreement, or a larger system, a more detailed revenue grade monitoring system will need to be installed.

Knowing your contractor, his/her past performance and understanding your contract are essential to a hassle free installation and an effective renewable energy system. Take your time and do your research in the end you will be very happy with the money saved and your new greener living.
