Commercial Solar Market is a Big Topic for President Obama and other World Leaders at COP21 United Nations Climate Change Conference in Paris

Leaders from around the world have gathered in Paris for the 2015 United Nations Climate Change Conference (COP 21), with the goal of negotiating a binding, universal agreement on measures to reduce human-caused climate change.

These world leaders will try to build consensus on measures to bring Earth’s temperatures down to 3.6 degrees above pre-industrial levels. Though it won’t be easy, the assembled business leaders, policymakers and heads of state believe it’s critical to the survival of the planet that these actions be embraced by every country. While we can’t predict what the outcome of these negotiations will be, it’s clear the United States must lead on this issue—and that’s where you can act for your business, no matter what happens at COP 21.

Untapped Market

According to expert estimates, the U.S. has approximately 50 billion square feet of commercial rooftop space, about 25 percent of which is suitable for solar installations. If you assume a production capacity of around 10 watts per square foot, those commercial rooftops could produce nearly 125 GW of clean power—nearly seven times what’s currently installed in the entire U.S.

A commercial rooftop is defined as a rooftop that’s not on a residence; in other words, the definition covers markets that you wouldn’t traditionally think of as commercial. For example, solar serves retailers, farmers, hospitality, businesses, office complexes, hospitals, warehouses, government and schools—and that’s not even a complete list.

Leading national consumers of commercial solar like Apple, Google, IKEA and Walmart have already realized that solar installations reduce utility bills and cut carbon emissions, and they’ve invested heavily in putting solar arrays on buildings throughout their operations.

So how much can your business make a difference in terms of carbon reductions if you install solar panels? That answer depends on many factors, but let’s be clear: Every reduction in carbon-based energy counts for our planet. For the sake of simplicity, here are three scenarios for three solar installations:

  • If you install a 1 MW solar array on the roof of your Southern California business, each year you’ll reduce carbon emissions that are the equivalent of 100,000 gallons of gas consumed or 963,000 pounds of coal burned.
  • A 750 kW system each year eliminates carbon emissions equivalent to 75,000 gallons of gas consumed or 722,000 pounds of coal burned.
  • A 500 kW system each year eliminates carbon emissions equivalent to 50,000 gallons of gas consumed or 481,000 pounds of coal burned.

(Calculations based on equivalence data from the Environmental Protection Agency)

Financial Savings

Putting a solar system on your business isn’t only about protecting the environment. After all, installing a solar system is a business investment and, like any other investment, you should expect a return. A solar installation could help you reduce your utility bills: the exact amount that you’ll be able to save will depend on a number of factors, including which utility serves you, its electricity rates and your business’ energy consumption. In addition, a commercial solar installation would serve as a powerful demonstration of your company’s commitment to sustainability and climate change.

The Bottom Line

As world leaders find common ground to break the international impasse on bringing human-induced climate change under control, let them know how serious you are about climate change by making a difference in your own company and local communities. Installing a solar array is a good first step to providing future generations with a livable planet.

Sustainable Development; Renewable Energy, Green Building, Water Conservation, Advanced Energy Storage…What’s all this mean?

Sustainable Development (SD) must be our way of living today and moving forward.  Wikipedia explains Sustainable Development as:  ‘a process for meeting human development goals while maintaining the ability of natural systems to continue to provide the natural resources and ecosystem services upon which the economy and society depend.’  Do a Google search and you’ll see there are many different definitions for Sustainable Development.  Since I like to keep things simple, we’ll break down Sustainable Development in Three Simple Ways:

“Three Pillars of Sustainability”
  • Environment
  • Society
  • Economy

Environment; ecosystem, ecology, earth.

We rely on earth and her ecosystems for life (air, water, food, shelter, etc.).  Therefore, as Earths dependents, we must all work together to always consider her and protect her and the natural resources she offers us.

Society; us, humanity, social equality.

We rely on earths natural resources (food, water, air, shelter) for survival and must, at all costs, protect and replenish her natural ecosystems while being mindful of humanities societal needs today and for future generations.  We, most of humanity, has also come to rely on our economic system and many of us are working toward economic growth for ourselves.

“Sustainability enables Earth to continue supporting our life.”

Economy; economic growth.

Economies are created and ran by humanity.  We know that humanity (society) depends on earth.  Therefore our economy must also depend on Earth and her many natural resources.  One definition of economic growth is, ‘an increase in the amount of goods and services produced per head of the population over a period of time.’  Economic growth must be re-defined and re-purposed being mindful of our environment(s) and maintaining and replenishing earths natural resources and ecosystems.  The updated definition of ‘economic growth’ should also consider an improved quality of life with less resource consumption and waste.

Solar Power vs. Coal…where do you want to live & receive energy from?

 

Sustainable development, simply put, is the process of meeting humanities survival needs (air, water, food, shelter) while maintaining and replenishing the environment and all of earths natural resources and ecosystems to improve human quality of life with decreased resource consumption balancing toward social equality.

Thank you for taking time and reading this information.  And please share this if you believe it may provide value to others.

Multi-Tasking Solar Modules: Photovoltaic Panels Used in All Situations, Environments, Shapes, Sizes, Colors, Locations

Solar Covered Parking, Photovoltaic Rooftop System

Electricity from solar modules can be produced anywhere on the planet, as long as the sun shines on it.  Solar modules are deployed around the globe today and being used in all different types of situations, locations, and for many purposes.

Solar Modules on side of building

One of the many benefits of solar energy is that the electricity that the system produces from the Sun is FREE.  So if you’re already paying a monthly electric bill to the utility company, instead pay that same money to yourself and invest in a solar system.

Solar Modules were originally used to produce clean, renewable energy.  Now they’re “multi-tasking” and are being asked to serve as vehicle shade structures, architectural building enhancements, overhead shelters, replacing building construction materials, to cover unsightly conditions, etc.  Photovoltaic panels are popping up everywhere and we’re only at the beginning of the solar energy production revolution.

Clear Solar Photovoltaic Modules

When considering going solar and changing from brown, dirty energy to clean, green energy, make sure to review all of your options.  Every site, building, facility has a unique location and situation.  A professional solar developer like AirUs Energy considers all of this as well as the products available on the global solar market to provide custom design solar solutions.

How solar power has changed over the last 10 years

Solar power is in a tremendously different place today than it was in 10 years ago. Below are a handful of impressive stats about solar power’s growth, as well as some general stats about solar energy potential that are also quite noteworthy.

1. Even yearly energy potential from sunshine dwarfs total energy potential from any other source.

The annual energy potential from solar energy is 23,000 TWy. Energy potential from total recoverable reserves of coal is 900 TWy. For petroleum, it’s 240 TWy; and for natural gas, it’s 215 TWy. Wind energy’s yearly energy potential is 25–70 TWy.

5. Germany accounted for nearly one third of global solar PV capacity at the end of 2012.

Italy (16%) and Germany (32%) combined accounted for nearly half of global solar PV capacity.

[Source: Renewables 2013 Global Status Report]

6. The price of solar PV panels dropped about 100 times over from 1977 to 2012.

Since 2008, the price of solar PV panels has dropped about 80%.

[Data Source: Bloomberg New Energy Finance / Chart Source: Cost of Solar/Unknown]

7. The sunshine hitting Texas in one month contains more energy than all the oil and gas ever pumped out of the state.

Nonetheless, New Jersey has about 10 times more solar PV power capacity installed than the entire state of Texas.

Solar PV providing light and power to Los Angeles; Santa Monica Pier and Venice Beach Graffiti Art Walls

Solar PV lighting system with Battery Back-up, Venice Beach, CA

If you’re paying attention to the skyline then you’ve seen solar pv arrays being used to provide clean, renewable energy popping up everywhere.  Many homeowners and business owners have made the switch from fossil fuels to solar power, but even the smallest of energy users (see photo left) are also making the move.

Solar Energy can be used anywhere on Earth the sun shines.  We use it to provide energy in remote locations where the ‘grid’ cannot reach as well as in ‘grid’ connected areas to help offset some of the utility company electrical demands.  A solar electric system in conjunction with battery back-up can produce clean, renewable energy throughout the day which can be distributed anytime, even during the utility companies peak charge times to save the most.  The solar lighting system installed at the Venice Beach Art Walls includes a battery back-up system at each light which allows the entire area to shine all night completely off the electrical grid.

Solar PV Array at Santa Monica Pier, California

Keep traveling a little farther north along the bike path and you’ll find the Santa Monica Pier.  Take a closer look (see pic below) and you’ll see a solar PV array helping push the roller coaster and ferris wheel along.  This solar system does not cover all the power required to run the Santa Monica Pier, however one of the many benefits of a solar system is it’s easily expandable.  As us about our proposal to take the Santa Monica Pier completely off the utility grid…

Go Green With a Solar Hot Water Heater, The Most Cost Effective Sustainable Option For Your Home Or Business

Many people in the U.S. can produce more than half their domestic hot water needs with a solar hot water system. In

Solar Hot Water Heater

Arizona and other southern regions of the US this can be more than 80% savings.  A solar hot water system costs more than a conventional water heater, typically between $7,000 and $8,000.  However, after rebates and tax incentives the cost to the client for a new solar hot water heater including a new tank is $2 – 3,000.  Homeowners may want to budget for routine maintenance on some units to include periodic checks on the pH of the system’s with glycol solution.

A gas water heater should never be used as the only tank in a solar hot water system. In a solar storage tank, water stratifies by temperature; cool water from the bottom of the tank is pulled up to the collectors on the roof to be heated then returned to the top of the tank. The colder the incoming water, the higher the solar collector’s efficiency. In a single tank system, the electric element or gas flame keeps the stored water hot, leaving no cold water available to send to the solar collectors. Solar hot water systems can be either active or passive. Most solar hot water systems use a pump to move fluid through one or two collectors. Thermosiphon systems, suitable for simple domestic hot water systems in frost-free climates, rely on natural convection to move water.

As mentioned above, in most cases, credits or rebates can defray some of the cost of installing a solar water heater and are available from local utilities or state and federal governments. Solar
