The Benefits Of Going Solar At Home – Guest post by Ryan McNeill

It’s official: Renewable energy is now the average American’s preferred energy solution, regardless of which side of the political spectrum they are on — and few renewable energy options are more accessible to the homeowner than installing solar panels.

The popularity of solar is skyrocketing, accounting for nearly four in 10 new electricity generation capacity additions in the U.S. last year. While utility solar accounts for a large portion of this new infrastructure, residential solar is also showing strong growth as more homeowners are realizing the many benefits of solar energy.

Why are so many homeowners going solar? Let’s take a look.


Economic Benefits of Installing Solar Panels

Once cost-prohibitive, solar energy is now more affordable than ever. Here are some of the reasons why:

  • Economy of scale. Due to increased demand, the cost of solar panels is now half what it was in 2008, and experts believe it still has room to drop.
  • Low maintenance. A high-quality residential solar installation can be expected to last 30 years or more. Very little maintenance is required, which keeps costs low throughout the life of the system.
  • Energy savings. Solar pays back big over time. The average solar customer saves $67,000 over the lifetime of the system — and that’s at today’s energy rates. Who knows what the savings will be as aging conventional energy infrastructure drives energy rates up in years to come?
  • Financing. Solar is an investment, but it doesn’t have to be a painful one. In addition to the energy-saving ROI of the panels themselves, there are many options available these days that make solar panels affordable to the average homeowner. Some of these include rebates, leases and low-interest financing options. Don’t forget that homeowners can still take advantage of the full 30 percent federal solar tax credit through the end of 2019.

Solar Performance Means Peace of Mind

Besides the obvious financial benefits, solar will set your mind at ease. Solar panels are remarkably reliable, cranking out electricity as regularly as the rising and setting sun. They are safe, too, producing no noise pollution or harmful emissions. And, many solar homeowners rave about the sense of liberation they feel when realizing they are no longer subject to the whim of “Big Power.” Those who own battery systems are even secure from interruptions to the power grid.

Global Benefits of Residential Solar

Choosing solar is simply the responsible thing to do, both for the planet and for the communities in which we live.

First, consider the environmental benefits. We all know the impact global warming is having on the planet, and that solar panels are a huge step in the right direction when it comes to reducing our carbon footprint. However, you might not be aware that solar panels are also water-friendly. Per kWh of electricity, solar panels consume 16-20 times less of this increasingly precious natural resource than the most common conventional forms of electricity generation.

Solar is good for people, too. Dollar for dollar, an investment in solar results in twice the job creation as conventional energy sources. And, solar is an important factor in homeland security. Solar panels reduce dependence on foreign energy, reduce the electrical grid’s vulnerability to attack or failure, and provide an excellent source of power in emergency situations.

Is Solar Right for Your Home?

While not every home is suitable for solar, the benefits are clear for those that are. It’s no wonder so many more people than ever are choosing to install solar panels on their homes.

Water and wastewater (WWW) treatment – a look at the energy used for water in the US

While water and wastewater (WWW) treatment accounts for a surprising 5% of total U.S. electric power generation, topographically-variable WWW conveyance account for a more surprising 15% of the same total [Pod06; Coh04]. In addition, while wastewater contains energy in dilute form, current goals for recovering such energy represent only 0.02% of the total generation, through the use of microbial fuel cells of the future [Log04]. If, on the other hand, WWW were decentralized, up to 15% of total U.S. electric power production could be saved.


While centralization of WWW treatment was implemented to concentrate resources and ensure water quality, today many monitoring, quality control, and operation and maintenance (O&M) functions can be decentralized electronically. Imagine, if each building of the future contains a direct potable reuse system, then maintenance personnel, rather than driving to a central facility daily, would be dispatched electronically to neighborhoods for routine annual maintenance. Moreover, decentralization would increase the accountability of neighborhood residents in terms of responsible use of water, personal care products, and household chemicals.


Beyond energy savings, autonomous net-zero water (ANZW) buildings would not need to treat for most pesticides (US, 5 billion lbs/y) and industrial chemicals (US, 6 billion lbs/y), representing a total mass loading of 2 mg/L on U.S. surface and groundwater runoff. Treatment instead would focus on effective destruction of endocrine disrupting compounds (EDCs) such as pharmaceuticals, which cannot be as easily regulated in terms of environmental half-life as pesticides and other chemicals, by advanced oxidation. This latter advantage would address the current 6% feminization of male fish across all species (20%, black bass) in U.S. river basins [Hin09]. Finally, an urban demand for e.g. one million gallons of water every day in Southeast Florida would be removed from the (Everglades) natural system. Eliminated would be water rationing, and the need to treat seawater with total impurity levels two orders of magnitude higher than drinking water standards, to drinking water standards when impurities in treated wastewater e.g. in S. Florida currently meet 87 of the 93 numerical drinking water standards on average without further treatment.


Increased construction activity in the outlined areas over the last 10+ years. Many infill projects and zero lot line developments. Increased population growth in the target area with increased load (people) and demand (use per individual). Overall individual load has increased over X years by X gallons per day. Strain on water treatment system and infrastructure, especially close to water ways cited. Septic tanks systems that are undersized, outdated or broken, without eh owner knowledge. Purposeful (non permitted or documented) re-routing of sewage water to nearby water ways and excess burden on municipal sewer system with surface water runoff, increased rainfall intensity and more man-made diversions of water. Quantity of subsurface runoff (stormwater).


Estimates of water use in the United States indicate that about 410 billion gallons per day (Bgal/d) were withdrawn in 2005 for all categories summarized in this report. This total is slightly less than the estimate for 2000, and about 5 percent less than total withdrawals in the peak year of 1980. Freshwater withdrawals in 2005 were 349 Bgal/d, or 85 percent of the total freshwater and saline-water withdrawals. Fresh groundwater withdrawals of 79.6 Bgal/day in 2005 were about 5 percent less than in 2000, and fresh surface-water withdrawals of 270 Bgal/day were about the same as in 2000. Withdrawals for thermoelectric-power generation and irrigation, the two largest uses of water, have stabilized or decreased since 1980. Withdrawals for public-supply and domestic uses have increased steadily since estimates began.
