Arizona Stands Up for Solar Rights


 By Annie Lappe
 
In a  victory of David vs Goliath proportions, policymakers in Arizona stood up for its citizens by rejecting an attempt from the states largest utility to squash rooftop solar. Five months after Arizona Public Service (APS) sought approval to slap hefty new fees on its customers that go solar, the Arizona Corporation Commission (ACC) voted yesterday to uphold Arizona solar savings and energy choice. While the vote was clearly a win for Arizonans, the ACCs approval of a small but troubling new fee makes it clear that there is a significant amount of education left to be done regarding distributed solars tremendous value.

Driving this proposal was that fact that solar is offering customers an affordable new energy option, and Arizonans are increasingly choosing to generate their own power from the sun. Rather than working with its customers and meeting this new market demand, APS attempted to dig in and regulate against competition to maintain its monopoly hold on electricity.

APS Proposal Denied

APS had proposed a new $50-100 monthly charge for solar customers, a discriminatory fee that would have wiped out any savings these customers would currently receive from their solar investment. APS justified the solar fee by saying that net metering a program that ensures solar customers receive full retail credit for power they deliver to the grid for their neighbors to use is a bad deal for Arizonans but thats just not true: private investment in reliable, local power generation benefits all ratepayers. Full retail net metering credit is a simple and proven way for customers and utilities to assign value to that power.

A study conducted this year for SEIA showed that these net metered systems actually deliver much more: $34 million in annual net grid benefits for APS customers alone. Thats before accounting for the social and environmental benefits: cleaner air and thousands of local jobs. APSs proposals were clearly not grounded in a fair accounting for DG solars real value, and our allies argued strongly in favor of undertaking that fair accounting in the appropriate venue: the next rate case.

Despite millions of dollars on spent on a misleading campaign by the utility and its proxies, public outcry against the APS proposal was overwhelming. A poll conducted last week found that, even after months of being blanketed by utility ads, a whopping 81% reject APSs solar fee and 77% would be less likely to vote for a candidate who ends solar savings. Over the course of this long campaign, more than 30,000 Arizonans emailed the ACC in support of rooftop solar.

Arizonans Show Up to Support Rooftop Solar

That support was demonstrated in person earlier this week when 1,000 Arizonans gathered in front of the ACC this week to protest APSs proposed fee. Inside a steady stream of about 100 citizens solar workers, solar customers, non-solar customers, environmental advocates, retirees, veterans, even one passionate 11-year old girl urged the Commissioners to stand up against the utility for the good of Arizonans. Yesterdays vote is a resounding demonstration that the peoples support of solar trumps corporate money. It showed just how out of step APSs anti-solar efforts are with the needs and demands of its own customers, and we were pleased to see Commission acting on behalf of the public they serve.

Interim Fixed Fee Adopted

Its important to note that while the most egregious aspects of APSs proposal were soundly rejected, the Commission did vote by a 3-2 vote to implement a relatively small but still unjustified new fixed fee of $0.70 per kilowatt as a monthly charge for all new residential solar customers (i.e. if you have a 5kW system on your house, you would pay $3.50 a month). The vote broke down as follows: Commissioners Stump, Bitter-Smith and Bob Burns voted yes, and Commissioners Pierce and Brenda Burns voted no, arguing that the fixed fee was too low.

The fee will be collected through the Lost Fixed Cost Recovery (LFCR) adjustor mechanism. APS is already using the LFCR to collect funds from customers to account for the fact that the Company is losing money when customers invest in energy efficiency or DG solar.

The new fixed charge will stay in place until APSs next general rate case, which must be filed in June 2015. However, the Commission did add a clause that allows the ACC to periodically adjust this charge in any APS LCFR reset proceeding, which happen on an annual basis. During the next rate case, net metering will be addressed in more detail.

Existing solar customers will not be assessed this charge, and will be grandfathered under their current rate structure arrangement, at least until the next rate case, though verbally several Commissioners expressed intent that they would be grandfathered from the charge in perpetuity. However, all rooftop solar customers, including existing customers, will soon need to sign a disclaimer that acknowledges that rates can change in the future.

Workshop Process Established

In the interim between now and the next rate case, the Commission has also decided to hold a series of workshops to determine the true costs and benefits, and any associated cost shift, of net metering.  Vote Solar looks forward to participating in this process and making sure that individual solar investment is properly valued.

We strongly disagree with the Commission that net metering represents a cost to non-solar ratepayers, and we hope through the workshop process facts can be brought to the table to dispel this myth once and for all. Rooftop solar is helping Arizona families, schools and businesses take charge of their power supply and their electricity bills like never before. This private investment is helping build a cleaner, safer and lower cost energy supply for all of us.

Nanoleaves; Technology Breeding New Ways To Harness Energy


In a relatively modern field, known as “Biomimicry”, nanoleaves are being construed to harness renewable energy. These “leaves” are attached to artificial plants and trees to capture solar energy. The nanoleaves are constructed with miniature thermovoltaic and photovoltaic modules that absorb the light and heat provided via solar energy, and thereafter converts it into electricity.

Overview of Nanoleaves Technology
One of the emerging nanotechnologies related to renewable energy is nanoleaves and stems of artificially created trees or plants. They are intended to harness energy provided by the wind and sun, thereafter converting it into electrical energy. Moreover, to better understand the fundamental of nanoleaves, we have to dig into an innovative field of technologic development, called Biomimicry.

Overview of Biomimicry Technology
The nanoleaves have been specially designed to imitate the natural process of photosynthesis. A mechanism by which, typical plants absorb the light emitted by the sun and CO2 in the atmosphere. The artificial trees do even copy the natural re-cycling process of oxygen. It is very recent that nanoleaves technology started to reap even more advanced levels. It can now harvest thermal energy as well. Moreover, the leaves fixed on artificial trees are also able to collect energy derived through movement of the wind, known as kinetic energy, which is as well converted into electrical energy.

Compositions of Nanoleaves
The nano-technology was initially developed to harness solely solar energy. However, nowadays it has widespread uses. It exploits various alternative sources of energy like wind, solar and thermal energy. Furthermore, these highly advanced artificial plants and/or trees use tiny cells to capture energy:

Thermal Energy - Tiny thermovoltaic cells are used to capture thermal energy via semi-conducting material which converts the heat into electricity.

Light Energy - There are also tiny photovoltaic cells (PV) incorporated in the nanoleaves. These small PV cells capture the light rays emitted by the sun. The light is then converted into electricity.

Kinetic Energy - Kinetic energy is harnessed through movement. The wind produces motion in stems and branches. This motion is collected via piezovoltaic (PZ) cells. The PZ has semi-conducting devices incorporated into the artificial structure of trees and plants. The PZ and the semi-conducting devices convert typical wind energy (kinetic energy) into electricity.

Best Places to use Nanoleaves
The use of piezvoltaic, thermovoltaic and photovoltaic cells does effectively convert an amalgamation of energy sources into electricity. Artificial energy trees can be used for both domestic or even industrial purposes. According to Solarbotanic, erecting an approximate of six meter area of nanoleaves can produce enough energy for an average household. More, intricate is that, artificial trees can be constructed at various areas, like;

Desert - The earth has large areas of unexploited deserts which can be used to generate a massive amount of electricity, if artificial trees were planted. The energy produced could be used to solve the most predominant challenge in desert; provide electricity to power desalination. The desalinated water could thereafter be used for irrigation and drinking purposes. The fragile desert environment would hardly be affected by such a project yet the benefits are extensive. To further minimize the environmental impact on desert, the artificial trees could be planted alongside roads, coasts and other areas where it would protect inhabitants from sandstorms and provide constant shade form the sun.

Golf Courses, Recreation Grounds and Parks - Artificial golf courses, recreational grounds and parks could have artificial plants and trees planted to supply electricity for at least a portion of recreational parks. For golf course, the nanoleaves could fuel ground maintenance vehicles.

Office Parking and industrial Zone - The multi-fold benefits of planting trees near office parkings and industrial zone are numerous. It provides with electricity to office, parking lights and other uses. Moreover, it does also provide with shade from the sun and offers an aesthetic landscaping.
