Solar electrical-generation technology is about to go mainstream thanks to a multi-state consortium of energy producers in the American Southwest. Combining solar and electricity into a single concept tends to elicit visions of sun-bathed photovoltaic panels, but in this case, the sun’s energy will power a more conventional steam-turbine plant by focusing the sun’s heat. The technology, sometimes called concentrated solar power (CSP), employs mirrors to redirect ambient solar radiation collected over a widespread area on a heating element of much smaller area. In smaller-scale models, CSP has proven itself more compact and efficient than virtually any other alternative energy source at the time.
The Southwest Energy Service Provider’s Consortium for Solar Development is soliciting proposals for a 250-megawatt solar thermal power plant by 2012 in either Nevada or Arizona. All of the power produced will be purchased jointly by the consortium members.A multi-state utility consortium in the southwest United States is in the planning stages of building a large-scale solar power facility in the region.
The consortium’s parameters specify the plant must employ concentrating solar power technology, which focuses the sun’s rays using trough-shaped mirrors, dish-shaped mirrors or a series of flat mirrors that in unison track the sun’s movements. The consortium also prefers a facility with thermal energy storage.
Consortium members include the Arizona Electric Power Cooperative, Arizona Public Service, the Southern California Public Power Authority, the Salt River Project (provides power to Phoenix), Tucson Electric Power, and Xcel Energy (serves eight states in the West and Midwest). Arizona Public Service is coordinating bids and proposals.

Home security is on the minds of everyone these days, as Americans are increasingly feeling more vulnerable and haunted by worries about leaving their homes unattended while they are at work or on vacation. Nowadays, deadbolts and a Doberman aren't enough to deter criminals as they can easily get past such home security measures, and professional thefts know how to bypass your basic security. You actually have to fight to keep them out and do what you can to secure your own little part of the world by enhancing your home security.
In case you don’t have a home security monitoring system, you may not be aware of the various options that are available to you. And even if you already have one, you still may not be fully cognizant of the options available beyond your current home security system. There is a raging war between highly skilled burglars and the minds behind security systems. Experts in home security systems make use of highlysophisticated technology, and employ cutting-edge techniques to fathom the psychology of burglars and criminals. Although home security systems are not entirely foolproof, they somehow help minimize the risk of crime and burglary considerably. Make no mistake about it, having a good security system installed in your home can do wonders for your peace of mind.
Technological advances have made home security into an art form. There are plenty of home security shops that offer a wide range of products to protect your home and family. Current trends in home security involve the use of alarms, locks, motion sensors, safes, and personal safety devices. Security alarm systems come as either wired or wireless, and they make great deterrent for criminals. They keep an eye on points of entry such as doors and windows and they are activated by the any signs of break-ins. Windows are the favorite points of entry because they are made of breakable glass. However, there are security alarms that can detect when glass is broken, setting off an alarm that will send the intruder away.
Motion sensors monitor and detect any unauthorized movement when your house is supposed to be empty. Modern motion sensors can even distinguish between a pet and a criminal, making this security system even more effective. Good lighting in and out of your house is a good enough deterrent but you can save power by installing security motion sensor floodlights that only activate when motion is detected.
Security cameras are quite popular among business owners and other commercial establishments. They are also fast becoming a popular choice among homeowners. A home security camera monitors and records activities going on anywhere around your house 24/7. Security cameras can also be installed so they can provide a view of your front door. This allows you to check the television monitor and identify who is at the door if your doorbell rings. Cameras act as an excellent deterrent and are very useful in the prosecution of criminals since they are caught in the act.
You have a lot more options in security systems. It is imperative that you make all effort and spare no expense in protecting your home from theft. It is always advisable to invest in a good home security system instead of leaving yourself susceptible to crime. Burglars usually think twice about breaking into a house outfitted with home security products, so an effective home security system is a good deterrent against these criminals. When you finally decide to install a home security system, the first thing you need to do is to find a professional and reliablehome security company that can provide you with the most suitable security products for your home.
It is worth mentioning that family finances are among the hardest-hit by the global economic downturn. The crisis has prompted households to take the matter of budgeting seriously. Today, families are adopting cost and energy saving methods by considering different ways by which utility bills paid to the power company every month can be reduced to the barest minimum. Many homeowners are likewise employing tools that can help in monitoring home energy use.
Fortunately, the government issued the stimulus package and renewed public attention to energy savings. A number of companies saw the need and pounced on the opportunity to develop and eventually market wireless energy dashboards that can be used to keep track of energy data from your power meter and inform you if you’re being an energy hog. In addition, President Obama pledged to help utilities install an additional 40 million smart meters. Such meters are essentially digital meters that create a 2-way connection with the utility and the power grid. Smart meters can provide data about the fluctuating cost of electricity throughout the day, allowing consumers with energy management tools to switch power consumption to the time of day when energy is cheapest.
Utility meters are great measurement tools so try to get into the habit of reading the electricity meter on a daily basis. Monitor your energy consumption on a graph or in a spreadsheet and track changes or fluctuations. In case your daily readings spike, try to pinpoint the cause. Spikes in usage serve as a warning that something needs to be checked. And when your daily readings begin to fall consistently over time, you know you’re doing something right in terms of saving energy.
There are also plug-in electricity monitors that can help you determine how much electricity a certain device or appliance consumes. You simply plug the device into the meter, and it shows readings for watts of power used, including kilowatt hours over a period of time. These meters can be used to gauge how much electricity you're losing to phantom loads like AC to DC converters or anything with an LCD or LED display. Such devices can use up power even when nothing is plugged into them. You can also use plug in monitors to correlate actual electric consumption of an appliance to what the manufacturer's claims say. If they don’t match, then you can make the necessary adjustments as to the settings or configuration of your appliance.
Another category of tools is the full-house electricity monitors which can track your home energy consumption in real time so you can examine usage change as different appliances are turned on and off, thereby identifying those that require the most power. However, these monitors are more expensive and not as useful as plug-in monitors in determining how much power a given appliance uses. Aside from the aforementioned tools, there are a lot more available in the market as more companies try to find ways to help save energy while saving the environment at the same time. In the end, what really matters is for all of us to be eco-conscious and help raise awareness about the importance of saving energy
