NYC can lead the solar energy revolution

Imagine capturing all the solar energy that beats down on New York’s rooftops every day. We could power our homes, schools, offices and even our cars, buses and trains with clean and virtually limitless sunshine. #solarenergy  #solarpower  #energy  #solar  #australia  #solarpanels  #gogreen  #actonclimate

Solar and clean energy jobs easily outpace oil sector

Just in case anyone thought Tesla Motors chief Elon Musk couldn’t get more ink in these pages, he appears to be at the center of a trend that can complement his electric-vehicle development. Musk’s SolarCity solar-panel distributor competes in a green-energy sector that’s now said to be growing far faster than old-line natural-resource sectors like oil and coal

The Types of Solar Electric Systems

Electric systems have been created because of the rise of solar power as a reliable and cheap source of energy. There are now different techniques, methods and systems that depend on solar power to run plants, houses and offices effectively. You should learn more about these systems to determine the best types that will provide you with the most benefits. You can choose to make your own or just purchase one from top manufacturers.

The Stand Alone System

There are small stand-alone electric systems that are very good at giving economical electricity. These systems are mainly used to power RV, lighting, backup power systems, portable power systems and cabins. The size of the array of photovoltaics or the number of solar panels, as well as the battery will rely on the individual power requirements.

The solar panels charge the battery during daylight periods and the battery will provide power to the inverter whenever required. The inverter transforms the 12 volt batteries DC power into 120 volt AC power. This is the most useful kind of current for majority of applications. The charge controller will terminate the charging once the battery reaches the full charge. The batteries will not gas out this way and battery longevity is enhanced.

Grid-Tie Solar System

The grid-tie solar system is very useful for homes that are already linked to the utility grid. The primary advantage of this kind of system is the cheap price of utility. The system needs to be wired with an inverter that creates pure-sine-wave AC electricity, which is needed for linking to the utility grid. Another benefit of this electric system type is the tax incentives. There are also rebates provided depending on the local agency and the state.

If you own a grid-tied system in California, you can make use of some programs that will minimize the total cost of the system. Majority of the system usually do not include the battery storage that lets power in once the utility does not work. Grid-tie systems are installed using battery backup power to maintain critical loads even in the presence of a power failure.

The Full Stand-Alone

The complete or full stand-alone system is very useful for complete independence from electric utility companies and fossil fuels. The benefit of the system is the capacity to provide power away from the utility, as well as creating a measure of self independence. The complete stand-alone home solar system will usually have a couple of inverters to supply the AC house current needed to power very big loads like air conditioners.

An available second inverter will help make sure that power is present if one of the inverters will need servicing. Self-contained systems like these require an adequate battery keeping capacity to give electricity when solar power is not available because of prolonged adverse weather conditions. The complete stand-alone system usually needs 20 solar panels for safe battery keeping and adequate charging. You may ask an expert to help you decide between systems to that you get the most out of your investment.

Saving Energy without Breaking a Bank

Energy is not just the monthly bill you have to pay each month; it is the foundation of everything you do and the life to everything you have. But with the increasing cost of energy, it cannot be denied that we need to take important measures to limit our energy consumption. Saving energy becomes a must and a habit that everyone should seriously adapt.

Heating and Cooling.

Almost half of your electric bill goes for your heating and cooling systems so if you really want to maximize your savings here are the following things you can do:

Clean your air filters at least once a month.

Clean baseboard heaters, radiators, and warm-air registers as often as necessary; make sure that they are working properly; and that they are not blocked by drapes, carpeting, and furniture.

Set the thermostat as high as is comfortable when it is hot or as low as is comfortable when it is cold.

Turn off exhaust fans (kitchen, bath, others) 20 minutes after cooking or bathing. Keeping them on for a long time affects the temperature of the room.

Lighting and Appliances

As much as possible, use natural lights – working near the windows will prevent you from turning on the light and consuming energy. Utilize the power of the sun.

Switch off the lights every time you leave the room even if it is just of a minute.

If you are using the 4-foot fluorescent lights, install reflective backings to maximize the light.

Switch to compact fluorescent lights. There are 4-watt minifluorescent lights and 40-watt fluorescent lights have the same illuminating effect.

Turn off all lights and appliances when not in use. Unplug unnecessary appliances like microwaves, television, stereos, computers, and VCRs if you are not using them. Also, unplug chargers and devices with bloc-shaped transformer on the plug. All of them consume energy when plugged in. Do not leave them on “stand-by” mode.

Look of Energy Star label when purchasing lighting product.

Use task lighting instead of lights that cover the entire room. For example, use lamp shades when reading and not the lights for your room.

Laundry

Washing your clothes cold will reduce washer’s energy consumption by as much as 90%. Air drying eliminates the energy use for machine drying.

Always do full loads whenever possible. If you are washing a small load, use appropriate water level and wash setting.

Refrigerator

Maintain a right temperature for your freezer and refrigerator.

Do not hold the refrigerator or freezer open. The energy consumption increases if the motor works endlessly just to maintain the temperature of the refrigerator and freezer.

Check for leaks and cracks in the gasket. Make sure that your refrigerator is completely sealed to maintain the temperature inside.

Insulation

Heat loss happens when your house is not properly sealed. Use sealants or weather-stripping on windows.

Make sure that air cannot escape or enter in to the pipes, doors, walls, floors and ceilings. A properly insulated home saves as much as 10% in electric bill.

In a typical household monthly electric bill, 44% goes to the heating and cooling systems; 33% goes to lighting and other appliances; 14% goes to heating the water; and 9% goes to the refrigerator. Take note of this power distribution to know where exactly you can maximize your saving.
