Solar energy is more efficient than electricity in the long run, but initial costs are higher. Availability and surface area are challenges, but solar technologies are advancing. Tax credits and rebates make solar more affordable. Homeowners have many solar choices for heating, cooling, and hot water systems. Businesses can benefit from lower operating costs and protect air quality. Achieving solar energy efficiency goals leads to more jobs.
Solar energy efficiency decisively beats electricity if the buyer can afford higher initial costs. Many homeowners looking for a new heater, for example, aren’t willing to pay five times the money for a solar system when electric heaters are so much cheaper. In the long run, however, solar energy is much more efficient than electricity. Over time, once the upfront costs are paid, using solar saves more money and is more energy efficient.
The advantage of electricity is its availability. Some solar-powered products require sunlight to shine through to function. On overcast days and cloudy regions of the world, solar energy cannot be counted on as often as it is in sunny, warm climates. Furthermore, large surfaces are usually needed to harness the sun’s heat and provide energy. However, solar technologies are becoming more advanced and facing challenges. Solar remains the cleanest source and is cheaper in the long run.
Today’s economy offers a favorable environment for the transition from electricity to solar energy. Federal tax credits are available in the United States, as well as various utility rebates and rebates by state or country. Monthly comparisons of energy use and bills demonstrate substantial savings after solar system installation.
Homeowners have many solar choices for heating, cooling, and hot water systems. Heating and cooling interior spaces consumes more energy than any other component in the home. Active solar heating involves the heating of liquid or air in a collector device. Passive heating and cooling both use the building design to control temperatures. Solar heat can also generate energy for a cooling system.
Producing heated water is also a major cost, although less energy is required than heating and cooling the air. Solar water heaters are gradually decreasing in cost. Solar energy efficiency can be achieved by an active or passive solar water heating system. Basically, the sun’s heat is collected in the solar collectors and heats the water in the storage tanks. Active systems use pumps; passive systems do not.
Businesses around the world are considering solar energy efficiency as a way to save money and show concern for the environment. Solar mirrors on a large office building can heat water pipes and cool the air in interior spaces. Some businesses benefit from lower operating costs by taking advantage of solar energy efficiency. By using solar energy as an alternative energy source, nations around the world are less dependent on other fuels, protecting air quality. Achieving solar energy efficiency goals also leads to more jobs, as skilled workers are needed to manufacture, install, and maintain solar products.
