Battery packs make the use of environmentally friendly sources of energy available when and where it is needed. The renewable energy from the sun and the winds can be used on a dark or still night because what has been harnessed during the day can be stored. There are several sizes and types of battery packs available to store the natural energy so that it is available when needed. The scalable power means that almost any need for environmentally friendly energy can be met.
Business and governments are relying on battery packs that have been charged with energy from the wind and the sun in increasing numbers as the call to reduce dependence on dirty, non renewable fossil fuels is answered. Lighted signs along the road that alert drivers to a hazardous situation depend on the use of battery packs for operation. Portable lighting for construction in remote areas also depends on the storage systems. Lights on billboards and on top of buildings are often energized by the battery packs, as are parking lots and bike trails.
The battery packs can be used indoors as well as outdoors, making it convenient to light up areas in a building without a source of electricity. Outbuildings, driveways and even garden paths can all be lit with environmentally friendly power harnessed from nature. Battery packs designed to store natural energy can be used even in places that rely on a power grid as the main source of energy. When the lights go out because of a storm or other cause of failure, emergency lighting and energy will be available to provide a safe, well lit area for homes and businesses.
The use of battery packs has made the use of clean energy a more reliable and convenient option for many home and business owners. Instead of being limited to the availability of natural power dependent on the weather, the energy collected and stored can be used on an as needed basis. Once it was only possible to use energy derived from the sun, or solar lighting, during hours of direct sunlight, making many consumers wonder if it was worth the expense of installing solar panels. The same was true for wind power. If the breezes came from the wrong direction, or if there was a calm period with no movement of the air, the wind turbine stood useless.
