Technology is moving fast, and everyone is yawning to be in the mood of moving with it and that is the reason even the energy sector is not left behind. For many years, gas and oil industries have dominated the market in the renewable energy field. Every day every hour oil or gas is used, but technology is taking this sector to another level with the introduction of Solar-PV and Wind-Turbine. The system is gaining momentum across the globe, and everyone appreciates it though it does not operate the same way as other systems because it depends on energy storage systems. In subsequent paragraphs, we will look at the positive and negative aspects, the commercial availability, and the impact on the environment during the usage and the cost – effective recommendations of energy storage systems.

The followings are the positive and negative aspects of energy storage systems: They are renewable; means when you use the system, you will never miss out power especially when you are using solar as compared to oil and gas and other non-renewable sources (Maehlum and Mæhlum, 2012). As long as the there is the sun; you will continue having a stable supply of energy. The second positive aspect is abundance; you will always get enough of the energy required. Earth receives more than 120,000 terawatts of radiation (Iqbal, 1984) which is 20,000 times than the regular supply of energy required. The third point is that, they are sustainable; it means, when you are using mainly solar power you will always get enough, no time you will miss solar, and that is how it is easy to sustain, you do not need to spend some little more to pay for the sun and you cannot over-consume. It does not end there; energy storage systems are environmentally friendly that is to say, there are no pollutions caused when you are using solar for instance, you are always assured of your health (Gibson, 2004).  Energy storage systems are available, you could not struggle to get them, and they are everywhere in shops and approximately every country (Energy and United States. Dept. of Energy., 1995).  They are easy to install; for instance when you are using the battery, you do not need an expert to come and fix it for you, as long as you know how to read to can set your battery (Chen et al., 2013).  They reduce costs for electricity; it means when one is using Energy storage systems will never experience the same burden of power bills (Zavalani, 2011).

As much as we have talked much on the positive side of using energy saving systems, there is a negative aspect. For instance, when you opt for solar you must analyze the depth of your pocket that means it expensive for an average income earner to afford (Zydeveld, 2000). The other limitation is intermittent; every time you use solar energy, for instance, you have a check on the weather. Intermittent means the system is limited to some weather conditions like night and morning (Maehlum and Mæhlum, 2012). Even though the system is termed as environmentally friendly when using it, its manufacturing process is related to greenhouse gas emissions (Tian and Qiao, 2013).Lastly, it requires space as compared to the oil and gas.

The systems are available commercially everywhere around the world. For instance, solar panels can be found even supermarkets and they more reliable than batteries.

Solar batteries and other energy saver systems are termed as the best and friendly to the environment, but they have another dark side. Air, water, climate, land, landscape and wildlife can be damaged by conventional generation that also raises the rank of harmful radiations (EC,1995,1997). Regardless of the way that the era of solar thermal (ST) structures requires sensible measures of materials, insignificant totals are moreover exhausted in the midst of their operation; around then the principle potential usual poison rises out of the coolant change, which can be adequately controlled by awesome working practice. The incidental spillage of coolant structures can realize fire and gas releases from vaporized coolant, unfavorably impacting general wellbeing and security. On the contrary, the massive scale plan of ST developments will on a very basic level reduce the ignition of general powers and will along these lines; diminish the average impacts related to these fuels  (Tsoutsosa, Frantzeskakib, and Gekasb, 2005) . Energy saver systems (photovoltaics, solar thermal, solar power) give gigantic common points of interest in the examination of the official essentialness sources, thus contributing, to the possible change of human activities. Sometimes, however, their apparent scale association needs to face potential negative environmental repercussions. These potential issues seem, by all accounts, to be a substantial obstacle for a further scrambling of these structures in a couple of purchases  (Spellman, 2014).

Another example is batteries; Batteries are recognized as an issue material in the waste stream. Batteries are delivered utilizing a combination of chemicals to control their reactions. Some of these chemicals, for instance, nickel and cadmium, are to an extraordinary degree hurtful and can make mischief individuals and the earth. In particular, they can realize soil and water defilement and imperil untamed life. For delineation, cadmium can cause damage soil small scale life structures and impact the breakdown of particular matter.  In like manner bio-total in fish, which diminishes their numbers and makes them unfit for human usage. Exchange Landfill is all things considered where batteries wind up. Regulations speaking to battery move contrast in each state and space in Australia. In Western Australia, both unnecessary and rechargeable batteries are classed as hazardous waste; they are placed in steel drums encased in bond inside secure landfills so that air and water cannot dissolve the battery lodgings. In Queensland, by connection, people hurl batteries in the canister with an exception. The primary batteries in a matter of seconds reused in Australia are the lead-destructive batteries that power our cars and trucks; more than 90 for every penny of which are reused. The exciting news is that moves are in advancement to develop family battery reusing. In Melbourne, a trial of a independent reusing organization for family unit batteries began in mid-2007. The organization is a joint movement between the Government and industry to give places where people can drop off their dead batteries (OECD, 2005).

Foreseeing through 2050, the report looked at the money related parts of three setups in five urban zones—Los Angeles, Honolulu, San Antonio, Louisville, KY and Westchester, NY. Besides, saw a ton of elevating news. It found that the most traditionalist structure for the customer advanced after some time from the cross section just, to arrange notwithstanding daylight based, to framework notwithstanding the sun controlled notwithstanding battery. In three of the five urban regions, the system/universes were financially profitable to purchasers today, and they would be so in each of the five civic groups within ten years. The report moreover found that structures that included battery stockpiling would be preservationist in three of the civic groups within 10-15 years (Pantsios et al., 2015) .

It in like manner observed that, paying little regard to whether the structure fused the stockpiling battery, customers’ reliance on imperativeness from the system decreases after some time, especially as the cost of force from the grid augmentations and sun arranged and battery costs reduce (MacGill and Watt, 2015).

“Amazingly, the examination shows that system joined Sun situated notwithstanding battery structures get the chance to be monetary for generous amounts of customers, and those systems can supply more foremost and more distinct parts of customers’ energy,” said the report.”Assuming customer allocation takes after full money related matters, the degree of a potential kilowatt hour (kWh) abandoning from the grid in large  (Sumathi, Ashok Kumar, and Surekha, 2015) .

Energy saving systems is a technology that has come to stay. Many people have started using it entirely in their homes. As much as we could have some negatives aspect, it has more positives.
