Dangers of Renewable Energy Wastes Build-up

Renewable energy is still on the rise to make itself the go-to source of energy for the planet. Despite recent leaps in renewable energy development, the industry still faces a significant hurdle, namely the intermittent nature of sustainable energy. Renewables largely depend on batteries as a storage option for large amounts with systematic releases when the demand arises. This makes the source of energy largely dependent on batteries as a source of power backup.

Renewable energy depends on the continuous supply of climatic variables like sunshine and wind to generate power. However, finding a near-continuous supply of these sources of energy is nigh impossible. Resultantly scientists opt to use batteries as a demand buffer for energy when needed. According to Aceleron CEO Amrit Chandan, energy storage is the most sought-after commodity in the energy market.  This results in a rising demand for efficient battery and storage devices 

Following this trend, high capacity batteries are in high demand, especially in the utility, manufacturing, and transport sectors. The sector initially depended on lithium-ion batteries. These were batteries used for small scale applications lie remotes and household activities. However, the batteries are now being developed to hold more capacity for industrial purposes. Research into lithium-ion batteries will get additional investment towards developing high energy and high capacity. A recent venture raised 3.2billion for research and development of lithium-ion batteries with backing from companies like Tesla and General Motors. 

The disposal of rechargeable batteries waste is a major issue for discussion. This is especially important when it contributes heavily to the successful adoption of sustainable energies. If left unchecked, these disposals will reach close to 11 million tonnes worth of wastes by 2030. The figures represent lithium-ion battery wastes disposed of in the electric vehicles. Experts report that such levels are enough to fill Wembley Stadium 20 times. This predicament presents a huge and increasing issue that needs to be controlled. Likewise, the rise of sustainable power for transportation and other battery-driven products also increases the demand for batteries increasing the total attainable waste figure.

There is rising concern over the overlaying dangers of renewable energy wastes and the dangers they pose for the environment. Experts in waste management relate that the wastes from renewable energy sources and systems reduce but still substantially comparable to wastes realized from internal combustion engines. However, there is a need for manufacturers to find ways of making batteries recyclable or maximizing the efficiency of batteries and components
