Energy sources like fuel and coal are limited and non-renewable, while human need for energy is constant. As such, scientists are inventing more and more chargers and batteries that use renewable form of energy.
The most widely researched and developed energy renewable energy chargers are wind and solar chargers. These devices capture the power of wind or sun, then store them until later use.Most green chargers are more expensive than traditional ones. However, given the fact that they use free and renewable energy sources to recharge, cost differences is recouped eventually. Households even save more money through reduced energy bill.
Green Chargers: Some Available Technologies on the Market
Like traditional batteries, the following chargers for the eco-minded are also portable. There are even more convenient to bring anywhere as they have no plugs and cords.
- Wind-powered chargers. Portable wind chargers are popular because they are cheaper than other green chargers. They also sport sleeker designs.
There are several ways to harness energy with wind-powered chargers. One is to hook the charger onto a bike when one is to go cycling. Another is to hang the device outside a window, especially during breezy days.
There are two models of portable wind chargers available today: the HYmini and Gotwind. On the other hand, people can also build their own wind-powered charger to recharge AAA batteries, radios, and other electronic gadgets.
- Solar-powered chargers. Solar energy is the most popular form of energy used to power gadgets as it is the most readily available. Compared to other green chargers, solar chargers are also more efficient and more flexible.
Many watches, calculators, cellphones, music players, and digital cameras can be charged using solar energy. There are solar batteries/chargers for bigger electronic gadgets such as laptops and notebooks, but they are rarer and harder to find. Solar panels come in a variety of forms, but backpacks and fold-up chargers are the more popular ones.
Renewable Energy Chargers: Some Design Challenges
- Lower efficiency. Renewable energy chargers are less efficient and have lower power output than conventional chargers.
- Costly. Manufacturers should also strive to make prices of renewable energy chargers compete with traditional chargers to make them more appealing for mass adoption.
