Green energy technologies are assured to make an immediate impact on energy supply and access in the developing countries. By making use of renewable resources, developing countries can reduce the dependence on oil, gas, and electricity, creating energy portfolios that are less vulnerable to price rise.
There are several products in the market today, and several innovations that can allow people in the developing world to have a cleaner lifestyle without having to spend huge sums. Solar power is a great benefit in such cases, as people don’t have to rely on electricity and utility supply, which often is erratic at best in the developing world.
LuminAid Solar Light
This relief giver light has a Lithium-Polymer Ion battery that helps to increase the energy storage capacity and quality. LuminAid Solar light provides up to six hours of LED light, helpful in giving relief to the people during natural disasters. This lantern is solar rechargeable, lightweight, inflatable and is waterproof. These useful features of this solar light allow it to be more sustainable, affordable and accessible.
Eliodomesticao Solar Still
Designed by Gabriele Diamanti , the Eliodomesticao Still is an intelligent design that was made keeping the requirements of the developing world in mind. It is made from the widely available materials and is simple and inexpensive. The Solar Still is easy to use and looks quite like an upside down coffee maker, albeit made for water purification. It does not rely on water filters or electric supply, and can have the sun do all the work.
You just have to pour water on the top of the equipment, and it will get to work. The heat of the sun converts the seawater into steam resulting in rising up the steam pressure into the water tight boiler. The steam travels down through a nozzle and condenses against the lid. The machine can provide 5 liters of potable water every day.

Princeton University student, Eden Full has developed a cheap and recyclable Sun Saluter. Solar panels on the device track the sun to gain about 40% energy efficiency. This innovative device is a great relief to the under developed communities and provides electricity and purified water.
Portable Light Project
Portable Light Project has flexible photovoltaic cells weaved into the bags. During the day, as the users continue their daily tasks, the panels on the bag absorb the solar energy to power a battery. The battery charges in six hours, and can theoretically power a small light for about 20 hours.

The SunWater is one such project that is best suited for the people who are totally dependent on farming for their income. Behind this useful and affordable solar water irrigation system is the efforts of Paul Polak. SunWater uses simple, flat plate mirrors to pull water from a well which in return leads to cost savings up to 80%.

The Artificial Leaf is a creative invention of Daniel Nocera that makes use of sunlight to split water molecules to power its hydrogen fuel cell. The motive behind this invention is to make best use of ample energy that is our sun to power the planet. One artificial leaf placed in quart of water provides 100 watts of energy in a whole day.
Panasonic Solar LED Light
The solar lantern recharges in six hours emits 360 degrees of light, is convenient and practical as a light source as well as a power source in areas without electricity. The built in rechargeable battery is used to store solar energy during the day, provides light at the night. Panasonic Solar LED light may also be used as a power source to small devices, like mobile phones.
Renewable technology had made a significant contribution to climate change mitigation, at the same time as providing affordable and equitable energy access for millions of people.
