1. Solar cars/electrically propelled cars
Solar and electric cars are great environmental substitutes that can potentially replace traditional fossil-fuel-powered cars. A solar car utilizes the energy of the sun and an electric car runs on battery power. Both cars can help lessen the use of leads and emission of carbon dioxide and thus reduced pollution.
2. Algae to replace oil
There are many alternative fuel ideas,renewable fuels and alternatives fuels that exist.
It is becoming more important everyday to move from using gasoline in our vehicles to using an alternative fuels programs. You will see this year the Nissan Leaf and Chevy Volt electric cars hit the US market and there will continue to be electric, hydrogen and other alternative fuel ideas that get introduced.
One area that does not usually get a lot of attention is using Algae as renewable fuels. There have been hundreds of millions of dollars invested in using algae as an alternative fuel source. Many top scientists and Venture Capitalists are betting on algae as a replacement to oil.
3. The (Almost) Waterless Washing Machine
This washing machine is called Xeros’s eco-friendly washing machine that saves up to 90% water. It is achieved by using nylon beads that tumble wash clothes using 90% less water as well as less detergent as compared to the usual washing machines.
The technology builds on research out of the U.K.'s University of Leeds and has been applied in a concept washing machine with the help of Cambridge Consultants.
4. Eco night lights
It is called the solar power and energy-efficient LED lamp. This eco-friendly nightlight doesn't use batteries, bulbs or electricity.
The orange one is called the Sun Jars collect solar energy during the day and emits a warm amber glow at night. Containing an energy efficient LED and a rechargeable battery, the Sun Jar will give light for up to 5 hours with each charge.
The blue one is called the Moon Jar is a frosted mason jar with a solar panel and an LED light inside. Put it on your windowsill to soak up the sun rays during the day, and at night the Moon Jar will illuminate your room with a soft cool glow — no cords or electricity required.
5.Biodegradable food packaging
Biodegradable food packing are made from a renewable resource- sugarcane. After the cane juice is extracted from the plant, the stalk is ground and made into paper pulp. The paper pulp is then made into a variety of products, such as compostable plates, biodegradable bowls and eco-food containers. These products are heat stable, grease-resistance and microwave safe. Better yet, it is usually less expensive.
