Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

Elon Musks Next Disruption Residential Energy Storage

Elon Musks Next Disruption Residential Energy Storage
On top of taking the auto industry by storm, Elon Musk might well be on the road to disrupt the electric power distribution industry, as well, developing a battery storage system for the residential market. Tesla's CEO announced last week that his company is looking to enter the residential energy storage market that is considered to have a huge growth potential. During an earnings conference call, Musk said that Tesla is already working on a home storage battery, that could eventually take utilities out of the picture for some homeowners.

Tesla plans to start production of a stationary battery that would power homes in about six months, as part of the company's commitment to renewable energy and a carbon-free future. Although Musk hasn't shared any details on the design and specifications of the battery, it will probably be a lithium-ion battery pack that will likely be manufactured in the Gigafactory that is under construction in Nevada. The residential energy storage unit will be connected to solar power systems that generate electricity through solar energy, which will be stored in the large battery packs manufactured by Tesla. This way, homeowners will either be able to completely disconnect from the grid or reduce their electric bills substantially.

The batteries for home energy storage project will be conducted in collaboration with Solar City, the company that installs solar energy systems and builds EV charging stations, and is partially owned by Elon Musk. The plan is for Tesla to supply Solar City with battery packs, with Solar City installing them at households, and later on at commercial buildings.

Tesla and Solar City are already working on a similar project together, with Tesla providing batteries to Solar City, which then sells or leases them to homeowners, so that they can generate and store larger amounts of electricity. This helps homeowners cut their electricity costs, but also, eases the strain on the power grid.

Installing large battery packs in residential buildings addresses a couple of big issues associated with solar power systems. For starters, they rely on sunlight to generate electricity, which means that they are not effective during nighttime and when there is no sunlight, forcing consumers to use electricity from the power grid. On the other hand, when the solar power systems generates more electricity than a household can use, the excess electricity is sent back to the grid, putting it under additional strain. With Tesla's batteries, the grid would not have to deal with excess power, as they will have the capacity to store large quantities of electricity, without having to send it back to the grid.

This is reason enough for utilities to start worrying about their future and the possibility of going out of business, given that larger and more efficient batteries, paired with more affordable solar panels might make many consumers get off the grid and start relying exclusively on solar power to meet their energy needs. Even though this possibility is still far from becoming a reality, it seems that Tesla is already starting to cause quite a stir in the electric power distribution industry, which does seem to be ripe for a transformation.
