Due to a number of major factors, including the state of the economy, the climate crises and the general higher visibility of environmental issues, renewable energy has become a significant and high profile subject. Now, more than at any time in history, there is a growing awareness of our impact on the planet and consequently a growing movement toward environmental responsibility through the use of renewable energy.

The fundamental shift toward using renewable energy is not just motivated by those who are environmentally conscious and who want to do their part to stabilize the climate. Renewable energy is also attractive to the countless people out there who are interested in saving money on heating and cooling bills by using alternative energy sources. Regardless of the motivation, the result is the same; unprecedented numbers of average people are looking into all types of renewable energy in order to save money on household energy bills. Many have numerous questions about renewable energy. Here are some renewable energy FAQs:

What is renewable energy?

Renewable energy is generally defined as energy that is unlimited in quantity and which renews or regenerates itself without any input from humans.

What are the different types of renewable energy?

Solar power: one of the most popular and reliable forms of renewable energy available, today, solar power is collected by solar panels that have numerous solar cells that store the sun’s energy and convert it into electricity, just like a traditional battery. Solar panels are usually installed on the roofs of structures and are linked together and then tied into the house’s electrical wiring system. Many people find that having a solar power system saves them dramatic amounts of money in heating and cooling bills and some people are even able to disconnect entirely from the electric company and live off the grid on solar power.

Wind power: wind power comes from wind generators that capture the kinetic energy from the wind and translate it into electricity. This is essentially accomplished with propellers mounted on towers. As the wind turns the propellers, electricity is generated. Many electrical cooperatives have built large farms of massive wind generators, but a scaled down version is available for residential use.

Hydrogen furnace: while somewhat different and much more complex than solar or wind power, hydrogen furnaces are just beginning to become proven and reliable technology to create unlimited sources of energy. Essentially, the hydrogen furnace produces energy from waste material by separating the hydrogen molecules. Hydrogen furnaces have posed massive engineering problems for years, but recently there have been breakthroughs that have allowed this technology to become viable.



Can one save money by using renewable energy?

If done correctly, one could save thousands of dollars per year in electricity costs by using renewable energy technology such as solar or wind power. In many places, solar panels can provide the majority if not all of the electricity necessary to power a household every month. The cost of installing a renewable energy system is often recaptured in savings in the first year.
