As a category, renewable energy encompasses a broad range of energy technologies and fuels, ranging from photovoltaic solar cells to the burning of animal dung for fuel in many poor regions of the world. Major sources of renewable energy –– in the rough order of the amount of energy they contribute globally –– include hydroelectric power, wood used for heating, cooking, and electrical generation, bioenergy produced from agricultural crops and waste, wind energy, concentrated solar power generated with mirrors and steam turbines, photovoltaic solar cells, geothermal energy, and tidal energy.

Sources of “renewable” energy are finite but inexhaustible, meaning that there is a physical limit to how much energy might be produced from any given renewable energy technology, but the maximum utilization of that technology in the present does not diminish our ability to utilize it in the future. There is, for instance, a theoretical limit to the amount of solar radiation that might be harnessed for energy production today, but fully utilizing all of the solar radiation hitting the earth today does not diminish our ability to fully utilize that radiation tomorrow. Similarly, burning wood for fuel this year does not diminish the long term capacity to burn wood for fuel so long as the amount of wood harvested for fuel annually does not exceed the rate at which forests grow.

That depends on what you mean. Until a few hundred years ago, we powered the entire world almost entirely with renewable forms of energy, mostly by burning wood for fuel, using animal fats like whale oil for lighting, and using animal labor for motive power.1 But 100 years ago, the world had vastly fewer people, virtually all of whom were significantly poorer than the average person today.2

So the question is whether we can power today’s world, or, more accurately, the world in 2040 or 2050, with renewable energy. The world in 2050, with a population exceeding 9 billion people and a greater proportion having achieved modern living standards, will almost certainly require at least twice as much energy as the world today, and more than 50 times more energy than was required to power the pre-industrial world when we last depended primarily on renewable energy sources.3

Some analyses suggest that it is theoretically possible to power today’s world with renewable energy, but these analyses uniformly assume drastic reductions in global energy consumption.4 Such projections also assume significant breakthroughs in the scalability and reliability of renewable energy technologies while typically failing to account for the costs or the amount of land needed to scale up to levels consistent with meeting expected future energy demand.

Currently, the world gets about 9 percent of its primary energy from renewables sources. That compares with close to 100 percent in 1800, about 60 percent in 1900, and 38 percent in 1950. Of today’s 9 percent, approximately 74 percent is produced by hydroelectric dams, 13 percent is produced by bioenergy, 10 percent is produced by wind turbines and 2 percent from solar power. Some nations get most of their electricity from renewables; of these, most get the vast majority of that energy from hydropower, notably Brazil, which gets 75 percent of its electricity from hydropower, Norway, which gets 96 percent, and Sweden and Switzerland, which each get about 50 percent.5

Cleaner and Greener Environment: Renewable energy usage will greatly reduce the amount of greenhouse gas emissions that come with the traditional energy sources. The environmental impact of renewable energy sources is close to none. Why not invest in living on a better planet?

Infinite Energy Source: With renewable energy you can be sure that you are providing the coming generations not only with a better environment but also with an energy that will hardly ever run out. Besides, as noted above, it keeps getting cheaper which means that your grandchildren will have a chance of paying close to nothing for the electricity they use.

Economy: Renewable energy sources function on certain facilities (solar panels, wind turbines, etc.) that require well-thought workmanship. This means that the higher the demand for renewable energy sources, the more new jobs will be created for people who create these facilities and install them. Besides, the economy also grows as the US sells renewable energy systems overseas as well.  

Fight against Global Warming: As more and more people start using renewable energy, the biggest threat of our era - global warming might start its retreat. With the help of clean energy you will be able to contribute to climate change in a positive way. .

Although not applicable in some countries, where permitted, we can introduce Net metering. This is an electric billing tool where a solar power owner gets credited for the electricity they add to their local grid. Most times, the energy added to the grid is usually excess power generated by the solar system which is not being used by the owner. Now, if we get your power system net-metered, the meter will retrace backward to credit you against the electricity you consume at night or when the energy consumed exceeds that generated by the solar plant

Lower Energy Bills: This is probably the main reason why your business should go green. Instead of paying thousands of dollars for your monthly electricity bills, you can pay much less if you convert to a renewable energy source.

Tax Credits: Your company can get tax incentives from the local government as a reward for your green initiative. Besides, you might also be able to cover at least 30% of your renewable energy system installation with the help of these incentives.

Improved Reputation and More Customers: People will highly appreciate your step toward reducing your carbon footprint and going green. It will make them feel that you care about them and the environment which will highly increase the possibility of many customers choosing your services over others. This will earn you a good reputation and possibly increase your sales. Besides, conversion to a renewable energy source will have your employees stay with you longer and be loyal to the goals of your company.

Healthier Environment for You and Your Employees: And last but not least, having a renewable energy source at your company will make it a cleaner place for long and loaded working days. Reducing your carbon footprint, you will have a positive effect not only over the whole environment but also on a smaller scale, on the office you are working at. Don’t harm the health of your employees by sticking to the traditional energy sources which are going to run out sooner or later.

Net metering is the system that utilities use to credit solar energy system owners for the electricity produced by their solar panels. With net metering, you only pay for the electricity that you use beyond what your solar panels can generate. Net metering policies differ from state to state – from Massachusetts to California to Hawaii – so make sure to do your homework ahead of time.

Solar panels absorb the sun's energy throughout the day and convert it into direct current (DC) electricity. Most homes and businesses run on alternating current (AC) electricity, so the DC electricity is then passed through an inverter to convert it to usable AC electricity. At that point, you either use the electricity in your house or send it back to the electric grid.

Solar panels are built and installed to endure harsh and unpredictable weather conditions, even in situations with lots of snow, rain, and wind. Only in the most extreme cases like places with lots of hurricanes, solar panels may not hold up very well. But that could also be said for the condition of the home as a whole.

For most places with strong winds or harsh weather conditions, counties and cities will require a specific way to design and install the solar panels to accommodate for different wind uplift speeds. These speeds can range anywhere from 3-5 seconds at 130 MPH in areas like Upload, California and Rancho Cucamonga, California. CAD designers and Engineers will make be sure to take these factors into account as they do the load calculations for your home.

Solar panels are typically guaranteed to last for 25 years but can last for more than 40 years. Even after 25 years, your solar panels would still produce 75-80% of its original performance. Not only will your solar panels last for decades, but it will also continue to perform highly.
