Renewable energy, clean or “green” energy, sustainability, and corporate responsibility have become primary business concerns, with a measurable impact on consumer and investor interest in all types of businesses.

Solar is the 100% renewable energy, and it makes our environment pollution free and reduces risks of Global warming, Smog and Acid rain. Today, most homes and business industries are using Solar Panel for generating electricity.

renewable energy sources

The original concept for the Renewable Energy Initiative came during February 2004 from Ernie Hodgson, a former President of ASU Sustainable Energy Society. His idea was based on a similar concept that was initiated at UNC Chapel Hill. With the help of other students interested in pursuing the initiative, he brought the idea before the Student Government Association which then approved the senate bill to present a referendum to the student body. Miriam Makhyoun and SGA Senator Justin Pittman aided Ernie Hodgson, Cole McVey and Jeff Lauckhart in writing the enabling act for the referendum

Turning to the use of abundant renewable energy sources other than large-scale hydro for electricity, there are challenges in harnessing them. Apart from solar photovoltaic (PV) systems which produce electricity directly, the question is how to make them turn dynamos to generate the electricity. If it is heated that is harnessed, this is via a steam generating system.

There are places around the globe where renewable energy is on par or cheaper than conventional energy production and this trend will only continue. It is more about local economics than a battle of technologies. Subsidies will speed solar adaption, but they are no longer a necessity. So, what you say is true, but the adjectives of "much more" and "heavily" are false.

Most developing countries have abundant renewable energy resources, including solar energy, wind power, geothermal energy, and biomass, as well as the ability to manufacture the relatively labor-intensive systems that harness these.

By developing such energy sources, developing countries can reduce their dependence on oil and natural gas, creating energy portfolios that are less vulnerable to price rises. In many circumstances, these investments can be less expensive than fossil fuel systems. Ultimately, the transition to 100% clean, renewable energy is all about you.

At least half of the 25 percent requirement must be generated from renewable energy sources, including wind, hydro, geothermal and at least 0.5 percent from solar energy. The law also requires utilities to implement energy efficiency reduction programs to cut demand by 22 percent by 2025, compared with 2009 levels.

Hydropower Energy

How do we define hydropower? Hydropower energy deals with the use of hydraulic power or water power using the force of moving water for purposes of generating commercial electric power use of irrigation and farming, and other uses. This is considered an alternative source of energy, alongside solar power and wind energy.

This is a find choice for anyone who like to be involved with the field of renewable energy. There are some advanced training programs that will give the participants some good insight into all of the latest trends and techniques that are part of this field.

The training is well designed to increase the overall skills and knowledge of hydropower developments and also the training will cover any recommendations that are made in the world commission of dams.

The main thing when people use the hydropower energy is because for the environmental friendly power. There is no need to worry about carbon dioxide. The hydropower system is climate friendly and carbon free. The earth will be safe when you use since the risk for pollution is lowered.

Compared to other states in US, the northwest area only has a half carbon emission rate. Another source for energy with low emission is explained in solar energy facts. The electricity for the Washington PUDs is supplied for more than 82 percent from the hydropower energy. It the northwest area, it occupies 61 percent of all energy.

More than 20 percent of all electric generations have been created from the hydropower. Many countries now concern with the hydropower energy because it is renewable and simple.

A new study by Water in the West, a research center at Stanford University, lays this all out in a report called, "Water and Energy Nexus: A Literature Review." The report finds robust opportunities for reductions in greenhouse gas emissions, as well as for the conservation of scarce water resources.

A comprehensive survey of publications by academic, government and nonprofit sectors over the last 23 years, it also identifies substantial money- and energy-savings opportunities for water and wastewater managers.

Falling or flowing water from a big river has much energy. We can harness this by forcing the water through a pipe called a penstock. As the water flows through the pipe it turns the blades of a turbine that spins an electric generator. As long as the water is flowing, the generator will be able to provide electricity.

Hydropower is using water to power machinery or make electricity. Water constantly moves through a vast global cycle, evaporating from lakes and oceans, forming clouds, precipitating as rain or snow, then flowing back down to the ocean. The energy of this water cycle, which is driven by the sun, can be tapped to produce electricity or for mechanical tasks like grinding grain.

Hydropower uses a fuel—water—that is not reduced or used up in the process. Because the water cycle is an endless, constantly recharging system, hydropower is considered a renewable energy.

If a region is blessed with abundant water supply in the form of free-flowing rivers, hydropower is undoubtedly the best bet among the available alternative energy sources. Basically, hydropower or hydroelectricity is electricity produced by harnessing moving water by constructing a dam on the river.

Hydropower Energy

The water from this dam is released in a controlled manner to rotate the turbines, and this rotation of turbines generates electricity. If you take into consideration the numerous pros of hydroelectric power that are put forth by its advocates, it looks more than promising. The critics though don't seem to be impressed by it. In fact, they seem to be more worried about its drawbacks.

When it rains in hills and mountains, the water becomes streams and rivers that run down to the ocean. The moving or falling water can be used to do work. Energy, you'll remember is the ability to do work. So moving water, which has kinetic energy, can be used to make electricity.

Hydroelectric power uses the kinetic energy of moving water to make electricity. Dams can be built to stop the flow of the river. Water behind a dam often forms a reservoir As the picture of Shasta Dam in Northern California pictured on the right. Dams are also built across larger rivers, but no reservoir is made. The river is simply sent through a hydroelectric power plant or powerhouse.

The extent of this relationship, and the scale of it, pumping water over mountains in some cases is rarely seriously considered outside of the wonky water-energy nexus circle. But with the demand for both growing while supplies shrink or rise in the cost, a reckoning with these two trends is as foreseeable as the reckoning of climate change.

In fact, it is exacerbated by climate change, which leads to reduced precipitation and hotter temperatures in many places, elevating demands for water and energy.

When the demand for electricity is low, a pumped storage facility stores energy by pumping water from a lower reservoir to an upper reservoir. During periods of high electrical demand, the water is released back to the lower reservoir to generate electricity.
