However, nuclear disasters have raised concerns over the safety of nuclear power, and the capital cost of nuclear plants is very high. Along with the invention of long-distance power transmissionthe coordination of power plants began to form. Plants need water as part of their food supply. Natural Power Generation

Natural Power Generation -

Below are a few examples: Electrical energy can be generated by the movement of water in different ways. Hydro-Electric Dams hold water above its natural level creating a head pressure needed to power generators. Turbines have been designed to take advantage of the Mississippi River and the Gulf Stream.

Ocean Thermal gradients are the temperature difference between surface and deep waters. In some parts of the world, heat engines can be powered this way. Tidal power can harness ocean movement resulting from gravitational forces of the moon. Dams can trap water to be released through turbines.

Turbines that take advantage of water movement in both directions are more efficient. Cooling with water is possible by exposing it to the clear night sky where heat is given up by radiation. Ponds on flat roofs are used in this manner. Heat can also be lost through evaporation.

Water sprayed on roofs is beneficial even in humid areas, but more efficient in arid areas. Caution should be used in areas of scarce water or drainage problems.

Thermal Inertia is the stabilizing of temperatures by a large body of water. Coastal, riverfront, and lakefront cities are known for their milder climates and refreshing breezes. The wind movement is generated by the temperature difference from water to land.

The temperature difference between day and night is much greater on land than over water. That is one reason why Alexandria is warmer in the summer and colder in the winter than New Orleans. Thermal Storage by water is four times the capacity of concrete, brick or gravel.

Each gallon of water can hold Btus of thermal energy. The heat in water is fairly evenly distributed by convection. Cleaning water takes place through its movement. This movement causes it to drop the heavier impurities and gives it greater exposure to the sun and air.

Algae and micro-organisms which live in the water also help to clean it. Plants need water as part of their food supply. Water can be retained in cisterns or ponds for landscaping and greenhouse use.

Conservation of water is important because it takes more and more energy to clean water and move it to your building. Recycling of a fixed supply of water on, in, and around the Earth is a natural system. It can change states from solid to liquid to gas.

Gray water from your building can be reused before disposal. Earth Earth is an almost spherical body approximately 4, miles in radius. The center is occupied by a hot core 2, miles in radius which is surrounded by the 1, mile thick mantle. The outer crust is only 5 to 25 miles thick.

It is within a few inches above and below the ground surface that earth, air, and water mix in the presence of sunlight. Here phenomena or processes of chemistry, osmosis, transpiration, decay, transmutation, and regeneration take place.

We are absolutely dependent upon the workings within this fragile matrix. Fossil Fuels are formed and contained in the earth. They are a valuable energy source which is renewable only on an extremely protracted time scale measured in millions of years.

Cooling and Heating can be used by the thermal lag between surface temperatures and those below ground. At a depth of 15 feet below ground, the temperatures will be about three months behind the surface temperatures. In Lafayette, the average yearly deep ground temperature is around 68°F in the summer to 71°F in the winter.

Insulation value can be given to the earth by tempering heat gains or losses through roofs, walls, and floors. Water pipes in the ground below the frost line are protected from freezing temperatures.

Earth forms can be designed to protect buildings from wind and other harsh weather conditions, or they can be formed to channel air into the building. Geothermal energy is provided by subterranean movement of water in contact with the intense heat produced at the Earth's core.

This source can provide steam and hot water. Geopressure can be found deep in the ground. This pressure can move turbines to produce mechanical or electrical energy. Purification of water occurs as it percolates down through the soil where impurities are deposited. This process is aided by aerobic and anaerobic bacteria in the soil that over time reduce most waste to a harmless state.

Building Materials can be obtained from the Earth at the site without or with less of the expense of manufacturing and transporting them. Stabilized earth, adobe blocks, rammed earth, earth floors, sod roofs, and mud surfacing are examples of on site, low cost building material potentials.

Vegetation It is important to understand the value of plant life on Earth. It is interesting that words plant and planet are so much alike. Photosynthesis takes place in the chlorophyll cells of green plants -- consuming carbon dioxide, producing carbohydrates, and freeing oxygen.

This relationship of sun and plants that created the biosphere around the Earth allows man and animals to survive. Biomass is the plant and animal material produced by photochemical reaction.

Fire, Heat and Light are the release of the sun's energy used in creating the wood when wood is burned. Free oxygen is added back by the chemical process during combustion.

Chemically, a wood fire is the reversal of nature's growth process but at a much greater speed. Care must be taken to provide complete combustion, otherwise pollutants will be released into the air. Methane is a colorless, odorless, flammable gas which is formed by the decomposition of organic waste products of living organisms on Earth.

Methane, the main component of natural gas, can be used as a heating fuel and for illumination. In addition, its by-product can be used as fertilizer. Alcohol can be obtained by a fermentation process producing Ethanol or by a distillation process creating Methanol.

Insulation in the form of cellulose is a wood product made from recycled newspapers. Vegetation used as a wind break helps the insulation properties of a building. Purification of the air is probably the greatest asset of plant life along with food, which nourishes and sustains life. Winn, Natural Louisiana Architecture, Designing for Comfort and Energy, Dept.

of Natural Resources, Baton Rouge, Louisiana, ACTIVITY 1: Directions: The student should read the material and locate on the letter matrix, the energy sources that are in bold italics. Define nuclear energy. Nationally and internationally , large hydroelectric plants—or mega-dams —are often considered to be nonrenewable energy.

Mega-dams divert and reduce natural flows, restricting access for animal and human populations that rely on those rivers. Small hydroelectric plants an installed capacity below about 40 megawatts , carefully managed, do not tend to cause as much environmental damage, as they divert only a fraction of the flow.

Biomass is organic material that comes from plants and animals, and includes crops, waste wood, and trees.

When biomass is burned, the chemical energy is released as heat and can generate electricity with a steam turbine. Biomass is often mistakenly described as a clean, renewable fuel and a greener alternative to coal and other fossil fuels for producing electricity.

However, recent science shows that many forms of biomass—especially from forests—produce higher carbon emissions than fossil fuels. There are also negative consequences for biodiversity. Still, some forms of biomass energy could serve as a low-carbon option under the right circumstances. For example, sawdust and chips from sawmills that would otherwise quickly decompose and release carbon can be a low-carbon energy source.

Drilling deep wells brings very hot underground water to the surface as a hydrothermal resource, which is then pumped through a turbine to create electricity. Geothermal plants typically have low emissions if they pump the steam and water they use back into the reservoir. There are ways to create geothermal plants where there are not underground reservoirs, but there are concerns that they may increase the risk of an earthquake in areas already considered geological hot spots.

Some tidal energy approaches may harm wildlife, such as tidal barrages, which work much like dams and are located in an ocean bay or lagoon. Passive solar homes are designed to welcome in the sun through south-facing windows and then retain the warmth through concrete, bricks, tiles, and other materials that store heat.

Some solar-powered homes generate more than enough electricity, allowing the homeowner to sell excess power back to the grid. Batteries are also an economically attractive way to store excess solar energy so that it can be used at night.

Scientists are hard at work on new advances that blend form and function, such as solar windows and roof shingles. Geothermal technology is a new take on a recognizable process—the coils at the back of your fridge are a mini heat pump, removing heat from the interior to keep foods fresh and cool.

In a home, geothermal or geoexchange pumps use the constant temperature of the earth a few feet below the surface to cool homes in summer and warm houses in winter—and even to heat water.

Geothermal systems can be initially expensive to install but typically pay off within 5 to 10 years. They are also quieter, have fewer maintenance issues, and last longer than traditional air conditioners. A backyard wind farm? Boats, ranchers, and even cell phone companies use small wind turbines regularly.

Dealers now help site, install, and maintain wind turbines for homeowners, too—although some DIY enthusiasts are installing turbines themselves. Depending on your electricity needs, wind speeds, and zoning rules in your area, a wind turbine may reduce your reliance on the electrical grid. Wind- and solar-powered homes can either stand alone or get connected to the larger electrical grid, as supplied by their power provider.

Electric utilities in most states allow homeowners to only pay the difference between the grid-supplied electricity consumed and what they have produced—a process called net metering.

If you make more electricity than you use, your provider may pay you the retail price for that power. Advocating for renewables, or using them in your home, can accelerate the transition toward a clean energy future.

Contact your power company to ask if it offers that choice. This story was originally published on June 15, , and has been updated with new information and links.

Types of Renewable Energy Sources. Solar Energy Humans have been harnessing solar energy for thousands of years—to grow crops, stay warm, and dry foods.

Other Alternative Energy Sources. Hydroelectric power Hydropower is the largest renewable energy source for electricity in the United States, though wind energy is soon expected to take over the lead.

It will increase countries' energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainabilityreduce pollution, lower the costs of mitigating climate changeand keep fossil fuel prices lower than otherwise.

These advantages are global. Hence the additional costs of the incentives for early deployment should be considered learning investments; they must be wisely spent and need to be widely shared". Solar energy can be harnessed anywhere that receives sunlight; however, the amount of solar energy that can be harnessed for electricity generation is influenced by weather conditionsgeographic location and time of day.

According to chapter 6 of the IPCC climate mitigation report, the global potential of direct solar energy far exceeds that of any other renewable energy resource. It is well beyond the total amount of energy needed in order to support mitigation over the current century.

There are, however, environmental implications of scaling up solar energy. In particular, the demand for raw materials such as aluminum poses concerns over the carbon footprint that will result from harvesting raw materials needed to implement solar energy.

Photovoltaics PV is rapidly-growing with global capacity increasing from GW at the end of to GW in PV uses solar cells assembled into solar panels to convert sunlight into electricity.

PV systems range from small, residential and commercial rooftop or building integrated installations, to large utility-scale photovoltaic power station. The predominant PV technology is crystalline siliconwhile thin-film solar cell technology accounts for about 10 percent of global photovoltaic deployment.

In recent years, PV technology has improved its electricity generating efficiencyreduced the installation cost per watt as well as its energy payback timeand reached grid parity.

Building-integrated photovoltaics or "onsite" PV systems use existing land and structures and generate power close to where it is consumed. Photovoltaics grew fastest in China between and adding GW, more than all advanced economies combined.

Solar PV's installed power capacity is poised to surpass that of coal bybecoming the largest in the world. As the cost of solar electricity has fallen, the number of grid-connected solar PV systems has grown into the millions and gigawatt-scale solar power stations are being built.

Many solar photovoltaic power stations have been built, mainly in Europe, China and the United States. Many of these plants are integrated with agriculture and some use tracking systems that follow the sun's daily path across the sky to generate more electricity than fixed-mounted systems.

Solar thermal energy STE is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in industryand in the residential and commercial sectors.

Solar thermal collectors are classified by the United States Energy Information Administration as low- medium- or high-temperature collectors. Low-temperature collectors are generally unglazed and used to heat swimming pools or to heat ventilation air.

Medium-temperature collectors are also usually flat plates but are used for heating water or air for residential and commercial use. Two categories include Concentrated Solar Thermal CST for fulfilling heat requirements in industries, and Concentrated Solar Power CSP when the heat collected is used for electric power generation.

CST and CSP are not replaceable in terms of application. Air flow can be used to run wind turbines. Modern utility-scale wind turbines range from around kW to 9 MW of rated power. The power available from the wind is a function of the cube of the wind speed, so as wind speed increases, power output increases up to the maximum output for the particular turbine.

Wind energy was the leading source of new capacity in Europe, the US and Canada, and the second largest in China. Globally, the long-term technical potential of wind energy is believed to be five times total current global energy production, or 40 times current electricity demand, assuming all practical barriers needed were overcome.

This would require wind turbines to be installed over large areas, particularly in areas of higher wind resources, such as offshore, and likely also industrial use of new types of VAWT turbines in addition to the horizontal axis units currently in use. Since water is about times denser than aireven a slow flowing stream of water, or moderate sea swellcan yield considerable amounts of energy.

Hydropower is produced in countries, with the Asia-Pacific region generating 32 percent of global hydropower in Much hydropower is flexible, thus complementing wind and solar. Ocean thermal energy conversionwhich uses the temperature difference between cooler deep and warmer surface waters, currently has no economic feasibility.

Inthe world renewable hydropower capacity was 1, GW. Because dispatchable power is more valuable than VRE [] [] countries with large hydroelectric developments such as Canada and Norway are spending billions to expand their grids to trade with neighboring countries having limited hydro.

Biomass is biological material derived from living, or recently living organisms. It commonly refers to plants or plant-derived materials.

As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel in solid, liquid or gaseous form. Conversion of biomass to biofuel can be achieved by different methods which are broadly classified into: thermalchemicaland biochemical methods.

Wood was the largest biomass energy source as of ; [] examples include forest residues — such as dead trees, branches and tree stumpsyard clippings, wood chips and even municipal solid waste. Industrial biomass can be grown from numerous types of plants, including miscanthusswitchgrasshempcornpoplarwillowsorghumsugarcane, bamboo[] and a variety of tree species, ranging from eucalyptus to oil palm palm oil.

Plant energy is produced by crops specifically grown for use as fuel that offer high biomass output per hectare with low input energy. Plant biomass can also be degraded from cellulose to glucose through a series of chemical treatments, and the resulting sugar can then be used as a first-generation biofuel.

Biomass can be converted to other usable forms of energy such as methane gas [] or transportation fuels such as ethanol and biodiesel. Rotting garbage, and agricultural and human waste, all release methane gas — also called landfill gas or biogas.

Crops, such as corn and sugarcane, can be fermented to produce the transportation fuel, ethanol. Biodiesel, another transportation fuel, can be produced from left-over food products such as vegetable oils and animal fats. The biomass used for electricity generation varies by region.

Forest by-products, such as wood residues, are common in the United States. Agricultural waste is common in Mauritius sugar cane residue and Southeast Asia rice husks.

Pollutants such as sulphurous oxides SO xnitrous oxides NO xand particulate matter PM are produced from the combustion of biomass. With regards to traditional use of biomass for heating and cookingthe World Health Organization estimates that 3. Bioenergy global capacity in was GW.

Biofuels avoided 4. Biofuels include a wide range of fuels which are derived from biomass. The term covers solidliquidand gaseous fuels. Gaseous biofuels include biogaslandfill gas and synthetic gas. Bioethanol is an alcohol made by fermenting the sugar components of plant materials and it is made mostly from sugar and starch crops.

These include maize, sugarcane and, more recently, sweet sorghum. The latter crop is particularly suitable for growing in dryland conditions, and is being investigated by International Crops Research Institute for the Semi-Arid Tropics for its potential to provide fuel, along with food and animal feed, in arid parts of Asia and Africa.

With advanced technology being developed, cellulosic biomass, such as trees and grasses, are also used as feedstocks for ethanol production. Ethanol can be used as a fuel for vehicles in its pure form, but it is usually used as a gasoline additive to increase octane and improve vehicle emissions.

Bioethanol is widely used in the United States and in Brazil. The energy costs for producing bio-ethanol are almost equal to, the energy yields from bio-ethanol. However, according to the European Environment Agencybiofuels do not address global warming concerns.

It can be used as a fuel for vehicles in its pure form, or more commonly as a diesel additive to reduce levels of particulates, carbon monoxide, and hydrocarbons from diesel-powered vehicles.

Archived from the original on 26 December Once electricity leaves a generating facility, the voltage is increased, or "stepped up," by a transformer typical ranges of kV to 1, kV to minimize the power losses over long distances. Renewable energy, often referred to as clean energy , comes from natural sources or processes that are constantly replenished. Over the past decade, wind power has grown to become the third-largest source of electricity generated in the state.

Natural gas has more than doubled its share of electricity generation in Massachusetts over the past two decades. The amount of power created from solar energy has increased sharply in the state since This year, the state toughened its mandate for utilities to sell electricity from renewable sources, raising the requirement to 3 5 percent of total sales by The new legislation also encourages offshore wind development.

Massachusetts consumes more electricity than it produces in-state and gets the remainder from nearby states through the regional grid. Coal remained the top source of electricity produced in Michigan last year, but its generation share declined from a little over 60 percent in to just under 40 percent in During the same period, natural gas nearly doubled its generation share.

In , Michigan required utilities and other electricity providers to get at least 10 percent of the power they sell to customer from renewable sources by That goal was met and subsequently expanded to 15 percent by Coal has been the top source of electricity generated in Minnesota for the past two decades.

The state requires utilities to gradually sell an increasing amount of electricity from renewable sources, with a requirement of 25 percent of total sales by Natural gas powered more than three-quarters of the electricity generated in Mississippi last year.

Coal provided 36 percent of the electricity produced in-state in , but just 8 percent in Coal provided the vast majority of power generated in the state between and , declining only slightly during that time as older coal-fired plants went offline or switched to burning natural gas.

Missouri will require utilities to get at least 15 percent of the electricity they sell from renewable sources by , including a small amount from solar power. Coal has been the top source of electricity produced in Montana for nearly two decades but its generation share declined from 70 percent in to just under 50 percent last year.

Montanans only use about half of the electricity produced in the state, according to the E. The state sends the rest to its Western neighbors. Coal has been the top source of electricity produced in Nebraska for nearly two decades, but its generation share declined slightly between and Wind has been increasing its share of total generation over the past decade, accounting for 15 percent of the electricity produced in the state last year.

Nebraska has the potential for substantially more wind power, according to the E. More Nevada coal generators have shuttered since then because of competition from cheap natural gas and state laws that require renewable energy development.

Until recently, Nevada required that 25 percent of the electricity sold by utilities in the state come from renewable sources by In November, Nevadans voted to increase that requirement to 50 percent by The bulk of electricity generated in New Hampshire comes from the Seabrook nuclear power plant, the largest reactor in New England.

Natural gas has provided about a fifth of the power produced in the state since the early s, when two new generating stations began operating. The state is requiring utilities to get 25 percent of the electricity they sell to customers from renewable resources by The top two sources of renewable energy in the state are biomass, or energy that comes from burning wood and other organic matter, and hydroelectric power.

Exports are not included in the chart above. Nuclear power was the top source of electricity generated in New Jersey until recently, when it was edged out by natural gas.

This year, New Jersey increased its renewable energy standard to require that 21 percent of the electricity sold in the state come from renewable sources by , with that requirement increasing to 35 percent by and to 50 percent by In an effort to further reduce carbon emissions, the state also passed legislation to prop up its nuclear plants, which currently provide the largest portion of zero-emissions energy.

The state gets some of the power it consumes through the Mid-Atlantic regional grid. Natural gas, wind and solar accounted for a little less than half of the electricity produced in New Mexico last year, up from just 15 percent two decades earlier.

The state will require utilities to get 20 percent of the electricity they sell from renewable energy by New Mexico is also looking to increase generation from zero-carbon sources because it sends a significant amount power to California, a state with some of the strictest renewable energy policies in the country.

Natural gas and nuclear power have supplied the majority of electricity generated in New York for nearly two decades and their share has expanded as coal use in the state has declined. The state will require utilities to get 50 percent of the power they sell to consumers from renewable sources by , an ambitious goal, and aims to substantially reduce greenhouse gas emissions.

New York tends to consume more energy than it creates and imports some electricity from neighboring states and Canada. Electricity imports are not included in the chart above. Natural gas generation increased after the national fracking boom of the late s and became the second-largest source of electricity generation in the state in North Carolina is currently the only Southern state with significant solar generation.

North Carolina has also set a requirement that utilities get As in many Great Plains states, wind energy has taken off in North Dakota over the past decade. Last year, wind powered more than a quarter of the electricity produced in the state, up from less than 2 percent a decade earlier.

In , the North Dakota Legislature set a voluntary goal for utilities: to get 10 percent of the electricity sold to consumers from renewable or recycled energy by That goal was met and even surpassed, according to utility analysts. North Dakota produces more electricity than is consumed in the state and about half is sent to its neighbors.

Exports are not charted above. The state wants to expand that, however. It will require utilities to get at least But in , wind surpassed coal as the second-largest source of electricity produced in the state. Last year, the state was second only to Texas in total electricity generation from wind.

In , Oklahoma requ ired that 15 percent of its generation capacity comes from renewable sources by It also designated natural gas as its preferred choice for new fossil fuel projects.

The state had exceeded the renewable target by Most of the electricity produced in Oregon in any given year comes from hydropower but the share produced from water fluctuates with precipitation. Power from natural gas typically increases during drought years, and decreases in years with ample hydroelectricity.

Over the past decade, wind power has grown to become the third-largest source of electricity generated in the state. In an effort to encourage more non-hydroelectric renewable energy, Oregon will require its largest utilities to get 50 percent of the electricity they sell from new renewable energy sources by The program covers projects introduced or upgraded since , a cutoff that would exclude older hydropower.

Coal powered the bulk of electricity produced in Pennsylvania through , when it fell below nuclear for the first time. Last year, nuclear power was the top source of electricity generated in Pennsylvania. Pro-nuclear groups, saying the loss of this emissions-free electricity is bad news for climate change, have sought state subsidies for nuclear energy.

Data are for net electricity generation. Most small-scale PV systems are at or near the location where the electricity is consumed and many are net metered systems.

Smaller PV systems are usually installed on building rooftops. Most pumped storage systems use fossil fuels or nuclear energy for pumping water to the storage component of the system.
