Renewable Energy

The consequences of using non-renewable energy resources include environmental degradation such as air and water pollution, habitat destruction, and contribution to climate change through the release of greenhouse gases. Non-renewable resources are finite and will eventually run out, leading to energy scarcity and economic instability. Additionally, the extraction and transportation of non-renewable resources can have detrimental effects on local communities and ecosystems.

Renewable energy sources such as solar and wind power help reduce greenhouse gas emissions and combat climate change. They are also sustainable and can help diversify our energy sources, making our energy systems more resilient and less reliant on fossil fuels. Additionally, renewable energy can help create jobs and stimulate economic growth in the clean energy sector.

the sun has solar energy so that is one way it is started.

The renewable energy resources in the Philippines include solar, wind, hydroelectric, geothermal, and biomass energy. These sources are abundant in the country and have the potential to help reduce dependence on fossil fuels and lower greenhouse gas emissions. The Philippines has been actively investing in these renewable energy sources to promote sustainability and energy security.

Renewable energy resources refer to sources of energy that can be naturally replenished, such as sunlight, wind, and biomass. While energy cannot be created or destroyed according to the law of conservation of energy, renewable energy resources can be harnessed and converted into usable forms of energy without depleting the source. This distinguishes them from non-renewable energy sources like fossil fuels, which are finite and, once used, cannot be easily replaced within a human lifetime.

The sun's energy drives the Earth's weather patterns, creating temperature differences in the atmosphere that cause air to move. This movement of air is what we experience as wind. So, the sun's energy is indirectly responsible for the generation of wind.

A useful definition of a renewable resource is one "that can be replenished naturally with the passage of time." Typical examples of renewable sources of energy include solar (thermal & photovoltaic), wind (turbines), water (dams, tidal, wave), geothermal, and biomass.

There are a number of caveats that should be mentioned here however, such as the fact that at long enough time scales all sources of energy are ultimately finite. For example, the hydrogen that fuels the Sun's conversion of energy into light which yields photosynthetic biomass and that drives Earth's atmospheric wind pressure systems along with its hydrological cycle is consumed irreversibly. Geothermal energy arises from the natural radioactive decay of unstable elements deep in the Earth's interior and such radioactive decay is also finite in nature.

In addition technologies needed to harness these renewable forms of energy require material inputs which are not themselves "renewable". For example, both multi-junction photovoltaic solar cells and wind turbine-generator magnets require rare-earth elements.

Given these qualifications there is no reason to exclude nuclear fission from renewable energy mix. After all both thorium and uranium are a lot more common than rare-earth elements such as indium, neodymium, or praseodymium. Furthermore it is estimated that the oceans of the world contain dissolved within it some 4.5 billion tons of uranium; and its rate of consumption in fast-spectrum breeder reactors would be constantly renewed by additional deposition from rivers and streams.

An example of producing electricity from gravity is the water wheel. Where the force of gravity acting upon the water filled buckets of the wheel rotate it and drive a generator. Or the gravity driven water of a hydroelectric dam which turns turbine blades. This is based on Archimedes principle.

However this technology is still in the initial stages and patent is also declined.

There is another technology based on Newton's Law, this technology is patented (Indian Patent) and several prototypes are made. PILOT is successfully conducted with 20 KWp Model and they are ready to roll out 1 MW Engine. The name of the Engine is "RC Gravity Engine" and they launched a awareness campaign in the name of "The Green Ushers"

It is renewable because you can always raise an object or raise yourself and gain gravitational potential energy. You cannot run out of gravitational potential energy and even now you have some of the the energy because gravity is always pulling you. It is just a matter of how much gravitational potential energy you have. Go on the top Mt. Everest and you will have more gravitational potential energy than most of the people in the world.

Um... Heat?... the calorie. The metric (SI) unit for any type of energy is the Joule. Calories are convenient for small scale measurements as they are derived from specific heat and temperature, but there is a fixed relationship: 1 calorie = 4.2 Joules.

One wind turbine consumes about 20 square meters of land at its base. There are sometimes gravel roads that lead to them from the nearest road, usually 2-3 meters wide and 10-50 meters long, to allow maintenance trucks to get to them. Calling it 120 square meters per wind turbine of actual land taken out of use isn't far off.

That's about a tenth of a hectare or a quarter of an acre. The rest of the land is still useful for whatever it was being used for before, whether that was farming, hiking, growing weeds, snowmobiling, grouse hunting or just sitting there unused.

As a wind turbine will generally bring in a lease value of $5000 - $8000 per year to the owner of the land, and as that is higher than most crops will yield per acre per year, it's an excellent additional revenue stream, especially for the multi-revenue stream, small-business owners we call farmers.

As wind turbines are spaced 6-10 blade diameters apart, a gigawatt of power generation would be spread over about about 518 square kilometres, or about 200 square miles. It would take up about 0.01% of that land. If it were all compressed together, it would be about the size of a nuclear plant.

There's a US land use requirements reference at the link referenced.

Because it can be collected without running out of... sunlight.

Many resources like forests, coal, oil, etc. will (in the long run) be depleted. However, we will continue to receive light from the sun for a long time, which is why it is considered renewable.

Not sure it is renewable, its like a big fire, once its fuel is depleted it collapses into a white dwarf.

All non renewable sources can be traced back to the suns energy.

Pens are typically made from a combination of renewable and non-renewable resources. The plastic used in the pen is derived from petroleum, a non-renewable resource, while the ink and other components may come from renewable resources, such as plant-based materials.

Copper produces more electricity than aluminum due to its higher electrical conductivity. This means that copper allows for better flow of electrical current, resulting in higher electrical output compared to aluminum for the same conditions.

An alternate source of water for coastal communities can be desalination, which involves removing salt and minerals from seawater to make it suitable for drinking and irrigation. Desalination plants can provide a reliable and sustainable source of freshwater to supplement existing water supplies in coastal areas facing water scarcity.

The five types of renewable energy sources are solar energy, wind power, hydropower, geothermal energy, and biomass. These sources are continuously replenished in nature and have lower environmental impacts compared to fossil fuels.

Fossil fuels can be moved to just about anyplace to create energy on the spot. This is what allows a car to work while moving.

Tidal energy can only be created on a coast with a good tidal differential. Worthless for a landlocked country, has to be converted to something else to be transported.

Oil is considered a non-renewable resource because it takes millions of years for organic matter to decompose and be transformed into oil. Once we extract and use oil, it cannot be replenished within a human lifetime. This contrasts with renewable resources, such as solar or wind energy, which are naturally replenished on a human timescale.

Yes, nuclear energy does not produce CO2 by-products. No by-products are released into the atmosphere, all are contained within the reactor. The energy comes from a neutron colliding with a uranium atom causing it to split into two different atoms.

NO renewable energy is a good idea! Renewable means that it can be replaced so if we dont use renewable energy soon we'll be in deep trouble, and also renewable energy doesn't emit CO2, a greenhouse gas

Renewable energy is a term applied to energy resources that replenish them self.

Sustainable energy is essentially the same thing, energy resources that can be used indefinitely.

The only difference to me might be the connotations, trees can be seen as a renewable resource but might not be the best sustainable option because you have to release carbon into the atmosphere to obtain energy.

Solar energy could be called sustainable energy because your not having a negative impact by using it.

Yes, wind turbines generate electricity by converting the kinetic energy from the wind into mechanical power, which is used to drive a generator. As the wind blows, it causes the turbine blades to rotate, spinning the generator to produce electricity.

The strongest source of energy in terms of Energy density (Energy per unit volume) of all the renewable sources is Biomass.

Wind is a concentrated form of Solar Energy. Waves are concentrated forms of Wind Energy.

There is much more energy in the sunlight that strikes the Earth than in the winds that blow.

The pitch of a geothermal slinky loop refers to the spacing between each coil of the loop. This spacing is usually around 3-6 inches, depending on the specific design and size of the system. A tighter pitch can help increase the efficiency of heat transfer for geothermal systems.
