The different sources of energy that can replace fossil fuels

Old Growth Wind power facts Wind power is now the world's fastest growing energy source and has also become one of the most rapidly expanding industries. In many ways energy is the currency of our Universe, from single celled organisms swimming in primordial pools, to colonies of Meerkats on the African savannah, to sprawling metropolises like New York, Sydney, or Beijing.

At the dawn of the first millennium AD, global population was a mere million people, reaching million by the year AD. By the dawn of the Industrial Revolution mid sfossil fuels had fueled the rapid advancement and expansion of human civilization, reaching a population of 1 billion by So where does that leave us today?

Contemporary society currently rests at 0. Enter, alternative energy - any energy source that provides an alternative to the status quo. Solar Power What better way is there to reach Type I status, than to get your energy straight from the source—solar power involves harnessing the power of our sun.

Wind Power For thousands of years, humans have harnessed the wind to push sails, mill grain, and pump water. Today, windmills use turbines to convert rotational energy into electricity that can reliably flow into to a grid. Biomass and biodiesel are among the most widely used renewable energy sources.

In stark contrast to fossil fuels which are produced by geological processes that can take millions of years, biomass typically refers to biofuels that are obtained through biological processes such as agriculture and anaerobic digestion. Fuels like bioethanol from corn or biodiesel from transesterification of plant oils burn cleaner than conventional fossil fuels and can help countries stay within their carbon budgets.

Tidal Power The rise and fall of the tides is steady and predictable, making tidal power a viable alternative source of energy for regions where high tidal ranges are available. More recently, CETO, the grid-connected wave power station off the coast of Western Australia used a series of buoys and seabed pumps to generate electricity.

Regions with high levels of geothermal activity like Iceland and Indonesia can tap into this geothermal energy available in magma conduits and hot springs to spin turbines that generate electricity or provide natural heating to homes.

We call this Alternate energy.

Global Warming

One answer to global warming is to replace and retrofit current technologies with alternatives that have comparable or better performance, but do not emit carbon dioxide. We call this Alternate energy Byone-third of the world's energy will need to come from solar, wind, and other renewable resources.

British Petroleum and Royal Dutch Shell, two of the world's largest oil companies. Climate change, population growth, and fossil fuel depletion mean that renewables will need to play a bigger role in the future than they do today.

Alternative energy refers to energy sources that have no undesired consequences such for example fossil fuels or nuclear energy. Alternative energy sources are renewable and are thought to be "free" energy sources.

They all have lower carbon emissions, compared to conventional energy sources. Combined with the use of recycling, the use of clean alternative energies such as the home use of solar power systems will help ensure man's survival into the 21st century and beyond.

Solar Power From an environmental perspective, solar power is the best thing going. The same solar system will also prevent the need to burn 60, pounds of coal.

With solar, there's no acid rain, no urban smog, no pollution of any kind. Mankind has been crazy to have not bothered to harness the sun's energy until now. Go outside on a sunny day.

"California has ambitious goals for moving from fossil fuels to renewable energy, goals that can only be met by understanding our relationship to the energy we use and the steps we must take to get to live by renewable energy.

The Energy Return on Energy Invested (ERoEI or EROI) of any energy gathering system is a measure of that system’s efficiency. The concept was originally derived in ecology and has been transferred to analyse human industrial society.

Negative environmental consequences of fossil fuels and concerns about petroleum supplies have spurred the search for renewable transportation biofuels. To be a viable alternative, a biofuel should provide a net energy gain, have environmental benefits, be economically competitive, and be producible.

While raw forms of energy are both free and practically infinite, the equipment and materials needed to collect, process, and transport the energy to the users are neither one. Currently, the RE costs are generally higher than that of fossil-based and nuclear energy. In addition to this, unlike well-established conventional designs, the advancement in different RE technologies still requires.

In contrast, most renewable energy sources produce little to no global warming emissions. Even when including “life cycle” emissions of clean energy (ie, the emissions from each stage of a technology’s life—manufacturing, installation, operation, decommissioning), the global warming emissions associated with renewable energy .
