A research on the importance of different types of renewable energy

Conventional energy technologies rely on fossil fuels which contribute significantly to many of the environmental problems we face today such as greenhouse gases, air pollution, and water and soil contamination while renewable energy sources contribute very little or not at all.

However, it is important to note that are many kinds — biomass, solar, wind, tidal, and geothermal power — and that each has its own share of advantages and drawbacks. The term covers solidliquidand gaseous fuels.

Solar energy Main article: Another common biofuel is known as biodiesel, which is produced from oils or fats using a process known as transesterification — where acid molecules are exchanged for alcohol with the help of a catalyst.

The use of fossil fuels has notably increased greenhouse gas emissions, particularly carbon dioxide, causing global warming. On the other hand, most renewable energy technologies produce little or no pollution. Agricultural waste is common in Mauritius sugar cane residue and Southeast Asia rice husks.

Feed-in tariffs FITs Several states and individual electric utilities in the United States have established special rates for purchasing electricity from certain types of renewable energy systems.

Costs of lithium ion batteries are dropping rapidly, and are increasingly being deployed as fast acting sources of grid power i. A diversified portfolio of energy assets contributes to a long-term, sustainable energy strategy that protects the power supply from market fluctuations and volatility.

In some states, customers can sell the excess electricity that they generate with their systems to the utility. Long-term certainty Renewables have been heavily encouraged by policy measures and financial support, with the explicit aim of driving costs down through early deployment.

Most of the research and development is carried out at the National Labs and in cooperation with academic institutions and private companies. Biodiesel is produced from oils or fats using transesterification and is the most common biofuel in Europe.

China is the largest producer of hydroelectricity in the world and has more than 45, small hydro installations. This style of generation may still produce a large amount of electricity, such as the Chief Joseph Dam on the Columbia river in the United States.

Several states have their own renewable fuel standards or requirements. The biomass used for electricity generation varies by region. Biomass simply refers to the use of organic materials and converting them into other forms of energy that can be used.

Gaseous biofuels include biogaslandfill gas and synthetic gas. Historically hydroelectric power came from constructing large hydroelectric dams and reservoirs, which are still popular in third world countries.

What are the Different Types of Renewable Energy?

Every state has some financial incentives available to support or subsidize the installation of renewable energy equipment. Renewable portfolio standards RPS and state mandates or goals A renewable portfolio standard RPS typically requires that a percentage of electric power sales in a state comes from renewable energy sources.

Initially, photovoltaic power was only used for small to medium-sized operations, ranging from solar powered devices like calculators to household arrays. Biodiesel, another transportation fuel, can be produced from left-over food products such as vegetable oils and animal fats.

What are the different types of renewable energy?

Hydropower is produced in countries, with the Asia-Pacific region generating 32 percent of global hydropower in The energy costs for producing bio-ethanol are almost equal to, the energy yields from bio-ethanol. Traditionally, tidal power has suffered from relatively high cost and limited availability of sites with sufficiently high tidal ranges or flow velocities.

The choice is up to us, whether we should adopt the usage of renewable resources now or wait till when earth is left with nothing but a polluted environment and an ailing population.Energy Storage Technologies & Their Role in Renewable Integration.

I With the growing importance of renewable energy sources, scientist and engineers are anxious to enhance efficiencies and to lower the costs of these technologies. Yet, there different types.

Renewable Energy is an international, multi-disciplinary journal in renewable energy engineering and research. The journal aims to be a leading peer-reviewed platform and an authoritative source of original research and reviews related to renewable energy. Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.

The importance of Renewable energy Essay Sample

Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services. According to the International Renewable Energy Agency (IRENA), doubling the renewable energy share in the world energy mix, to 36% bywill result in additional global growth of % by that year (equivalent to trillion dollars), a increase in wellbeing of % and in employment in the sector of up to more than 24 million people.

The Database of State Incentives for Renewable Energy and Efficiency (DSIRE) is a comprehensive source of information on the types and the status of government and utility requirements and incentives for renewable energy.

Renewable energy is a critical part of reducing global carbon emissions and the pace of investment has greatly increased as the cost of technologies fall and efficiency continues to rise.
