According to Reuters, «The plan gives states multiple options to achieve their emission targets, such as improving power plant heat rates; using more natural gas plants to replace coal plants; ramping up zero - carbon energy, such as solar or nuclear; and increasing energy efficiency.

The U.S. Energy Information Administration includes the following in U.S. primary energy production: coal production, waste coal supplied, and coal refuse recovery; crude oil and lease condensate production; natural gas plant liquids production; dry natural gas excluding supplemental gaseous fuels production; nuclear electricity net generation (converted to Btu using the nuclear plant heat rates); conventional hydroelectricity net generation (converted to Btu using the fossil - fuels plant heat rates); geothermal electricity net generation (converted to Btu using the fossil - fuels plant heat rates), and geothermal heat pump energy and geothermal direct use energy; solar thermal and photovoltaic electricity net generation (converted to Btu using the fossil - fuels plant heat rates), and solar thermal direct use energy; wind electricity net generation (converted to Btu using the fossil - fuels plant heat rates); wood and wood - derived fuels consumption; biomass waste consumption; and biofuels feedstock.

The comparison of costs is shown in the figure, and illustrate that carbon can be reduced much more cheaply with easy operational changes like improving power plant heat rates or increased use of natural gas combined cycle than with most renewable technologies.

Not exact matches

Example: If the product flow rate in a plant is to be increased from 10.000 to 20.000 l / h, the heat exchanger must be extended to twice the original size, provided the flow rates of the service media are also doubled, other factors being constant.

The battle is heating up over a statewide electric rate increase to subsidize upstate nuclear power plants that pits Governor Andrew Cuomo against a coalition of «good - government groups.»

Turning up the heat seems to increase the rate at which the plants produce methane, Keppler says, which could explain why atmospheric levels of methane were high hundreds of thousands of years ago when global temperatures were balmy.

«As time goes on, the rate of burning in the power plant stays the same, but the carbon accumulates, so by the end of the year, the greenhouse gases will be heating the earth much more than the direct emissions of the power plant.»

There's an under - bias in my numbers due to self consumption at power plants and especially because average emission factors understate emissions from older and smaller (higher heat rate and thus higher emissions) plants that have disproportionately been the ones shut down or not dispatched.

Today, we have limits in place for arsenic, mercury and lead, but we let power plants release as much carbon pollution as they want — pollution that is contributing to higher rates of asthma attacks and more frequent and severe floods and heat waves.

I would like to read a book about how the rate and degree of warming expected to take place over the next couple centuries compares with global warming episodes in Earth's past, and how today's plants and animals might not survive climate change and heat waves more severe than experienced during the climates in which their species evolved.

Increasing nuclear power plant efficiency from 1980 to today came from two areas: first, improvements to how operators re-fuel reactors, and keep plants and their workers safe; second, increasing the heat and electrical generation of plants through «up - rates.»

Power plants that burn natural gas are also usually more efficient at converting fuel into electricity (i.e., they have a lower heat rate) than coal - fired power plants.

The average operating heat rate for gas - fired power plants is about 21 % lower than coal - fired electric generation facilities, creating less CO2 emissions.

S. Energy Information Administration, Analysis of Heat Rate Improvement Potential at Coal - Fired Power Plants, (May 2015).

The narrower rule would focus on obtaining efficiency improvements through better heat rates at coal plants — an «inside the fenceline» regulation, rather than a sweeping change to the national power mix.

Plants can improve efficiency (heat rate) at fossil units as they have, and firms can engage in fuel switching / redispatch from coal and oil to gas and renewables, as they have.»

The official plant rating is 182.5 MW with a heat rate of 6,382 Btu / kWh (LHV) at an average annual ambient temperature of 36F.

For example, it would allow utilities to count energy intensity reductions resulting from heat rate improvements at electric generating plants, either owned by the utility or their affiliates.

Moving the current average global efficiency rate of coal - fired power plants, which supply the heat to convert water (or CO2) to steam, from today's 33 percent to 40 percent by deploying more advanced technology could cut CO2 emissions every year by 2 gigatons, which is equivalent to India's annual CO2 emissions, according to the World Coal Association.

As time goes on, the rate of burning in the power plant stays the same, but the CO2 accumulates, so by the end of the year, the greenhouse gases will be heating the Earth much more than the direct emissions from the power plant.»

The reason this rule exists is that that once - through and open - loop cooling systems withdraw high flow rates of water (up to tens of thousands of liters per kWh) into the power plant to cool the steam cycle, and then discharge that water, now heated, back to the water source.

If a regulatory program stays in place to encourage — based on reasonable technological assumptions — improved heat - rate efficiency of power plants, there is another important factor to consider.

An engineer, Kent Hawkins, evaluated several heat rate simulations to represent cycling of the plants when wind is introduced into the system.

[3] Each state has interim targets it must meet beginning in 2020, and the EPA proposed that states use a combination of four «building blocks» to achieve the emissions reductions: (1) improving the efficiency (heat rate) of existing coal - fired power plants; (2) switching from coal - fired power by increasing the use and capacity factor, or efficiency, of natural - gas combined - cycle power plants; (3) using less carbon - intensive generating power, such as renewable energy or nuclear power; and (4) increasing demand - side energy - efficiency measures.
