| The construction of hydropower plants can alter sizable portions of land when dams are constructed and lakes are created, flooding land that may have once served as wildlife habitat, farmland, and scenic retreats. Hydroelectric dams can cause erosion along the riverbed upstream and downstream, which can further disturb wildlife ecosystems and fish populations. There are three types of hydropower facilities: impoundment, diversion, and pumped storage. Some hydropower plants use dams and some do not. |

| Hydroelectric power plants affect various fish populations in different ways. Most notably, certain salmon populations in the Northwest depend on rivers for their life cycles. These populations have been dramatically reduced by the network of large dams in the Columbia River Basin.1 When young salmon travel downstream toward the ocean, they may be killed by turbine blades at hydropower plants. When adult salmon attempt to swim upstream to reproduce, they may not be able to get past the dams. For this reason, some hydroelectric dams now have special side channels or structures to help the fish continue upstream. |

Hydropower
With 80,000 megawatts of generating capacity, hydropower is the nation's largest renewable electricity source. Working with industry, the Wind and Hydropower Technologies Program pursues R&D to develop more environmentally friendly technologies to maintain the nation's existing hydropower capacity.
How Hydropower Works.
Hydropower is using water to power machinery or make electricity. Water constantly moves through a vast global cycle, evaporating from lakes and oceans, forming clouds, precipitating as rain or snow, then flowing back down to the ocean. The energy of this water cycle, which is driven by the sun, can be tapped to produce electricity or for mechanical tasks like grinding grain. Hydropower uses a fuel—water—that is not reduced or used up in the process. Because the water cycle is an endless, constantly recharging system, hydropower is considered a renewable energy.
When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. There are several types of hydroelectric facilities; they are all powered by the kinetic energy of flowing water as it moves downstream. Turbines and generators convert the energy into electricity, which is then fed into the electrical grid to be used in homes, businesses, and by industry.
What is Hydropower?
Hydroelectricity is electricity obtained from hydropower. Most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator. Less common variations make use of water's kinetic energy or undammed sources such as tidal power. Hydroelectricity is a renewable energy source. Hydroelectric energy is a renewable energy source dependent upon the hydrologic cycle of water, which involves evaporation1, precipitation2 and the flow of water due to gravity.
The energy extracted from water depends not only on the volume but on the difference in height between the source and the water's outflow. This height difference is called the head. The amount of potential energy in water is directly proportional to the head. To obtain very high head, water for a hydraulic turbine may be run through a large pipe called a penstock.
1 Evaporation is the process whereby atoms or molecules in a liquid state gain sufficient energy to enter the gaseous state.
2 In meteorology, precipitation is any kind of water that falls from the sky as part of the weather.

Tobacco History:
The Social History of Smoking
by George Latimer Apperson
First published in 1914
"The Social History of Smoking" by George Latimer Apperson, can be purchased at Amazon.com in two different versions. Depending on the quality of the edition, prices range between $35 and $104.
From Chapter 1: It may further be added that though the use of tobacco was known and practised on the continent of Europe for some time before smoking became common in England—it was taken to Spain from Mexico by a physician about 1560, and Jean Nicot about the same time sent tobacco seeds to France—yet such use was exclusively for medicinal purposes. The smoking of tobacco in England seems from the first to have been much more a matter of pleasure than of hygiene.
From Chapter 7: The most famous of country clergymen of the early Georgian period is, of course, Fielding's lovable and immortal Parson Adams. Throughout "Joseph Andrews" the parson smokes at every opportunity. At his first appearance on the scene, in the inn kitchen, he calls for a pipe of tobacco before taking his place at the fireside. The next morning, when he fails to obtain a desired loan from the landlord, Adams, extremely dejected at his disappointment, immediately applies to his pipe, "his constant friend and comfort in his affliction," and leans over the rails of the gallery overlooking the inn-yard, devoting himself to meditation, "assisted by the inspiring fumes of tobacco." Later on, in the parlour of the country Justice of the Peace, who condemned his prisoners before he had taken the depositions of the witnesses against them, and who, by the way, also lit his pipe while his clerk performed this necessary duty, Adams, when his character has been cleared, sits down with the company and takes a cheerful glass and applies himself vigorously to smoking. A few hours later, when the parson, Fanny, and their guide are driven by a storm of rain to take shelter in a wayside ale-house, Adams "immediately procured himself a good fire, a toast and ale, and a pipe, and began to smoke with great content, utterly forgetting everything that had happened." In the same inn, after Mrs. Slipslop has appeared and disappeared, Adams smokes three pipes and takes "a comfortable nap in a great chair," so leaving the lovers, Joseph and Fanny, to enjoy a delightful time together.
