What are the best energy sources? "Best" depends on many factors - how the energy is being used, where it is being used, what energy sources are available, which sources are most convenient and reliable, which5 are easiest to use, what each costs, and the effects on public safety, health, and the environment. Making smart energy choices means understanding resources and their relative costs and benefits. Some energy sources have advantages for specific10 uses or locations. For example, fuels from petroleum are well suited for transportation because they pack a lot of energy in a small space and are easily transported and stored. Small hydroelectric installations are a good solution for supplying power or mechanical energy close15 to where it is used. Coal is widely used for power generation in many fast-developing countries - including China, India, and many others - because domestic supplies are readily available. Efficiency is an important factor in energy costs.20 How efficiently can the energy be produced, delivered, and used? How much energy value is lost in that process, and how much ends up being transformed into useful work? Industries that produce or use energy continually look for ways to improve efficiency, since this is a key to25 making their products morecompetitive. The ideal energy source - cheap, plentiful, and pollution-free - may prove unattainable in our lifetime, but that is the ultimate goal. The energy industry is continuing to improve its technologies and practices, to30 produce and use energy more efficiently and cleanly. Energy resources are often categorized as renewable or nonrenewable. Renewable energy resources are those that can be replenished quickly - examples are solar power,35 biomass, geothermal, hydroelectric, wind power, and fast-reaction nuclear power. They supply about seven percent of energy needs in the United States; theother 93 percent comes from nonrenewables. The two largest categories of renewable energy now in use in the U.S.40 are biomass - primarily wood wastes that are used by the forest products industry to generate electricity and heat - and hydroelectricity. Nonrenewable energy resources include coal, oil, natural gas, and uranium-235, which is used to fuel45 slow-reaction nuclear power. Projections of how long a nonrenewable energy resource will last depend on many changeable factors. These include the growth rate of consumption, and estimates of how much of the remaining resources can be economically recovered. New exploration50 and production technologies often increase theability of producers to locate and recover resources. World reserves of fossil energy are projected to last for many more decades - and, in the case of coal, for centuries.In: http://www.classroom-energy.org/teachers/energy_tour/pg5.html

In the sentence "These include the growth rate of consumption, and estimates of how much of the remaining resources can be economically recovered." (lines 47-49), "these" refers to:

One frequently overlooked area in planning is technical
reviews and inspections. A technical review requires substantial
preparation on the part of the presenters. Documents must be
published and distributed and presentation material organized and
made into slides or overheads. Practice sessions are conducted by
presenters with an audience of critics to prepare for the review.
The reviewers should read the material, attend the
presentations, and write reports. On large projects with many
reviews and walk-throughs involving many participants, a
substantial number of labor hours can be consumed analyzing
documents, attending meetings, and writing reports. For example,
a system design review for one module or unit can require 150
labor hours. When overlooked, this labor can result in a very
large error in resource and schedule estimation.
Many projects include risk assessment and risk
management as a key part of the planning process and expect the
plan toidentify specific risk areas. The plan is expected to
quantify both probability of failure and consequences of failure
and to describe what will be done to contain development risk.

It has become clear that preventive diplomacy is only one
of a class of actions that can be taken to prevent disputes from
turning into armed conflict. Others in this class are preventive
deployment of military and(or) police personnel; preventive
humanitarian action, for example, to manage and resolve a
refugee situation in a sensitive frontier area; and preventive
peace-building, which itself comprises an extensive menu of
possible actions in the political, economic and social fields,
applicable especially to possible internal conflicts.
All these preventive actions share the following
characteristics: they all depend on early warning that the risk of
conflict exists; they require information about the causes and
likely nature of the potential conflict so that the appropriate
preventive action can be identified; and they require the consent
of the party or parties within whose jurisdiction the preventive
action is to take place.

The element of timing iscrucial. The potential conflict
should be ripe for the preventive action proposed. Timing is also
an important consideration in peace-making and peace-keeping.
The prevention, control and resolution of a conflict is like the
prevention, control and cure of a disease. If treatment is
prescribed at the wrong moment in the evolution of a disease, the
patient does not improve, and the credibility of both the treatment
and the physician who prescribed it is compromised.

preventive diplomacy has just been considered the only possible action to avoid war.

Technology and legal pressure have changed
spammers’ terms of trade. They long relied on sending
more e-mails from more computers, knowing that some
will get through. But it is hard to send 100m e-mails
without someone noticing. In 2008 researchers from the
University of California at Berkeley and San Diego posed
as spammers, infiltrated a botnet and measured its
success rate. The investigation confirmed only 28 “sales”
on 350m e-mail messages sent, a conversion rate
under .00001%. Since then the numbers have got worse.
But spammers are a creative bunch.

consumers into a purchase, they are stealing their money
directly. Links used to direct the gullible to a site selling
counterfeits. Now they install “Trojan” software that
ransacks hard drives for bank details and the like.
Spammers also have become more sophisticated
about exploiting trust. In few places is it granted more
readily than on social-networking sites. Twitter, a forum for
short, telegram-like messages, estimates that only 1% of
its traffic is spam. But researchers from the University of
California at Berkeley and the University of Illinois at
Champaign-Urbana show that 8% of links published were
shady, with
Imagem 002.jpg of them leading to scams and the rest to
Trojans. Links in Twitter messages, they found, are over
20 times more likely to get clicked than those in e-mail
spam.
Nor is Facebook as safe as it seems. As an
experiment, BitDefender, an online-security firm, set up
fake profiles on the social network and asked strangers to
enter into a digital friendship. They were able to create as
many as 100 new friends a day. Offering a profile picture,
particularly of a pretty woman, increased their odds. When
the firm’s researchers expanded their requests to strangers
who shared even one mutual friend, almost half accepted.
Worse, a quarter of BitDefender’s new friends clicked on
links posted by the firm, even when the destination was
obscured.
