The prospects for renewable energy are
enhanced through the use of hydrogen energy systems in which hydrogen is an
energy carrier. As easily accessible fossil fuel supplies become scarcer and
environmental concerns increase, hydrogen is likely to become an increasingly
important chemical energy carrier. As the world’s energy sources become less
fossil fuel-based, hydrogen and electricity are expected to be the two dominant
energy carriers for the provision of end-use services, in a hydrogen economy.
Thus, hydrogen energy systems allow greater use of renewable energy resources.
In this paper, the role of hydrogen as an energy carrier and hydrogen energy
systems, and their economics, are described and reviewed.
Net-zero energy buildings and communities,
which are receiving increasing interest, and the role of energy storage in them,
are described. A net-zero energy building or community is defined as one that,
in an average year, produces as much energy from renewable energy as it
consumes. Net-zero energy buildings and communities and the manner in which
energy sustainability is facilitated by them are described and examples are
given. Also, energy storage is discussed and the role and importance of energy
storage as part of net-zero buildings and communities are explained. The NSERC
Smart Net-zero Energy Buildings Research Network, a major Canadian research
effort in smart net-zero energy buildings and communities, is described.
Over 300 British adults completed the Hogan
Development Survey (HDS) (Hogan & Hogan, 2001), a measure of the
personality disorders and the Bar-On Emotional Quotient Inventory (EQi) (Bar-
On, 2004). Work associates known to the participants also completed an
observers’ version of the EQi. The structures of both inventories were
examined. The HDS factored into three clear factors (clusters A, B, C)
confirming previous analyses while the EQi had a single factor structure.
Cluster B disorders (labelled Moving Against People) were
correlated negatively with the Stress scale on the EQi while Cluster A
disorders (labelled Moving Away from People) were negatively
correlated with Intrapersonal, Interpersonal and Mood subscale scores on the
EQi. Regressions showed that Avoidant, Schizoid and Narcissistic disorders most
consistently related to the self-reported EQi subscale scores. Interestingly
Paranoia was positively correlated with the total and the Intrapersonal EQi
scores. Participants tended to have higher self, compared to observer scores on
the EQi. Only one regression was significant: participants with lower
Borderline and Schizotypal scores were seen to be better at Stress management.
