Machine guns, barbed wire and greatly improved artillery guns.
The heavy use of machine guns and improved artillery were the main culprits.
When coupled with the antiquated infantry tactics of mass frontal assault, etc. the effect of the machine guns and artillery was magnified exponentially.
The new technologies so far outstripped the prevailing tactical thinking it took until 1918 to see any real modification in approach and the incorporation of things such as combined arms assaults by infantry and air power and even then it was limited in scope.
The submarine also had a major impact on the war effort as Pete notes. The U-boat damned near drove Britain out of the war.
